Description
Wilo-Multivert MVIE (11-22 kW) is a vertical multistage variable-speed pump for cold water applications in large buildings. The pump consists of 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. High reliability is ensured by the proven pump hydraulics made of stainless steel, a separate lantern ball bearing that ensures optimum absorption of axial thrust, integrated protective functions and low-water detection.
Simple integration into building automation is made possible via analogue and digital interfaces as well as IF modules.
