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
