4 Introduction General Dear User Thank you for using the CAPS program from Grundfos. The purpose of this program is to offer a complete tool that contains an extensive catalogue of Grundfos products and a sizing program to select the most suitable pump for your application. On top of that there is a comprehensive pump replacement function for heating circulators and the possibility to produce professional quotations including curves, drawings, quotation texts, wiring diagrams etc. You can also export all this in the most popular file formats including gif, bmp, txt, dxf, etc. Last but not least the program contains the instruction and operating manuals for nearly all pumps of Grundfos in multiple languages. Service drawings, exploded views and parts lists are available for all sewage products as well as several other pump types. The program is designed, developed and maintained especially by Grundfos in order to make use of the wide experience of more than half a century designing pumps and knowledge of applications. For the last 20 years Grundfos has developed the CAPS software, so customers and professionals all over the world can share and benefit from this experience. CAPS is available in two version; WinCAPS is available on a CD-ROM and the online version called WebCAPS is available at the Grundfos website - Additional features in WebCAPS include CAD Drawings and Literature. Who should use this program? WinCAPS has specific advantages for all professional users Generally, everybody who is involved with pumps in a professional manner will find this program useful, however there are certain specific groups of users that will benefit especially from this program as mentioned below. Installers, Well drillers, Industrial end users or Owners of a Grundfos product If you belong to one of these groups then you can use CAPS typically to make selections from the catalogue, by product number or by using the books on the screen. If you do occasionally need to calculate a pump (in sizing), you will probably only use the short standard question catalogue. Also the replacement catalogue can be helpful when you need to replace an existing pump with a Grundfos pump. We advise you to run the program straight from the CD in order to save the space on the hard disk. Planners, Consultants, Engineers, Large installation companies, Pump dealers and Students If you are in one of the above groups you will probably appreciate, apart from the catalogue function, the advanced question catalogues in the sizing program and the ability to make accurate energy consumption calculations based on your own load profile (consumption pattern) You can also make comparisons against existing systems and calculate savings and payback periods. Dimensional drawings can be used as reference in new or replacement projects. Grundfos Staff and Service partners This group uses CAPS as reference for all Grundfos products. Many pumps have exploded views and parts lists connected to them, which are useful when ordering spare parts. Via or fax, a salesman, service engineer or wholesaler can send drawings, technical information, manuals and pumping solutions to their customers. Regular updates of the database and the program will always supply the latest information. For news and updates please check. or

For details on which products are added and removed from which versions please go to the CAPS support pages at: What s new in WebCAPS ? WebCAPS contains further optimization of WebCAPS as well as bug-fixing. Japanese language is now available in WebCAPS. It is also possible to find the product number for a configured product, if it already exists in the product database. A crash in some of the calculators in Heating sizing has also been fixed. Duty point specific is now possible for Hilge products. What s new in WebCAPS ? WebCAPS also contains further optimization of WebCAPS as well as bug-fixing. A number of bug fixes to Pressure boosting sizing have been implemented insuring that the correct pump is selected. An error concerning printouts of motor sheets has also been fixed. What s new in WebCAPS ? The main new feature in WebCAPS is the introduction of a new configuration tool in Catalogue for the CM product family. The technique is based on Configit standard configuration software, which offers a faster and more precise outcome of the user s configuration input. It is a requirement that the search criteria limit the search below 100 hits, which is done by selecting relevant configuration parameters accordingly. Until then the submit button will not be active. WebCAPS also contains further optimization of WebCAPS as well as bug-fixing. In Catalogue, an LCC tab is added in the ProductDetail window if LifeCycle Cost Calculations have been done. Optional print of zeta values in Wastewater sizing has been added. Better integration between Guided Search and Literature Search. What s new in WebCAPS ? Once again the focus has been on improving the existing features in WebCAPS as well as bug-fixing. Among the new features in WebCAPS is replacement from CH to CM pumps. Errors related to the pipe friction losses calculators in Wastewater Sizing have been fixed. An error related to the display of service videos in Internet Explorer has been fixed.

7 What s new in WebCAPS ? Sizing A new sizing wizard is introduced for Renewable Energy. The wizard guides the user through the process of sizing a pump for solar or wind systems in a limited number of steps. Overview mode is now available for all sizing applications. Replacement Replacement for S pumps is now available for S pumps

8 Product Detail For motors new features in form of Sound and Vibration measurement reports have been introduced. Those two reports on all MG Eff1 motors can be downloaded or printed directly from CAPS as PDF files. Both the Sound and Vibration reports are available in 50 & 60 Hz depending on the settings chosen in CAPS.

9 Duty point specific settings for HS pumps is now possible:

10 Getting started with CAPS CAPS consists of 6 main program areas: * Catalogue * Sizing * Service * Replacement * Literature * CAD Drawings The Catalogue contains pump curves, product pictures, dimensional drawings, wiring diagrams, technical data and quotation texts as well as information on service and part lists for Grundfos products. When clicking on the preferred duty point in the curve viewer, the pump best suited to your hydraulic needs is selected. It is also possible to select a pump from a list of search criteria. The Sizing tools are where Grundfos utilizes its long experience in pump design and application knowledge. This results in a very comprehensive, yet easy to use program that is almost always able to produce a suitable pump for your application. The sizing tools are wizard-based; The wizard contains a number of steps with each step consisting of questions relating to the application you wish to size a pump for. Adjust the values and settings to suit your preferences or simply enter your required Flow and Head values and start the sizing. In Service you can view interactive exploded views and sectional drawings of Grundfos products. In Replacement you can easily find a Grundfos pump to replace your existing pump. Simply select the characteristics of your existing pump from a list of search criteria to see which Grundfos pump to replace it with. Literature contains technical documentation for Grundfos products. You can find a product by either application area or by searching for a specific product number. The technical documentation is available for viewing and download in pdf format. In CAD Drawings you can download technical drawings of Grundfos products in dxf- and dwg formats. You can save your selections and quotations in the Projects part of CAPS and make professional printouts including quotation texts, curves, dimensional drawings etc. It is also possible to add local accessories.

11 CAPS, a quick tour How CAPS is built up The catalogue and sizing part of the program are divided in application areas. Allocated to these areas are the Grundfos pump series. If you want to know which series are allocated to which application, go to catalogue and click on an application book. Layout of the screen CAPS screen areas After starting up CAPS you can see that the program interface is divided up in several areas (see illustration) The menu bar. The five buttons that control the five different program areas The curve viewer. This part of the screen displays curves, drawings, photo's etc The text viewer. This is where texts are displayed that is connected to the selected article. When selecting an accessory this will display the accessory information. The middle button bar, used to close screens, start the sizing process or selection fields in the catalogue. The result grid/hit list. Here is where the products are shown that are the result of the sizing process or a catalogue selection

12 The lower button bar. The left side contains the buttons Information and Accessory. When a product is selected either in the catalogue or in sizing, clicking on the Information button will give access to the Operating and Installation instructions of that product, and if available, service drawings, exploded views and parts lists. The right side contains three buttons and a short cut to the print menu. With the button "Start Page" you can go back to the opening screen of the program. The "Add to project button" will add your current selection to a project (see chapter on Projects) and the "View Project" button will take you straight to the project screen.

