The KRS2-series, recently renamed to KRD 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.
