Energy-saving vertical multistage centrifugal pump for large buildings.

Enquire About This Product

Description

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.
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