13 Catalogue General A very powerful feature of CAPS is the catalogue function. Choosing catalogue with the button, a bookcase or tree structure will open that contains books with the names of applications in which you will find your pump. If you are not certain which application holds the pump series you are looking for, you can also choose the book that contains all products. Selecting a product in the catalogue Selection by product number If you already know a specific product number and want to obtain data, just type the number in the field "Product Nr", located on the left side of the middle button bar (see Layout of the screen), and press the button with the binoculars. Browsing through the catalogue Select the correct frequency in the middle button bar (default = 50 Hz). Clicking once on a book will make the book drop from the case and show an application picture. Clicking twice (double click) on a book will take you one level deeper and show you the product lines that are allocated to the application. If you click once on a book of a product line, a photo of that particular product range will pop up. If you click twice on the book you will go one level deeper into that product range. Again, clicking once on the book will show you a picture of the chosen pump type in the product range; double clicking will bring up a search panel. This search panel is different for every product line and you can choose in the Options menu whether you want the simple or extended search panel. You can see more data in the catalogue by pressing these buttons Sort your product by clicking on the headings If nothing is selected in the search panel, all products in the selected product line will show up in the result grid. On the right hand of the middle button bar three buttons appear. Clicking these buttons will display different data of the pumps in the result grid (General Data, Mechanical Data and Electrical Data). The products in the result grid can be sorted by clicking on the headings of the columns. Access Instruction Manuals, Service Drawings and Service Kits You can highlight a specific product in the result grid with your mouse and you will see the buttons "Information" and "Accessory" lighten up. Clicking on "Information" will give you access to the Installing and Operating instructions

14 Double clicking on a specific product in the result grid will give you access to the Pump Curve, Dimensional Drawing, Product Picture and Wiring Diagram on the left side of the screen and All Data, Quotation Texts and a System summary on the right side. All this data can be exported, printed or saved in a project. Important: The accessories are applicable for the whole product line that you selected and not only the pump that is in the result grid. You have to choose the correct accessory yourself from the accessory menu; e.g. if your pump has DN 40 connections, you need to select DN 40 flanges from the flanges database. If Service information is available for this product number, a button appears under the pump curve. Double-clicking on a "+" sign in the parts list viewer will reveal a lower level for the kit. Search for EAN Numbers Apart from a product number search, it now also possible to search for a particular EAN number in the catalog. Click and choose from capacity range A great new feature is the "click and choose" functionality using the graph of the complete range of a certain pump range. You have to activate the "Use the extended search panel in the catalog" function in the "Options" menu.

15 Capacity range screen If you select a certain pump series in the catalog, a new window will open, showing the complete capacity range for these models. Clicking anywhere in the graph will result in a pre-selection of certain models of this range, depending on the Q and H. Copy from the Selection Table (Hit list) If you right-mouse click on a cell in the selection table, the data in this particular cell can be copied to a word processor or a spreadsheet program. For a mass export of the data in the selection table you can still use File/Export/Hit list Viewing the pump curve in the catalogue area, extensive possibilities Once you selected a pump in the catalogue, the pump curve will appear on the left side of the screen. In this curve screen, very sophisticated features are at your disposal. To begin with, you can click anywhere in the curve area and the duty point and the efficiency of the pump will be calculated immediately, and displayed in right side of the curve screen. If you are looking at the curve of a nonspeed controlled pump, the calculated duty point is where the pipe resistance curve crosses the pump curve. If you are looking at the curve of a speed controlled pump (which can be identified by a large blue area), clicking anywhere in this area will give you the requested duty point and the of the pump in this duty point - as percentage of nominal speed

16 The button "Curve Settings" activates the next important feature. Clicking this button will show you the Curve Settings Menu with the following possibilities. All curve settings are automatically saved until pressing the "Default Settings" button restores the default values The Curve Setting dialogue is divided into to 5 main areas, which can be accessed by clicking the different tab in the dialogue. Operating point tab You can choose to have no duty point displayed, the nominal (optimal) duty point or a duty point that you can define yourself. To define a duty point yourself, select Input. If there is already a static pressure in the system, you can input that here as well. The pipe resistance curve will then start from that point on the Y-axis. CAPS will allow you to fill in here a different motor speed in the Nominal Motor Speed field to emulate the effect on the pump curve of an electrical motor that has a different speed than the fitted standard motor. CAPS allows an input of 5% under the original nominal motor speed or up to the synchronous speed (2999 RPM for 2 pole motors, 1499 RPM for 4 pole motors, 999 RPM for 6 pole motors). Impeller For some pumps series (e.g. the NK series long coupled end suction pumps) there is a possibility to show a curve based on an impeller diameter of your choice. (The desired diameter has to be within the limitation for the particular pump, otherwise there will be no curve shown; clearing this field will restore the default values). This is due to the fact that Grundfos can supply these pumps with an impeller machined down to match the exact desired duty point if this is requested Hydraulic layout tab In this part of the menu you can choose to emulate the curves of maximal six pump working parallel or two pumps working in series.

17 Variable speed This powerful feature allows you to turn the curve of a non-speed controlled pump into a speed-controlled pump, thereby emulating the effect of an external frequency converter. If this feature is activated, the curve area will turn blue. Clicking in this blue area will show you the duty point together with the corresponding RPM in % of nominal speed in the top right hand corner of the curve. This can serve as a reference point for the frequency setting (Hz) of the external frequency converter. (The slip of the motor has to be taken into account so in reality this setting might vary slightly). If you have selected pumps in parallel, you can select if you want to enable variable speed for one pump only or for all of the pumps in parallel. The Variable speed feature is not available for wet runners or pumps with multiple curves Fluid tab In the Pumped liquid field, you can choose from a list predefined medias primary used as Antifreeze/Secondary fluids in heat transfer. If you want to input viscosity and density for the media yourself, select "Any viscous fluid" in the list.

18 IMPORTANT: These calculations are only applicable for "Newtonian Liquids", check chapter Working with Glycol Solutions Basically changing the viscosity will influence the steepness of the curve and adjusting the density will influence the power consumption. However also factors like the design of the pump, duty point, RPM and impeller size play a role in the calculation. When the required power (P2) exceeds the fitted standard motor, the pump curve becomes a dotted line. Curve types tab Curve types Depending on the product range and position in the program, some curves may or may not be available. Tolerances The calculation and display of the duty point tolerances has changed. For some pump types no tolerances are displayed and the checkbox in the curve viewer is grayed out. The tolerances that are being displayed are according to ISO 9906 Annex A Important. Not all curves are available for all pump types and not all Grundfos curves are according ISO 9906 Annex A, for details check your Grundfos dealer or the Grundfos.com website. Depending on the version of CAPS the possibility to display the tolerances may or may not be available Show control curves Whenever you have a speed controlled pump, this option is available. If it is clicked, further options appear. You can choose between two different control curves - a rectilinear or a square curve form. As default, the control curve is rectilinear. Mark the "Square curve form" to enable this option. The "Decrease at low flow" input tell CAPS how steep the control curve should be. The value decreases the head value for the control curve at zero flow according the actual head. The "Minimum flow" input tells where to stop the control curve.

