KRS Series – Submersible Drainage Pumps
Max Flow Rate: 200L/sec (12m3/min)
Head Max: 35m
Efficient drainage for construction, and industrial applications
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.
| Discharge Bore(mm) | 80 – 250 |
|---|---|
| Motor Output(kW) | 2.2 – 22 |
Features
- Top discharge, side flow design channels liquid around the motor to provide cooling, enabling reliable low-water-level operation over extended periods (excludes KRS1022)
- Ductile cast iron semi-open impeller
- Flange connection
- Tsurumi’s exclusive oil lifter device, and dual silicon carbide mechanical seals
- Anti-wicking cable entry system prevents water ingress, protecting internal components
Typical Applications
- Civil infrastructure projects (road, rail, dam, and bridge)
- Construction work
- Rainwater drainage
- Flood control
