pumps and pumping systems  
 
 

Single-stage, centrifugal monoblock pumps type MVA, MVB

Application

Th e MVA and MVB pumps are used for pumping low-viscosity nonfl ammable non-explosive liquids which are clean or contain only trace amounts of impurities.

The MVA and MVB pumps find application in:

  • water supply systems and water mains,
  • pressure boosting systems
  • boiler feedwater systems and condensing boiler systems
  • air-conditioning, central heating and water circulation systems
  • industry
  • fi re-fi ghting systems

Discharge fl ange DN 32 ... DN 150 mm

* You can use motors above 55kW - please contact us technical department

Th e MVA and MVB series are single-stage, centrifugal, suction, monoblock pumps where the impeller and pump share the same shaft.
Main dimensions and rated parameters conform to EN 733 (previously DIN 24255). Suction and discharge fl anges comply with ISO 7005-2/PN 16.
MVA and MVB pumps are directly connected with electric motors which comply with VDI and IEC standards. Due to special modular design, the motor, sealing cover and impeller can be removed without the need to dismantle the volute casing.
The MVA and MVB monoblock pumps are lighter and smaller when compared to the normal centrifugal pumps of similar hydraulic performance.