19 Other Curves tab Show curves for pumps with nearby stages If this box is ticked, also pump curves will be displayed of the same product line with more- or less stages. This functionality is available depending on the product line. Show curves for (other) pumps in the hit list This box is available in Sizing only. If this box is ticked, curves from other pumps in the hit list can be shown in the curve screen. Insert your own QH point Here you can insert manually a QH point and a P1 at this particular point. CAPS will then automatically calculate the efficiency of that pump in this point. This functionality comes in handy when you have to compare an existing pump, of which you know the power consumption at a given QH, with a selection made by CAPS. Default Settings Button This button will restore the default curve settings. Important: The above features in the curve viewer are only available when you select a pump in the catalogue mode. When you select a pump using the sizing process, some features are not available. Multiple Curves In case you want to modify your pump performance curve sheet to include more information you should enter the Curve settings. The options you select here will be shown in the curve viewer and in your print-outs as well. By activating the function "show curves for (other) pumps in the hit list" in the Curve settings window, you can compare different pumps from the hit list. By selecting the "show curves for nearby stages" in the Curve settings you will get the option to see more curves for pumps with more or less stages in comparison with the sized pump curve. By clicking any place in the curve viewer, the nearest pump curve will show up when this function is activated.

20 Sizing - Heating Getting started with Sizing The sizing tool is where Grundfos utilizes its long experience in pump design and application knowledge. This results in a very comprehensive, yet easy to use program that is almost always able to produce a suitable pump for your application. The sizing tool is divided in 8 main application area's that are again subdivided in sub application areas. Depending on which market or country CAPS is used, applications and sub applications can vary. Each application comes with its own specific question catalogue. An important feature of these question catalogues is the possibility to quickly select a pump using only basic input concerning Head and Flow, make advanced calculations with regard to energy consumption, payback periods, load profiles, cost of ownership etc. The Sizing Wizard, a quick tour The Sizing Wizard basics A sizing wizard is a guide intended to help the user narrow down and find the right product for his needs. The wizard contains a number of steps with each step consisting of questions relating to the application you wish to size a pump for. Adjust the values and settings to suit your preferences or simply enter your required Flow and Head values and start the sizing. However, some input fields are interdependent, so we recommend you to follow the order suggested in the program. Use the `Next' and `Back' buttons to navigate between the steps in the wizard. Click the `Start sizing' button. Calculations will be carried out on the basis of your input. After a few seconds, a list of relevant pump solutions is displayed at the bottom of the screen, ranked in order of relevance. You can then access further details by double clicking your preferred pump solution.

21 Click the button Some of the input fields have a button next to them. When you click the button, a sub-window will appear, allowing you to enter additional input or perform a calculation. Entering extra input here will ensure even more accurate and detailed sizing calculations and printout data. Saving and loading Settings in Sizing All the input that you make in a wizard, such as head, flow, a load profile, etc. can be saved using the "Save as" button. These settings can be reloaded again using the "Open" button. Default settings CAPS allows you to set and save your own default settings within each sizing wizard. When you mark the `Use as default sizing input' in the `Save sizing input' dialogue, all your input in the sizing wizard, except for Flow and Head, will be reloaded the next time, you enter the sizing wizard. Heating The heating sizing area is mainly used to select pumps for domestic, commercial or district heating as well as industrial plant service systems. Selecting the application area is the first step of the wizard

22 Select type of Installation Within each application area the user can select the type of installation he wants to size a pump for. The types of installations are divided into groups to make it easier for the user to find the correct installation type. Your Requirements At this step, the user can enter the Flow and Head values, which are essential in the sizing process.

23 If the user does not know the exact Flow and Head values, two calculators are available to help define the values (available in Commercial Buildings, but not District Heating). The Flow calculator Enter the values that apply to your system and click OK to get a calculated flow value. The Head calculator

24 Enter the values that apply to your system and click OK to get a calculated head value. Besides Head and Flow, there are other settings in Your Requirements: Max. liquid temperature: This input not only includes or excludes certain pump ranges; it also determines the choice of seal. Max. operation pressure: This input sets the maximum operation pressure for the system. Min. and max. inlet pressure: Here CAPS checks if the minimum inlet pressure, combined with the vapor pressure of the liquid at the maximum liquid temperature and the flow that was specified, is still within the NPSH limits. In other words, depending on the pump type, if the inlet pressure is too low, combined with a certain liquid temperature and flow, there is danger of cavitation. Therefore CAPS will exclude pump types with NPSH values that are not within this range anymore. This can cause wet runners to be excluded from certain selections. Note! Once the Flow and Head values have been entered, the `Start sizing' button is activated and it is possible to get a recommendation. Control mode Select the control mode, which is most suitable for your selected type of installation. By default, WinCAPS has selected the control mode most often used for the selected type of installation, but the user can always select another control mode. The available control modes are defined by the input, the user has made earlier in the wizard, so it is not possible to select a control mode that cannot be used for the selected type of installation. The user can also decide if a frequency converter should be included and if it should be integrated or external. Load Profile An important feature in CAPS Sizing is the ability to provide an accurate calculation of energy consumption based on a given load profile.

25 CAPS lets you select between different load profiles; the `Standard profile' is a heating pump profile, while the `Full load' profile sees the pump always operating at a fixed duty point. You can also define your own load profile by selecting `User profile' and edit the values in the input fields. You can also alter the length of the Heating season, which is used in the calculation of the energy consumption. Configuration At this step you define you define the configuration of your system. Select `Single' if you prefer one pump. Select `Twin pump' if you prefer two pumps in alternating operation or with a second pump in standby.

26 Select `2 pumps' if you prefer two pumps in parallel operation, which means that the total requested capacity is divided over the two pump heads. If the user selects `Parallel', a set of additional questions appears allowing the user to set the total number of pumps and number of pumps in standby. Pump design If the user has a preference concerning pump material, this can be set in the drop down menu. Choose between Inline Canned Rotor type (wet runners), Inline and End Suction, close coupled (dry runners) and End Suction, long coupled (base plate pumps). If you select the long coupled pumps and additional questions will appear concerning the desired coupling type. Operational conditions At this step, the user can set the operational conditions for the pump including frequency, phase, power supply and voltage. CAPS will take these conditions into account when a reaching a sizing result.

