Description

Dewatering Pumps

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.

Temporary Bypass during Dam Renovation

The dam that has been subjected to a renovation is a multipurpose dam to support the water source for agricultural, industrial, and household water. It is an important facility to the local economy. As more than 30 years have passed since the construction, it has to be renewed to a new system.

The project must ensure that every pump continues pumping water from the dam during the renovation of the main sluice gate. Tsurumi submersible general dewatering pumps, 22 units of KRS822L, were adopted for this significant role. These pumps were kept running continuously for 3 months, and the construction was successfully completed.
