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.



Your advantages

  • Multistage, stainless steel, high-efficiency pump with adjustable speed, 2D/3D hydraulics and standard motor
  • Optimised design for easy operation, transport and installation with handles, lantern adjustment and rotatable loose flanges
  • User-friendly display with Green Button Technology and full-text menu
  • IF plug-in module for quick communication with the BMS
  • Innovative cartridge mechanical seal and spacers allow for quick maintenance
  • The new Helix design reduces life cycle costs