27 Hit list settings At this step, the user can set hit list settings for the outcome of the sizing process. This is also the last step before the sizing result reached. Limit search to..: This gives the user the option of pre-setting the outcome of the sizing process based on the inputs made previously in the sizing process. Include particular pump in hitlist: This gives the user the option of pre-selecting a specific pump to be included in the hitlist. This can be useful for comparing a known pump with the sizing result. Allow uncontrolled: If this option is marked, then an uncontrolled pump can also be included in the hitlist provided it meets the requirements set by the user during the sizing process. Max. hits per product group: Set the number of hits allowed per product group Max. hits total: Set the total number of hits wanted in the hit list. Evaluation criterion: The order of the results after pressing the `Start sizing' button depends on the "Evaluation Criterion" settings. By default this setting will be set to `Price + energy costs', but it is also possible to order the results in the hit list by `energy consumption' alone. Energy price: Set the energy price used to order the sizing results in the hit list Calculation period: Set the number of years used in the Life Cycle Cost calculation Grundfos recommends This is the result of the sizing wizard's calculations. The left column in the window shows an input overview detailing the inputs entered at the different steps in the wizard. The right column of the window (below Grundfos recommends) shows the recommended pump followed by the quotation text describing the pump

37 Sizing - Groundwater Supply Getting started with Sizing The sizing tool is where Grundfos utilizes its long experience in pump design and application knowledge. This results in a very comprehensive, yet easy to use program that is almost always able to produce a suitable pump for your application. The sizing tool is divided in 8 main application area's that are again subdivided in sub application areas. Depending on which market or country CAPS is used, applications and sub applications can vary. Each application comes with its own specific question catalogue. An important feature of these question catalogues is the possibility to quickly select a pump using only basic input concerning Head and Flow, make advanced calculations with regard to energy consumption, payback periods, load profiles, cost of ownership etc. The Sizing Wizard, a quick tour The Sizing Wizard basics A sizing wizard is a guide intended to help the user narrow down and find the right product for his needs. The wizard contains a number of steps with each step consisting of questions relating to the application you wish to size a pump for. Adjust the values and settings to suit your preferences or simply enter your required Flow and Head values and start the sizing. However, some input fields are interdependent, so we recommend you to follow the order suggested in the program. Use the `Next' and `Back' buttons to navigate between the steps in the wizard. Click the `Start sizing' button. Calculations will be carried out on the basis of your input. After a few seconds, a list of relevant pump solutions is displayed at the bottom of the screen, ranked in order of relevance. You can then access further details by double clicking your preferred pump solution.

38 Click the button Some of the input fields have a button next to them. When you click the button, a sub-window will appear, allowing you to enter additional input or perform a calculation. Entering extra input here will ensure even more accurate and detailed sizing calculations and printout data. Saving and loading Settings in Sizing All the input that you make in a wizard, such as head, flow, a load profile, etc. can be saved using the "Save as" button. These settings can be reloaded again using the "Open" button. Default settings CAPS allows you to set and save your own default settings within each sizing wizard. When you mark the `Use as default sizing input' in the `Save sizing input' dialogue, all your input in the sizing wizard, except for Flow and Head, will be reloaded the next time, you enter the sizing wizard. Groundwater Select type of Installation At this step the user selects the type of installation he wants to size a pump for. The types of installations are divided into three groups to make it easier for the user to find the correct installation type. The three groups are Borehole, Reservoir and Submersible in Sleeve.

39 Your Requirements At this step, the user can enter the Flow and Head values, which are essential in the sizing process. If the user does not know the exact values beforehand, two calculators are available to help set the values. The Flow calculator

40 The Flow calculator allows you to adjust the unit used to describe the capacity requirement (days or years). You can also enter data on operating hours and days. Input for flow oversize and flow undersize makes it possible for you to define how close you want the pump solution should be to the required duty point. But note that a too narrow band could limit the output and thus exclude the most energy optimal solution. The Head calculator The required pumping Head calculator lets you enter more detailed information about head. It will also support calculations of total head. Entering data for Test flow enables the programme to take into account that the dynamic water level varies depending on the actual flow. Note that calculations concerning the electrical cable diameter are also carried out here. Besides Flow and Head other settings are also included at this step: Variable speed: By entering "yes" in the Variable speed input field; you can include the efficiency of a frequency converter in your calculations. The required speed (Hz) of the pump will then be calculated and the performance curve at this speed will be shown. Allowed flow over- and undersize: Here you can define in percentage, how much you allow for under or over dimensioning.

41 Configuration The Configuration step enables you to configure your pump in regard to connection type, pump material and motor type. Operational conditions At this step of the wizard, the user can set operational conditions for the pump including frequency, phase and voltage. CAPS will take these conditions into account when a reaching a sizing result. Besides the electrical data, the user can also set the preferred Life Cycle Cost settings: Evaluation criterion: The order of the results after pressing the `Start sizing' button depends on the "Evaluation Criterion" settings. By default this setting will be set to `Price + energy costs', but it is also possible to order the results in the hit list by `energy consumption' alone. Energy price: Set the energy price used to order the sizing results in the hit list Calculation period: Set the number of years used in the Life Cycle Cost calculation

42 Hit list settings At this step, the user can set hit list settings for the outcome of the sizing process. This is also the last step before the sizing result reached. Limit search to..: This gives the user the option of pre-setting the outcome of the sizing process based on the inputs made previously in the sizing process. Include particular pump in hitlist: This gives the user the option of pre-selecting a specific pump to be included in the hitlist. This can be useful for comparing a known pump with the sizing result. Max. hits per product group: Set the number of hits allowed per product group Max. hits total: Set the total number of hits wanted in the hit list. Grundfos recommends This is the result of the sizing wizard's calculations.

43 The left column in the window shows an input overview detailing the inputs entered at the different steps in the wizard. The right column of the window (below Grundfos recommends) shows the recommended pump followed by the quotation text describing the pump Tip By clicking with your right mouse button, you can save results from the hit list in your clipboard and from there, paste it into for instance a spreadsheet. How to calculate the drawdown of a well in Groundwater section If the Static water level (at test flow) is 80m and the Dynamic water level (at test flow) is 100m, drawdown is 20m (80 to 100M) and when the test is done at 120 m3/h Test flow (from drilling report) the specific capacity is 6m3/h/m. If dimensioning flow Q=60m3/h is chosen this means that the drawdown is 60/6 = 10m and the dynamic level is 90m. This head will be used by CAPS to calculate the correct pump. CAPS will display the calculated drawdown of the well at the dimensioning flow in the Sizing Result screen, as well as the specific capacity of the well. The rules are as follows: If the "Test Flow from drilling report" field is empty, it is assumed that the dimensioning flow is also the test flow. The drawdown and specific capacity are calculated from the dimensioning flow. If the "Dynamic Water Level at test Flow" field is empty, it is assumed that the static water level is also the dynamic water level and there is no drawdown and no specific capacity

Sewage and Wastewater Grundfos offers a complete range of sewage and wastewater pumps, from cellar draining pumps up to wastewater pumps from 600 kw and m3 per hour (The presence of these bigger pumps in CAPS depends on local circumstances), complete with accessories. Select application area This is the first step of the Wastewater sizing wizard and at this step, the user selects the application area: Commercial buildings, Domestic buildings or Municipal wastewater. The further questions in the sizing wizard

52 will be based on this selection and adapted to the selected application area and also narrowed down to the suitable pump ranges and pump types. Select subapplication Each application area includes a number of sub-applications indicated by the dotted boxes on the screen. Point the mouse to one of the dotted boxes for a second to see a small description of the sub-application. Select a sub-application and you can further narrow down the field of possible pump types based on default values of minimum free passage and usability within the selected sub-application. Select type of Installation Select type of installation by either clicking once on one of the illustrations and then clicking the Next button or simply by double-clicking on the illustration of the preferred type of installation. For all wastewater subapplications the main selection is between submerged or dry-installed pumps.

