The KRSU822 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.
