High-Output Triplex Plunger Pump for Demanding Industrial Systems

The Giant GP7655 hydraulic drive pump (80 GPM @ 2500 PSI) is engineered for high-volume, high-pressure industrial applications requiring durability, efficiency, and continuous-duty reliability. Designed with a hydraulic integral mount drive system, this triplex plunger pump delivers powerful flow capacity while maintaining stable pressure output in severe operating environments.

Featuring a nickel-plated spheroidal cast iron manifold and solid ceramic plungers, the GP7655 provides superior wear resistance, corrosion protection, and extended service intervals. The integrated oil cooler assembly enhances thermal control, protecting bearings, seals, and crankshaft components during sustained operation.

This configuration is ideal for operators requiring increased cutting and flushing power compared to lower-PSI variants.