53 Configuration Specify how many pumps and standby pumps you need to get the required flow. Please note that if more than one pump is required, the result of the sizing calculation will contain pumps of the same type. However, in some sub-applications in the municipal wastewater application area you can choose to add a larger standby pump. Total number of pumps: Select how many pumps of the same size you want. In some sub-applications in the municipal wastewater application area you can even size a standby pump (bigger pump for heavy rains, flooding, etc.) Of these: number of standby pumps: Select how many standby pumps you want. Number of pumps minus number of standby pumps = number of pumps required to reach the specified flow. In later steps you can see the flow velocity and the performance curves for 1 pump, 2 pumps... or all pumps in operation. Select type of Hydraulic, Material and Motor

54 Depending on the application area and sub-application selected, the wizard contains steps for the selection of hydraulic design, materials and motor. At each step, select your preferences. This further narrows the range of available pumps. Your Requirements Enter your required flow and head values (discharge flow and geodetic head). CAPS now has all the information needed to present you with a list of pumps matching your requirements. Discharge Flow: Discharge flow is defined as the flow to be delivered by the system. If the calculator for assumed inlet flow is used, CAPS automatically adds a safety factor of 15% when converting this into discharge flow. Geodetic Head: Geodetic head is the actual physical difference in height between the average liquid level in the pit and the highest point of the discharge pipe (or average water level in the receiving vessel).

55 Pipe friction losses: Friction losses are defined as loss of pressure in the pipeline as well as from the various fittings in the pipeline. Different calculators for both friction losses and flow velocity in all possible situations are available. Allowed undersize: A flow rate x% below the required is accepted Calculators The wastewater sizing wizard offers a number of calculators to provide you with a guideline for the possible discharge flow and pipe friction losses. Calculating the discharge flow To calculate the discharge flow, click on the calculator next to the discharge flow input field. When opening the calculator for estimated inlet flow you get the option of calculating different kinds of inlet flow. In commercial buildings, sewage sub-application you will see two calculators, one for surface water discharge flow and one for wastewater discharge flow. The surface water discharge flow calculator requires a number of inputs: Selected area: Based on the risk of damage by heavy rain you can select either a flat or a mountainous type of area. Rated rainwater intensity is Flat = l/s/m2 Mountainous = l/s/m2. Roof area: The horizontal projection of the roof area.

56 Vertical area: Vertical surfaces are exposed to heavy showers. Vertical surfaces are typically walls pointing towards the prevailing wind direction. Catchment area: The horizontal projection of the catchment area. Type of catchment area: The quantity of rainwater that will reach the pit or collecting tank depends on the type of catchment area: Concrete: Discharge coefficient: 1.0 Gravel and grass: Discharge coefficient: 0.8 Gravel: Discharge coefficient: 0.6 Garden: Discharge coefficient: 0.1 Click OK and the calculator returns both an inlet flow and a discharge flow value incorporating a calculated safety margin of 15%. The wastewater discharge flow calculator enables you to estimate the wastewater flow according to the EN standard. All you have to do is define the type of building and enter the number of draw-off points: Typical frequency factors associated with different applications: Office or guesthouse: Frequency factor K=0.5 for intermittent usage

57 Hospital, school or hotel: Frequency factor K=0.7 for frequent usage Toilet and/or showers open to public: Frequency factor K=1.0 for heavy usage Laboratory: Frequency factor K=1.2 for special usage Calculating the pipe friction losses Click on the calculator to the right of the pipe friction losses input field. The calculation of friction losses consists of three calculations: Pipe friction losses in the pit, in the manifold and outside the pit. The first step is to select the pipe material used in the pit and for the manifold. Click the drop-down button and select your pipe material. Pipe friction losses in the pit To calculate the pipe friction losses in the pit, enter the data for the pipe system inside the pit. At the bottom of the window you will get a recommended (pipe) diameter based on the recommended flow velocity. If there is a pipe with a different diameter inside the pit you can add this in line B. The roughness of the pipe is based on your selection of pipe material. To calculate losses incurred from single resistances, please use the calculator in the Zeta column. Enter the number of single-resistance losses in your pipe system inside the pit in this window:

58 Pressure loss in the manifold calculator To calculate the pressure loss in the manifold, select diameter DN, connection type and expansion. Minimum and maximum liquid velocity (v min and v max) will appear as you select the various connections. The calculated pressure loss in the manifold will appear at the bottom of the window. Pipe friction losses outside the pit calculator To calculate the pipe friction losses outside the pit, enter the data for the pipe system outside the pit.

59 Enter the pipe length, select pipe material and pipe size. At the bottom of the window you even get a suggestion for a recommended pipe diameter based on the calculation of the flow velocity. Similarly to the pipe-frictionlosses-in-the-pit calculator, you can calculate the losses from single resistances in your system outside the pit by using the calculator in the Zeta column. If you want to change the pipe diameter, just add a pipe 2, 3, 4, 5, 6 or 7 and enter the characteristics of that particular pipe. You can check the flow velocity in the pipe for 1 to 6 pumps in operation by selecting the number of pumps in operation. When all the calculations are made, go back to the Your requirements-window. The Start sizing-button will now be active, and you can go straight to the sizing result by clicking this button. Operational Conditions Enter the data for your power supply in order to narrow down the number of recommendations. If you wish to make a calculation of life cycle costs, enter the basic data concerning energy price, calculation period and the pumps operating hours.

60 Hit list Settings Here you can choose a specific pump to be included in the hit list. If you do so you can compare an evaluation of the system using this pump against the best hit. Here you also select evaluation criterion for your hit list and limit the search to a specific pump type. Grundfos recommends Here is the result of the sizing wizard's calculations The left column in the window shows an input overview detailing the inputs entered at the different steps in the wizard.

Entering extra input here will ensure even more accurate and detailed sizing calculations and printout data. Saving and loading Settings in Sizing All the input that you make in a wizard, such as head, flow, a load profile, etc. can be saved using the "Save as" button. These settings can be reloaded again using the "Open" button. Default settings CAPS allows you to set and save your own default settings within each sizing wizard. When you mark the `Default Settings'-option in the `Save sizing input' dialogue, all your input in the sizing wizard, except for Flow and Head, will be reloaded the next time, you enter the sizing wizard. Pressure Boosting The Pressure Boosting sizing area is used to select pumps for commercial buildings, industrial plant service systems, municipal water supply and irrigation. Selecting the application area is the first step of the wizard

64 Select Subapplication The next step of the Pressure Boosting sizing concerns the selection of the sub-application. Each application area contains a number of sub-applications to make it easier for you to identify the application you want to size a pump for. Your Requirements At this step, the user can enter the Flow and Discharge pressure values, which are essential in the sizing process.

