Wilo Helix V616-1/25/E/KS/400-50, Pressure Boosting Pump

Highly efficient pressure booster pump in vertical design with inline connections.

Description

The normal-suction booster pump has a compact design and is easy to maintain. The connection to the pump shaft and the shaft of the IEC standard motor is made with a sleeve coupling. A separate lantern roller bearing ensures optimal absorption of axial force. Intermediate bearings in the hydraulics and corrosion-resistant shaft with stainless steel sleeve guarantee a long service life. Special, permanently mounted lifting eyes make the pump easy to install. The pump is suitable for use in water supply and pressure boosting, in industrial circulation systems as well as in process water circuits and closed cooling circuits. It can also be used in fire extinguishing systems, laundry facilities and for irrigation.
