KRS/KRD Series – Submersible Slurry Pumps
Heavy-duty slurry pumping for mining and construction applications
The KRS/KRD-series of slurry-handling type is a submersible three-phase cast iron heavy-duty slurry pump driven by a 4-pole motor. It is equipped with a high-chromium cast iron agitator that assists smooth suction of the settled matters. The other wear parts such as the impeller and the suction plate are also made of high-chromium cast iron for extra durability. The top discharge, side flow design assures efficient motor cooling even when it operates with its motor exposed to air.
| Discharge Bore(mm) | 80 – 200 |
|---|---|
| Motor Output(kW) | 5.5 – 18 |
Features
- High-chromium cast iron agitator breaking up settled sludge and keeping solids in suspension