65 Besides Flow and Discharge Pressure, there are other settings in Your Requirements: Min and Max. liquid temperature: This input not only includes or excludes certain pump ranges; it also determines the choice of seal. Min. and max. inlet pressure: Here CAPS checks if the minimum inlet pressure, combined with the vapor pressure of the liquid at the maximum liquid temperature and the flow that was specified, is still within the NPSH limits. In other words, depending on the pump type, if the inlet pressure is too low, combined with a certain liquid temperature and flow, there is danger of cavitation. Therefore CAPS will exclude pump types with NPSH values that are not within this range anymore. This can cause wet runners to be excluded from certain selections. Allowed undersize: Include pump systems in the sizing result hitlist capable of a flow a few percent lower than the entered duty point. It is recommended to allow an undersize of 10 percent to avoid unilateral overdimensioning. Note! Once the Flow and Discharge Pressure values have been entered, the `Start sizing' button is activated and it is possible to get a recommendation. Control mode Select the control mode that is most suitable for your selected type of installation. By default, CAPS has selected the control mode most often used for the selected type of installation, but the user can always select another control mode. The available control modes are defined by the input, the user has made earlier in the wizard, so it is not possible to select a control mode that cannot be used for the selected type of installation. The user can also decide if a frequency converter should be included and if it should be integrated or external.

66 Load Profile An important feature in CAPS Sizing is the ability to provide an accurate calculation of energy consumption based on a given load profile. CAPS lets you select between different load profiles; the `Standard profile' is a heating pump profile, while the `Full load' profile sees the pump always operating at a fixed duty point. You can also define your own load profile by selecting `User profile' and edit the values in the input fields.

67 Configuration At this step you define you define the configuration of your system. In `Dimensions according to Standard', you can define if you want the sizing process to take a specific dimensioning standard into account. If you choose DIN 1988 rules such as reserve flow, maximum number of starts per hour, flow velocity etc. are taken into account. At `Total number of pumps' you can set a specific number of pumps or allow CAPS to select the best solution within a set range of pumps e.g. 1-4 in accordance with the selected evaluation criteria such as price or energy consumption or both. After selecting the number of pumps you want to size for, you can also enter a number of standby pumps if any. If a tank is required on the discharge side, then mark the checkbox. CAPS can either calculate the membrane tank size or you can enter the tank size manually. If applicable you can enter the size of an existing tank in the discharge pipe. You can the percentage value of the difference between the start and stop pressure by the ON/OFF band question. This is the bandwidth in which the installation will switch on and off to avoid constant starting and stopping of the installation. At the `Velocity limitation' question, you can decide if flow velocity changes should be taken into account. At the `Preferred products' question, you can decide if you want to size for booster sets or for pumps. Operational conditions

68 At this step, the user can set the operational conditions for the pump including frequency, phase, power supply and voltage. CAPS will take these conditions into account when a reaching a sizing result. Hit list settings At this step, the user can set hit list settings for the outcome of the sizing process. This is also the last step before the sizing result reached.

69 Limit search to..: This gives the user the option of pre-setting the outcome of the sizing process based on the inputs made previously in the sizing process. Include particular pump in hitlist: This gives the user the option of pre-selecting a specific pump to be included in the hitlist. This can be useful for comparing a known pump with the sizing result. Max. hits per product group: Set the number of hits allowed per product group Max. hits total: Set the total number of hits wanted in the hit list. Evaluation criterion: The order of the results after pressing the `Start sizing' button depends on the "Evaluation Criterion" settings. By default this setting will be set to `Price + energy costs', but it is also possible to order the results in the hit list by `energy consumption' alone. Energy price: Set the energy price used to order the sizing results in the hit list Calculation period: Set the number of years used in the Life Cycle Cost calculation Grundfos recommends This is the result of the sizing wizard's calculations.

Pump Design At the pump design step, you select the types of pump design applicable to your application as well as pump material and connection type. Control Mode Select the control mode that is most suitable for your selected type of installation. By default, CAPS has selected the control mode most often used for the selected type of installation, but the user can always select another

75 control mode. The available control modes are defined by the input, the user has made earlier in the wizard, so it is not possible to select a control mode that cannot be used for the selected type of installation. The user can also decide if a frequency converter should be included and if it should be integrated or external. Configuration At the configuration step, you can specify how many pumps and standby pumps you need to get the required flow. Please note that if more than one pump is required, the result of the sizing calculation will contain pumps of the same type. Electrical Data

76 At this step, the user can set the operational conditions for the pump including frequency, phase, power supply and voltage. CAPS will take these conditions into account when a reaching a sizing result. Hitlist Settings Here you can choose a specific pump to be included in the hit list. If you do so, you can compare an evaluation of the system using this pump against the best hit. Here you also select evaluation criterion for your hit list and limit the search to a specific pump type. If you wish to make a calculation of life cycle costs, enter the basic data concerning energy price, calculation period and the pumps operating hours.

78 Sizing - Renewable Energy Systems General The sizing tool is where Grundfos utilizes its long experience in pump design and application knowledge. This results in a very comprehensive, yet easy to use program that is almost always able to produce a suitable pump for your application. The sizing tool is divided in 8 main application area's that are again subdivided in sub application areas. Depending on which market or country CAPS is used, applications and sub applications can vary. Each application comes with its own specific question catalogue. An important feature of these question catalogues is the possibility to quickly select a pump using only basic input concerning Head and Flow, make advanced calculations with regard to energy consumption, payback periods, load profiles, cost of ownership etc. The Sizing Wizard, a quick tour The Sizing Wizard basics A sizing wizard is a guide intended to help the user narrow down and find the right product for his needs. The wizard contains a number of steps with each step consisting of questions relating to the application you wish to size a pump for. Adjust the values and settings to suit your preferences or simply enter your required Flow and Head values and start the sizing. However, some input fields are interdependent, so we recommend you to follow the order suggested in the program. Use the Next and Back buttons to navigate between the steps in the wizard. Click the Start sizing button. Calculations will be carried out on the basis of your input.

79 After a few seconds, a list of relevant pump solutions is displayed at the bottom of the screen, ranked in order of relevance. You can then access further details by double clicking your preferred pump solution. Click the button Some of the input fields have a button next to them. When you click the button, a sub-window will appear, allowing you to enter additional input or perform a calculation. Entering extra input here will ensure even more accurate and detailed sizing calculations and printout data. Saving and loading Settings in Sizing All the input that you make in a wizard, such as head, flow, a load profile, etc. can be saved using the Save as button. These settings can be reloaded again using the Open button. Default settings CAPS allows you to set and save your own default settings within each sizing wizard. When you mark the Use as default sizing input in the Save sizing input dialogue, all your input in the sizing wizard, except for Flow and Head, will be reloaded the next time, you enter the sizing wizard.

