KRSU Series – Submersible Drainage Pump
Max Flow Rate: 95L/sec (5.7m3/min)
Head Max: 27m
Heavy-duty pump for bypassing drainage in sewer construction work
The KRSU822 pump of submersible three-phase cast iron heavy-duty pump is designed and built specifically for temporarily bypassing drainage in sewer construction work. With a maximum head of 26.5 m, maximum capacity of 5.7 m3/min, and space-saving design of 546 mm in diameter, this pump plays an active role in drainage in the deep confined space of a manhole.
Also, with its semi-vortex structure, this pump provides a large solids passage of 56 mm in diameter, which prevents any clogging of solids matter. The top discharge, side flow design assures efficient motor cooling even when operating with the motor exposed to air.

Submersible Sewer Bypass Pumping
Since sewage piping suffers from aging-related deterioration and can be damaged by earthquakes, sewage piping requires repairs and replacing at regular intervals. In sewage piping repair work, consideration should be given to area residents inconvenienced by the repair work, and additionally to work efficiency and the safety and health of workers who handle inflow sewage. For this purpose, provisional draining that temporarily bypasses sewage via a pump is extremely effective.
As a pump for bypassing sewage between manholes in sewage piping renewal work, Tsurumi offers the KRSU822 pump of submersible sewer bypass pump. This pump features a maximum head of 26.5 m, a maximum capacity of 5.7 m3/min, and a compact space-saving design of just 546 mm in diameter. Normally, with engine pumps, it is difficult to suck up fluid from a depth of 7 m or more, but the KRSU submersible pump can fit in the deep limited confines of a manhole and there play an active role in draining the manhole. In addition, with its semi-vortex structure, this pump provides a large solids passage of 56 mm in diameter, which prevents clogging of solids matter. In fact, it is particularly effective towards preventing clogging of fibrous solids in the impeller, which is the biggest problem in draining sewage. The stand has a bottom plate structure so that the pump can stably stand by itself even when the pump is placed on earth, sand or sludge. The KRSU822 has a top discharge, side flow structure that effectively cools the motor even when the pump runs with the motor exposed to air. Thus, the KRSU822 is highly suited as a bypass pump.
