SVI – Submersible vertical electric pumps

The submersible vertical electric pump SVI is a vertical-axis pump with submersible body, equipped with standard motor (for S and N versions).


MARKET SECTORS: INDUSTRIAL, CIVIL.


APPLICATIONS 

  • Pumping of coolants, lubrificants and condensate.
  • Machine tools, welders, engine test stands.
  • Cooling systems.
  • Washing systems.
  • Boosters.

SPECIFICATIONS

PUMP

  • Delivery: up to 120 m3 /h.
  • Head: up to 240 m.
  • Liquid temperature for the standard versions:

– from -10°C to +90°C for S and N versions with coupling.

– from -10°C a +60°C for close-coupled E versions.

  • Maximum ambient temperature: +40°C.
  • Mechanical seal Mechanical seal in Ceramic/ Carbon/FPM for the close-coupled E version and in Silicon Carbide/ Carbon/FPM for S and N versions with coupling. For SVI 33-46-66-92 models, mechanical seal can be replaced without removing the motor from the pump.
  • Tank coupling flange in compliance with EN 12157 (ex DIN 5440) for SVI 2-4 models.
  • Standard installation in vertical position; horizontal installation on request.
  • These pumps can handle clean liquids free of abrasive substances or fibres, with kinematic viscosity up to 37mm2 /sec, with suitably sized motor.
  • Minimum level of suction liquid: 25 mm for SVI 2-4-8-16 models and 80 mm for SVI 33-46-66-92.
  • Base in the suction side with filter in order to avoid damages due to solids entrance.
  • Tested in compliance with ISO 9906 Annex A.
  • Direction of rotation: clockwise look- ing at the pump from the top down (marked with an arrow on the adapter and on the coupling).
  • Longer pump columns (from coupling flange to suction base) are available on request. Possible variants are indicated in each model’s dimensions table.

MOTORS

  • 2 poles motors with squirrel cage in short circuit, enclosed construction with external ventilation.
  • Construction design:

– Close-coupled for E version.

– Standard motor for S and N versions.

  • Standard supplied IE2/IE3 motors are compliant with Regulation (EC) no. 640/2009 and IEC 60034-30.
  • IP55 protection.
  • Class 155 (F) Insulation.
  • Performances according to EN 60034-1.
  • Standard voltage:

– Three-phase version: 220-240/380- 415 V, 50 Hz for power up to 3 kW, 380-415/660-690 V, 50 Hz for power above 3 kW.