80 Renewable Energy Systems The sizing tool for renewable-energy based water supply systems is a guide on how to size SQFlex Solar, SQFlex Wind and SQFlex Combi systems. Select the desired application type by clicking the Solar system, Wind system or Combi system button, depending on whether you want your SQFlex system to be powered by solar energy, wind energy or a combination of both. In short, the sizing calculation in the SQFlex sizing tool works in such a way that, based on the location on earth, solar and/or wind data are found. Based on information about the installation conditions, of the wind turbine and/or solar modules and product data, - and cable losses we calculate how much power is delivered to the pump. Based on pump characteristics, head and pipe losses, we calculate how much water is supplied by the pump. All pump types are investigated.this is held against the requirements (water to system) and more panels are added (for solar and combi) if not enough water is supplied. Select subapplication At the first step, the user can select between Solar system, Wind system or a Combi System: Your Requirements At the Your Requirements step, the user enters the basic requirements for the system such as water volume, peak month and Head but also location and sun tracking. Water volume

81 The SQFlex system will be sized to meet the water volume requirement per day for a particular month (often the peak month during which the largest volume of water is required). Enter the water volume per day of the peak month. Peak Month Select the month related to your water volume requirement. Head Enter the head. By head is meant the total dynamic water level: The difference in height between the (lowered) water level in the borehole and the water level in the tank/reservoir. If you want more accurate calculations of cable and friction losses, click the calculator button. A number of calculators have also been added to assist the users. The Location and Sun Tracking calculators are based on data on solar radiation and wind speed, which are used in the sizing calculations to estimate the power available to the pump and thus the volume of water supplied. As solar radiation and wind speed depend on the installation location, input about the location are required in order to size an SQFlex system. Solar data (radiation and temperature) for more than 2000 locations are included in the sizing tool solar database. The wind database includes global wind data measurements (wind speeds and Weibull k factors at 10 m height and standard terrain conditions). Based on interpolations, an estimate of wind data can be found for any location in the world. The average temperature and altitude used for wind calculations are taken from the solar database. For a wind location, different from any of the solar data locations, average temperature is set to 25 C (77 F) as default and altitude from the last selected solar data location is maintained. Below the Location calculator is shown:

82 The Sun Tracking calculator is shown below: Here you can select mounting of modules: Fixed or with either single (polar) axis or double axis (full) sun tracking. The sizing tool will automatically select a basic orientation of the solar modules facing directly south/north, a tilt angle equal to the latitude as well as a reflection (surface) of 0.2 (grass dry). Via the calculator button, you can adjust the default settings and investigate how the adjustment affects the solar radiation available at the surface of a solar module. Irrelevant inputs will be removed or dimmed when you select

83 tracking. If you have selected fixed mounting, you can adjust the tilt angles for individual months via the table, if required. You can also see the solar radiation variation through the day of a specific month System Configuration In order for the accessories to appear on the printouts and in the price calculation, you can select them in the System Configuration step. The inputs will not affect the sizing of the system. Solar array support structure (Solar and Combi systems) Grundfos offers support structures for the GF solar module. If you do not require any support structures, deselect them here. Row closures and wire kits To mount the solar array support structures you need row closures and wire kits. The sizing program will automatically calculate how many you need and show it in the results and printouts. If you do not want any row closures or wire kits shown in the results deselect them here. Box Select control unit/switch box. User-defined Day The results calculated on the basis of average values for solar radiation and wind speed may show that no water will be supplied during a specific (winter) month. The User-defined Day function enables you to show your customer how much water the sized system will provide on a particular day of the specified month with a certain solar radiation and/or wind speed (higher than the average values). The inputs required for the calculation are solar radiation, month, temperatures and/or wind speed.

84 Solar radiation (Solar and Combi systems) Enter the daily solar radiation value (on a horizontal surface) for the user defined day. The solar radiation on the solar module surface is calculated on basis of input about sun tracking, tilt angle, basic orientation and reflection (surface) in the General section. Month (Solar and Combi systems) Select the month concerned. (When you do so, the number of sun hours and the sun s movement pattern will automatically be found in the calculations). Temperature (Solar and Combi systems) Enter the average daily temperature for the user-defined day at the location. The default value is taken from the database for the selected location and month of the user-defined day. Temperature variation (Solar and Combi systems) Enter the temperature variation (the average number of degrees between the average temperature and high or low temperature.). If you have a maximum value for the temperature you can take the max. temperature and subtract it by the average temperature. Wind speed (Wind and Combi systems) Enter the average (actual) wind speed value at the height of the rotor, you want for the user-defined day. (The entered value wil not be adjusted for roughness, hill and shelter effects.) Hitlist Settings Here you can choose a specific pump to be included in the hit list. If you do so, you can compare an evaluation of the system using this pump against the best hit. Here you also select evaluation criterion for your hit list and limit the search to a specific pump type.

You can also click on Alternatives to see other products that fulfill the input made during the sizing process.

87 Life Cycle Cost Calculations Life cycle cost analyses are useful in many situations and they can be of great help when you want to: - analyze the life cycle cost of the selected pump - choose a new pump solution - estimate whether or not it would be profitable to replace and old pump system - have documentation to support your decision. A life cycle cost analysis provides an estimate of the total cost of owning and operating a pump system. It covers the initial investment and operating costs, giving a much more accurate picture of the actual cost involved. All calculations and input is based according to the standards of Europump and the United States Hydraulic Institute. More information on these calculations can be found on these websites: Recommended literature on this subject is the publication Pump Life Cycle Costs, published by and available from these two organizations. Calculation in five steps Preparing a Life Cycle Cost analysis involves five steps. Note that you must follow the order of the five steps: 1. What to compare First, you indicate what you want to compare. You have up to five options: - no comparison - comparison with a pump in the hit list - comparison with a non-regulated pump (Heating & Air-Conditioning sizing only) - comparison with an existing pump - comparison with a pump in the hit list and an existing pump. 2. Level of detail You can select the level of detail you want in your Life Cycle Cost analysis. You may want simple or complete calculations, or perhaps you just want to compare energy consumption rates. In a simple analysis, Grundfos has pre-selected the most relevant parameters for you. In a complete calculation, all the parameters of the standardized LCC analysis are included. 3. General input At this stage, input is given for parameters, which are common for all pumps to be compared. This concerns inflation rate and interest rate.

88 4. Specific input You can now begin to enter specific LCC input for the pump systems to be compared. You can leave input fields blank if they are not relevant in your particular case. However the red dot by the `Pump System' input field indicates that this is a required input. The user must enter a value here to complete the Life Cycle Costs calculation. 5. Calculation Click the `Next' button. After a few seconds, you will receive the results. That's it. Five simple steps and you have a complete Life Cycle Cost analysis. How does the calculation work? First the Initial investment costs are evaluated, which are the pump price plus additional investment costs; added to this are the Installation and commissioning costs. These costs all occur only at the start of the pump life cycle Then the program evaluates the energy consumption (which is P1) and multiplies this with the operating hours per year, the energy prices and the Life in Years to come to the "Energy Cost". These energy costs are corrected for inflation rate and interest rate Added are the other yearly costs like: Maintenance cost Downtime and loss of production cost

89 Environmental cost At the end of the Life in Years (Pump Life Cycle) period the Net Present Value of the Decommissioning and Disposal Costs are calculated, corrected for inflation and interest rate. The point of this exercise is to prove that the initial investments are actually peanuts if the whole picture is evaluated and especially energy consumption is a major part. Also the program makes an evaluation of saving that can be achieved against an existing or an alternative solution. The Inflation Rate The inflation rate will actually increase the Net Present Life Cycle Cost value because it assumes that all costs will increase with this percentage per year. The Interest Rate This rate will decrease the Life Cycle Cost value because you can park your money that you have to pay in the years of the lifecycle on the bank against this rate. Note 1: The Inflation and Interest Rate are working opposite e.g. an inflation rate of 3% and an interest rate of 3% will eliminate each other and the outcome of the calculation of the Life Cycle Cost will be the same as if in both fields nothing was filled in. Note 2: Operating hours per year It would be expected that if the pump operates for instance 10 hours per day and 360 days per year, the yearly operating hours would be However WinCAPS makes an intelligent evaluation of the requested dimensioning flow and the actual calculated flow and will adjust the number of operating hours accordingly. So with a higher actual flow, the number of operating hours will be decreased to come to the requested yearly cubic meters. Where can I see the result of the Life Cycle Costs calculation? After completing a Life Cycle Costs calculation, you can make a print-out containing a table and a graphical representation of the result. Click the print icon and select the `Life Cycle Cost report - graphics' and `Life Cycle Cost report - table' options in the Print/Preview dialogue.

