The GPN-series offers motor outputs of 5.5 to 22 kW. The impeller, agitator and suction plate are made of high-chromium cast iron to ensure longer use against wear. And, if the impeller and suction plate wear down to the point of diminishing pump performance, the plate can be replaced or its gap from the impeller adjusted, giving users an easy and inexpensive means for ensuring extended use.
The GSD is a new series of heavy-duty, high-powered agitator pumps. Driven by 37 to 75 kW motors, they feature the highest head and volume of Tsurumi’s slurry pumps. The impeller, agitator and mouth ring are made of high-chromium cast iron to ensure longer use against wear. Moreover, performance drops due to wear have been minimized by pairing a closed impeller configuration with Tsurumi’s unique mechanism that continuously adjusts the clearance between the mouth ring and impeller. Furthermore, pumps are equipped with seal pressure relief ports that release pump pressure applied to the mechanical seal, thus enhancing reliability in extended use.
