Submersible pump TSURUMI U Series is a 2-pole-motor-based, compact type submersible vortex pump designed for handling raw sewage, wastewater and liquid carryingsolid 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.
Submersible pump TSURUMI U Series Featuring a vortex impeller recessed in the widely opened pump casing interior, the U and UZ pumps can handle sewage with large solids without clogging or winding.

– Copper wound motor, air-filled and rated for continuous duty
– Class F insulation
– Circle Thermal Protectors (CTP) provide protection due to excessive heat build up, over current, or electrical/mechanical failure
– Cast iron construction
