Highly efficient high-pressure multistage centrifugal pump in vertical design with in-line connections.

The non self-priming high-pressure multistage centrifugal pump has a particularly compact overall design. The pump shaft and the motor shaft of the IEC standard motor are connected by means of a clamp coupling. A separate lantern roller bearing ensures optimum admission of axial thrusts.

Intermediate bearings in the hydraulics and corrosion-resistant shaft due to stainless steel sleeve ensure a long service life.

The pump housing and lantern are cataphoretic-coated.

Special, permanently attached lifting eyes enable easy pump installation.

The pump is suitable for water distribution and pressure boosting, industrial recirculation systems, process water and closed cooling circuits. It can also be used in fire extinguishing systems, washing systems as well as for irrigation.

  • Efficiency-optimised, laser-welded 2D/3D hydraulics
  • Corrosion-resistant impellers, guide vanes and stage housings
  • Flow and degassing-optimised hydraulic parts
