U


Pumps with Vortex Impeller

Discharge Bore(mm) 40 - 80
Motor Output(kW) 0.25 - 3.7

The U-series is a 2-pole-motor-based, compact type submersible vortex pump designed for handling raw sewage, wastewater and liquid carrying solid matters and fibrous materials. Rotation of the impeller produces vortex flow in the pump casing, which allows those foreign matters to be pumped out with minimum contact to the impeller. Since this mechanism does not require the foreign matters to pass through the impeller vane, the pump offers practically unchokable pumping.
