12 General Data Pumed Liquids Thin, non-exlosive liquids, not containing solid articles or fibres. The liquid must not attack the um materials chemically. When uming liquids with a density and/or viscosity higher than that of water, motors with corresondingly higher oututs must be used, if required. Whether a um is suitable for a articular liquid deends on a number of factors of which the most imortant are chloride content, value, temerature and content of solvents, oils etc. Please note that aggressive liquids (e.g. sea water) may destroy the oxide film which rotects the stainless steel and thus cause corrosion. CR, CRN For liquid transfer, circulation and ressure boosting of cold or hot clean water. CRN In systems where all arts in contact with the liquid must be made of stainless steel, CRN ums must be used.

The curves aly to a kinematic viscosity of υ = 1 mm /s (1 cst). 5. Due to the risk of overheating, the ums should not be used at a flow below the minimum flow rate. The curve below shows the minimum flow rate as a ercentage of the nominal flow rate in relation to the liquid temerature. Qmin [%] t [ C] TM

16 Dimensioning Vertical Multistage Centrifugal Pums Selection of CR, CRN Pum Pum Size Selection of um size should be based on: consumtion attern, highest ossible flow and ressure (eak values), economy. As a rule of thumb ies should be dimensioned in such a way that the velocity of the liquid does not exceed 1 to 1.5 m/sec Q [m³/h] TM Efficiency If the um is always to oerate in the same duty oint, select a um where this duty oint coincides with the highest efficiency. In case of controlled oeration or varying consumtion, select a um whose highest efficiency falls within the duty range reresenting the highest ower consumtion, i.e. tyically the duty range covering the greater art of the duty time. NPS If the ressure in the um is lower than the vaour ressure of the umed liquid this may cause cavitation. To avoid cavitation, make sure that there is a minimum ressure on the suction side of the um. The maximum suction lift in metres head can be calculated as follows: = b x 1. NPS f v s b = Barometric ressure in bar. (Barometric ressure can be set to 1 bar). In closed systems, b indicates the system ressure in bar. NPS = Net Positive Suction ead in metres head (to be read from the NPS curve on at the highest flow the um will be delivering). f = Friction loss in suction ie in metres head (at the highest flow the um will be delivering.) v = Vaour ressure in metres head. s = Safety margin = minimum.5 metres head. If the calculated is ositive, the um can oerate at a suction lift of maximum metres head. If the calculated is negative, an inlet ressure of minimum metres head is required. The um must be able to fulfil the flow and ressure requirements. Eta [%] Q [m³/h] Check that the highest efficiency falls within the marked duty range. f Pb v NPS Check that the um does not have and will not be exosed to cavitation. tm ( C) ,, 5,, 3,, 1,5 1,,8,,,3,,1 v (m) TM1 398 TM TM

17 Dimensioning Vertical Multistage Centrifugal Pums Material The material variant (CR/CRN) is to be selected on the basis of the liquid to be umed. The roduct range covers two basic tyes. CR is suitable for clean, non-aggressive liquids such as otable water, oils, etc. CRN is suitable for clean, slightly aggressive liquids such as salt water, acids, etc. (see list of umed liquids age ). Shaft Seal The shaft seal is to be selected on the basis of liquid temerature and max. ressure. For other liquids than water, the chemical resistance of the materials - incl. seal face, seat and rubber comonents of the shaft seal - must be taken into account. Parallel Oeration It may be an advantage to install a number of ums connected in arallel instead of one big um. Among the advantages are for instance: adatation to the required duty oint in systems with varying flow rofile, increased reliability of suly as only art of the system caacity is affected in case of um failure. Miscellaneous In case of liquid viscosity and relative density different from that of water, motor size and um erformance must be taken into account. The material variant must be suitable for the umed liquid (CR or CRN). [bar] t [ C] The shaft seal material and variant must be suitable for the umed liquid Q [m³/h] In case the duty rofile varies, consider the installation of two or more ums in arallel. TM TM1 398 TM
