GSD Series – Submersible Slurry Pumps
Max Flow Rate: 191.6L/sec (11.5m3/min)
Head Max: 40m
Heavy-duty slurry pumping for mining and large-scale construction applications
The GSD-series is a high-powered heavy-duty slurry pump that delivers high head and high volume discharge. It is designed and built for continuous operation under the rough conditions often found at large-scale construction sites and mines.
The GSD is equipped with a high-chromium cast iron agitator to ensure smooth sediment intake and employs a mouth ring and impeller of same material to provide extra durability. Moreover, performance drop due to wear has been minimized by pairing a closed impeller configuration with Tsurumi’s unique mechanism that continuously adjusts the clearance between the mouth ring and impeller. The reliability in extended use has been improved with seal pressure relief ports that release pump pressure applied to the mechanical seal. The pump is additionally designed for side discharge via a spiral path that ensures the passage of solid matters. And, the motor is wrapped in a water jacket that keeps the motor cool during extended operation at low water level.
| Discharge Bore(mm) | 200 – 250 |

| Motor Output(kW) | 37 – 75 |
Features
- High-chromium cast iron agitator breaking up settled sludge and keeping solids in suspension
- High-chromium impeller, suction cover and mouth rings designed for superior wear resistance in abrasive applications, delivering extended service life
- Tsurumi’s exclusive oil lifter device, and dual silicon carbide mechanical seals
- Anti-wicking cable entry system prevents water ingress, protecting internal components
- Side discharge, spiral casing with water jacket improves flow of solids and circulates liquid for motor cooling, enabling extended low-water-level operation
Typical Applications
- Tunnelling and underground works
- Construction projects
- Civil infrastructure projects (road, rail, dam, and bridge)
- Quarry and open-cut mining (pit dewatering and stormwater control)
- Emergency flood and stormwater
- Underground mining operations (shaft and tunnel drainage, sump pumping, and general site dewatering)
