Wilo-Helix VE

Energy-saving vertical multistage centrifugal pump for large buildings.

Your advantages
Wilo-Helix VE

Energy-saving vertical multistage centrifugal pump for large buildings.

Wilo-Helix VE (11-22 kW) is a variable speed vertical multistage pump for cold water application in large buildings. It combines an IE5 EC motor drive, an integrated, air-cooled frequency converter and various control modes. The result is high energy efficiency in both closed and open systems.​

Proven pump hydraulics in stainless steel, a separate lantern roller bearing that ensures optimum admission of axial thrusts, integrated protection functions and low water detection allows high reliability. ​

An easy integration into building automation is possible thanks to analogue and digital interfaces and IF modules.
