Wilo-Multivert MVIE

Energy-saving vertical multistage centrifugal pump for large buildings.

Wilo-Multivert MVIE (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.
