The UT-series is an economical type submersible vortex pump designed for handling raw sewage and wastewater from domestic and commercial areas.

Rotation of the impeller produces vortex flow in the pump casing, which allows solid matters and fibrous materials to be pumped out with minimum contact to the impeller. Since this mechanism does not require those foreign matters to pass through the impeller vane, the pump offers practically unchokable pumping.
