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 compact overall design and is particularly efficient and easy to maintain. The pump shaft and the motor shaft of the IEC standard motor are connected by means of a clamp coupling, while 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.

The pump is suitable for water supply, 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.

Special features/product advantages

Efficiency-optimised, laser-welded 2D/3D hydraulics, flow and degassing optimised
Corrosion-resistant impellers, guide vanes and stage housings
Flow and NPSH-optimised pump housing
Maintenance-friendly design with particularly robust coupling guard
Drinking water approval for pumps with parts that come in contact with the fluid made of stainless steel (EPDM version)

Scope of delivery

Wilo-Helix V high-pressure multistage centrifugal pump
Installation and operating instructions

Design notes

Motor protection for 3-phase motor is to be provided on request or onsite
Single-phase AC motor equipped with built-in thermal motor protection and capacitor
In its standard position, the terminal box is aligned with the suction flange, but this can be changed if necessary
