Technical data
Tender text

Highly efficient high-pressure multistage centrifugal pump in vertical design with in-line connections, VdS certified for use as sprinkler pump in stationary water extinguishing systems.

Basis of VdS approval:

  • VdS 2344:2014-07
  • VdS 2100-07:2013-05

The VdS approval No. is P 418007

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. Special, permanently attached lifting eyes enable easy pump installation.

Special feature and product advantages

  • VdS certification as sprinkler pump (above ground) in stationary water extinguishing systems
  • Efficiency-optimised, laser-welded 2D/3D hydraulics
  • Corrosion-resistant impellers, guide vanes and stage housings
  • Flow and degassing-optimised hydraulic parts
