Product Description
The cast iron construction of our KRS series extends pump life by preventing premature wear and failure from the abrasive materials found in mining, aggregate, and construction applications. Available in a variety of discharge sizes and horsepower, the KRS pumps are engineered to withstand even the most rigorous situations.
Discharge sizes from 3-14 inches and horsepower ranges from 3-50 hp.
4 pole, 1800 rpm motors reduce impeller tip speed and extend parts wear life.
Rugged cast iron construction holds up to the most aggressive mining, aggregate, construction applications.
Dual Silicon Carbide Mechanical seals in a separate oil bath.

Pump for Sewage Bypass Model KRSU
Pump for Sewage Bypass
Discharge Bore(mm) 200
Motor Output(kW) 22
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 foreign matter. The top discharge, side flow design assures efficient motor cooling even when operating with the motor exposed to air.
KRS Dewatering Pumps
Dewatering Pumps
Discharge Bore(mm) 80 – 250
Motor Output(kW) 2.2 – 22
The KRS-series is a submersible three-phase cast iron high volume heavy-duty drainage pump driven by a 4-pole motor. The cast iron body, combined with the low speed motor, presents extra durability for use in the most demanding conditions. The top discharge, side flow design assures efficient motor cooling even when it operates with its motor exposed to air.*
* Model KRS1022 is a top discharge, flow-thru design. The top discharge, flow-thru design provides maximum motor cooling efficiency allowing continuous operation at low water levels and extended dry-run capability.
