4 Submersible Vertical Electric Pumps SVI Series MARKET SECTORS INDUSTRIAL, CIVIL APPLICATIONS Pumping of coolants, lubricants and condensate. Machine tools, welders, engine test stands. Cooling systems. Washing systems. Boosters. Fire-fighting systems. SPECIFICATIONS PUMP Delivery: up to 72 m 3 /h. Head: up to 250 m. Liquid temperature: -10 C to +90 C for S and N versions with coupling, -10 C to +60 C for close-coupled E versions. Maximum ambient temperature: +40 C. Tested in compliance with ISO 2548 for class C standard pumps. Rotation direction: clockwise when looking at pump end (indicated by the arrow on adapter and coupling). Mechanical seal in compliance with DIN and ISO 3069 for S and N versions, LOWARA seal for E versions. Tank coupling flange in compliance with DIN 5440 and EN Standard installation in vertical position: however, all models (except the SVI 30 and 60 versions with over 5 stages at 50 Hz, and with over 4 stages at 60 Hz) can be installed horizontally. Reduced axial thrust allows standard motors to be used (for S and N versions). These pumps can handle clean liquids free of abrasive substances or fibres, with kinematic viscosities up to 37 mm 2 /sec., with suitably sized motor. Minimum level of suction liquid: 25 mm for SVI models and 100 mm for SVI 30 and 60 models. Suction base has filter with 2 mm. diameter holes (SVI 2-4) or 3 mm. holes (SVI ). AISI 316 STAINLESS STEEL N version available for models SVI Longer pump columns (from coupling flange to suction base) are available on request. Possible variants follow the number of upper stages indicated in each model s dimensions table. MOTOR Squirrel cage, finned aluminium casing, enclosed construction with external ventilation. IP55 protection. Class F insulation. Performance in compliance with CEI 2-3 (IEC 34.1). Construction design: Close-coupled for E version (LOWARA motor); Standard motor for S and N V18 versions, for power up to 4 kw, and V1 versions for power above 4 kw. Standard voltage: Single-phase V - 50 Hz on request. Three-Phase / V - 50 Hz with power up to 3 kw; V - 50 Hz with power above 3 kw. 4

46 Hydrovar frequency converters APPLICATIONS Pressure regulation in the water systems of civil, residential and industrial buildings. Handling of liquids in air conditioning systems where it is necessary to boost pressure in pipes with excessive flow resistance. Water treatment and process engineering for constant delivery when pressure variations occur. SPECIFICATIONS Single phase models: Hydrovar HV 2/.. Series Power: 1,5 2,2 kw. Mains voltage U: 1x230 V ±15%, Hz Motor voltage U1: 3x230 V Hz Three-phase models: Hydrovar HV 3/.. series Power: 2,2 22 kw. Mains voltage U: 3x400 V ±15% Hz Motor voltage U1: 3x400 V Hz Ambient temperature from 5 C to 40 C. 50% humidity at 40 C. IP 54 protection. Built-in anti-condensation device. Designed to connect up to 4 Hydrovars. Individually interfaceable with a computer through an RS485 system. Display with directions in 7 selectable languages. 46

47 THE TECHNOLOGY CONTROL AND REGULATION The HYDROVAR integrated frequency converter features automatic regulation of the number of revolutions of an asynchronous three-phase electric motor, by interpreting either a pressure or a differential pressure or a delivery signal (Fig. 1 and 2). A patented control system disconnects the pump in case of a decrease in user demand. The pump delivery is detected indirectly through the number of revolutions, enabling the pressure, or the differential pressure, to be regulated according to the rate of consumption, based on the pre-set system characteristic parameters (Fig. 3). REGULATION BASED ON CONSTANT PRESSURE Fig. 1 Besides the autonomous regulation possibilities described above, the pump with the HYDROVAR device can also be connected to an external system on which the regulation parameters must be set. The HYDROVAR device is equipped with connection terminals for remote start and stop, for operating and malfunction signals, and for the transmission of an analogue signal (speed or actual value of the regulation signal) to a central control station. It is also equipped with an RS 485 interface connection for communication with a central process control system. REGULATION BASED ON CONSTANT DELIVERY Fig. 2 To prevent access and tampering by unauthorized personnel, the set parameters can be partially or fully protected by password. The activation or deactivation of the pump and the setting of the required parameters are obtained directly through the command keys, with messages appearing on the frequency converter s LCD display. Three differently coloured diode indicator lights signal ON, RUN and FAULT (Fig. 4). Seven different languages can be selected for the information appearing on the display. In case of coupled systems, the microprocessor contained in each regulation unit automatically controls the pumps sequential operation based on system requirements. It also controls their cyclic connection in series and automatic switch in case of malfunction, without requiring any supplementary control devices. The frequency converter supplies a sinusoidal evaluation output voltage, modulated by impulse length. It operates with controlled synthesis of the sinusoidal current and dynamic current limitation. The high 8 khz impulse frequency prevents the development of undesired motor noise. With the harmonic filter any reactions in the low voltage areas are avoided (in compliance with EN 55011/91, cl.b). The cooling of the frequency converter is ensured by the pump motor fan or, in the wall-mounted version, the fan located in its base. REGULATION BASED ON SYSTEM CHARACTERISTICS Fig. 3 Fig. 4 47
