KRS (Energy-Saving) Series – Submersible Drainage Pumps
Energy-efficient high-volume dewatering pump for drainage applications
The KRS-series is an energy-saving submersible three-phase cast iron, high volume, heavy-duty drainage pump driven by a 4-pole motor. It consumes less energy than the standard KRS-series at lower head applications. 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.
| Discharge Bore(mm) | 100 – 200 |
|---|---|
| Motor Output(kW) | 3 – 9 |
Features
- Includes a low-speed motor; low output and low head that reduce power consumption
- Flange connection
- Anti-wicking cable entry system prevents water ingress, protecting internal components
- Tsurumi’s exclusive oil lifter device, and dual silicon carbide mechanical seals
- Top discharge, side flow design channels liquid around the motor to provide cooling, enabling reliable low-water-level operation over extended periods
Typical Applications
- Civil infrastructure projects (road, rail, dam, and bridge)
- Construction work
- Rainwater drainage
- Flood control