90 Click the `Preview/Export' button to see the print-out: The `Life Cycle Cost report - graphics' print-out

91 The `Life Cycle Cost report - table' print-out: After a Life Cycle Cost calculation is completion, the result of the Life Cycle Cost analysis can also be seen in the `Life Cycle Cost'-tab. Simply click on the product in the hit list and then click on the tab to get both a graphical representation of the result as well the table containing the calculated results.

92 Additional sizing options Sizing Summary print The Sizing summary print option is a new feature in CAPS. This printout contains the most important input and sizing results using graphics and colour to provide an immediate overview of the results of the sizing calculation. In many cases this is all the documentation you need.

93 Service General From version 7.5 the service information has been greatly enhanced, offering interactive exploded views and sectional drawings for most Grundfos products.

96 Replacement General The replacement section is divided in several sections, which are accessible by the drop down list on top of the screen Central heating and hot water circulation pumps CAPS contains a comprehensive replacement list for central heating circulating and hot water pumps. You will access this list by pressing the "Replacement" on the top of the screen. After selecting the manufacturer of the pump you want to select, you can make a pre-selection by typing in a type-designation, pipe connection or by built in length Depending on local availability, distance pieces are also included if the existing pump has a longer built-in length then the new pump. Should there be special conditions to be taken into account with replacement, these are displayed when pressing the "Information" button in the left hand bottom corner. Grundfos CR replacement program CAPS includes a comprehensive replacement program in which the old Grundfos CR series can be replaced by the new CR models. Just follow these simple steps: * Select the type of CR pump you want to replace. Include the flow for reference purposes * Select a pump from the list of old CR pumps that are applicable for these conditions * After clicking on one of these particular pumps, the hit list will appear with suitable replacements * Clicking on the "i" will pop up a screen with relevant replacement information

97 Double-clicking in the hit list will show the graph with the pump curve of the old pump compared to the one of the new pump. Your requested flow is displayed on the old pump curve. Old and new pump curve in 1 graph Grundfos is continuously updating the replacement program with new pump series and new competitors

98 Selecting Accessories General CAPS comes with a range of standard accessories that can be selected either with a pump or separate. A distinction is made between electrical and mechanical accessories. All Grundfos pump controls and accessories to those controls are in the electrical section while flanges, couplings, pipes, tanks etc are in the mechanical part. If you want to select accessories with a pump, first choose your pump in Catalogue or Sizing. Click on the "Accessory" button in the bottom left hand corner and the accessories for your selected pump series become available, including (when available) drawings, instruction manuals, photo's etc. After selecting an accessory, the details will be displayed on the right hand side of the screen, while the pump details will still be visible on the left. If you want to select an accessory without selecting a pump first, you can only do this from the Catalogue area. When going into the Catalogue area, there will be a book in the bookshelf that contains the accessories. From this book you can make your selections.

99 Working with Glycol solutions and solutions other than water General CAPS offers the possibility to adapt the pump curve and the power consumption according to the kinematical viscosity and density of the pumped fluid in relation to the temperature of the fluid. In the Catalogue you can simulate the fluid by pressing on the calculator button in the "Curve settings" menu. The steepness of the curve will change and where the power of the installed motor is insufficient, the curve will be dotted. Extensive possibilities for Glycol type selection. In sizing, there is the possibility in the "Advanced" sections of Heating and Air-conditioning to select glycol in the "Pumped Liquid" field, allowing input for type, concentration, temperature etc. After entering the new data in the fields Viscosity and Density, CAPS will calculate the new pump curve and power consumption. Important. This new data might lead to a selection of a bigger pump than if you would select a pump using Heating water as a medium. The reason is that CAPS detects that the installed motor of the original selection (using Heating water) will not cover the entire curve anymore if you use glycol and will select a standard pump with a bigger motor, e.g. 15 kw instead of 11 kw). Important: While the above is technically correct, in practice often the smaller pump is preferred but with an oversized motor. In this way the better duty point is combined with the ability to cover the entire curve and often a smaller pipe connection will suffice. The reason that CAPS chooses the bigger pump solution is because the program does not (yet) contain any data of standard pumps with oversized motors. If glycol is selected with a minimum liquid temperature under 0 C, CAPS automatically searches for a pump with the correct seal. (this function depends on local availability of pump types with the correct shaft seal).

100 When changing the density and viscosity, CAPS also still display the original pumpcurve in the background and indicate when the motor is overloaded Working with Non Newtonian Liquids The calculations for different viscosities in CAPS are based on Newtonian liquids and cannot be used for non- Newtonian liquids. Grundfos should be contacted in case you want to pump solutions that fall under that category Non-Newtonian liquids are liquids with a nonlinear relationship between shear rate and shear stress. This means that the viscosity is not constant but will change with head and flow rate. The behaviour of non-newtonian liquids will not only change with head and flow, but will also be different for different types of liquid. Examples of non- Newtonian liquids are: Paper pulp, grease/oil, soap and paint. Antifreeze/Secondary fluids for heat transfer included In WinCAPS 7.43 new medias were introduced to ease the use of CAPS when working with antifreeze or secondary fluids. The list of fluids is constantly expanded; check your CAPS version for the current list In connection with the implementation of the new fluids, new functionality has been added to both the Catalogue and the Sizing part of CAPS. Medium selection in the Catalogue When a pump is selected and the "Curve Settings" button is clicked, a calculator button appears beside the input fields for Viscosity and Density. If the button is used, a dialogue box appears, where you can select a liquid from the dropdown list and, depending of which media you have selected, input your concentration and Liquid Temperature during operation. When this is selected, CAPS automatically calculates the Viscosity and Density for you. The calculation of density and viscosity based on concentration is supported by Department of Mechanical Engineering, Energy Section, Technical University of Denmark.

101 NOTE: If an Antifreeze media is chosen in Catalogue, it is not checked whether or not the pump is suitable for the media. This feature is only applied in the Sizing part of CAPS. If you select a "Liquid temperature during operation" that is below the minimum temperature that your concentration of the media would allow, CAPS input "zeros" in both Viscosity and Density thus making it impossible to calculate a new curve with the not allowed values. The limitation for Viscosity is mm/s while for Density they are kg/m. Inputting numbers that result in values outside these limitations will provoke an error message and stop a corrected curve from being calculated and shown. NOTE: Some pumps are allowed to appear in the hit list even though they do not fulfill all the rules above. These are pumps where you can easily change the shaft seal to a suitable type for the fluid. When ever such a pump appears, the sizing result will contain a yellow frame with a warning that request the user to change the shaft seal - and contact Grundfos.
