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 *Reinforced pump housing, flow and NPSH optimised *Space-saving and easy maintenance due to the compact design *Particularly sturdy coupling guard Scope of delivery *Wilo-Helix VF or Wilo-Helix FIRST VF high-pressure multistage centrifugal pump *Installation and operating instructions *PN16 version with oval flanges: stainless steel counter flanges with the corresponding screws, nuts and gaskets for Wilo-Helix VF and cast iron counter flanges for Wilo-Helix FIRST VF
