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 applications 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
  • IE5 EC motor and typical control functions for energy efficiency (11 – 22 kW)
  • Suitable for integration into building automation systems via analogue and digital interfaces and IF modules ​
  • Proven pump hydraulics in stainless steel, thrust bearing, integrated protection functions and low-water detection ensure high reliability​
  • Special, built-in lifting eyes facilitate simple pump installation
