Submersible High Volume Dewatering TSURUMI Slurry Pump GSD Series


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.
