GPC4 Series Gear Pump | GPC4-20, GPC4-32, GPC4-63 | GPC4-32-B6F1-30-R/L High Pressure Pump

GPC4 Series Heavy-Duty High-Pressure Hydraulic Gear Pumps

Product Overview: The GPC4 Series represents a premium line of high-pressure cast iron gear pumps engineered specifically for extreme operating environments. This featured selection covers core displacements including GPC4-20, GPC4-32, and the high-flow GPC4-63 models. As the definitive power source for excavators, bulldozers, and heavy-duty mobile machinery, the GPC4 series utilizes rugged cast iron bodies and advanced axial pressure-compensated side plates. It delivers elite volumetric efficiency even at operating pressures of 25 MPa. We provide full specifications including GPC4-32-B6F1-30-R (Clockwise) and GPC4-32-B6F1-30-L (Counter-clockwise) for perfect OEM alignment.

Key Technical Advantages:

• Heavy-Duty Cast Iron Build: Constructed with high-strength cast iron housings for superior thermal stability and impact resistance, built to withstand frequent instantaneous pressure spikes.

• Superior Volumetric Efficiency: Equipped with automatic axial gap compensation to minimize internal leakage, maintaining efficiencies over 92% at rated speeds to reduce system heat loss.

• Standardized B6F1 Interface: Features international B6F1-30 mounting specifications, ensuring seamless “Plug-and-Play” replacement and rapid installation for major construction machinery brands.

• Dual-Rotation Options: Available in R (Clockwise/CW) and L (Counter-clockwise/CCW) configurations to flexibly match the output rotation of various engines or motors.

• Quiet & Smooth Performance: Precision-machined high-hardness gear sets significantly reduce pressure ripples and mechanical noise, enhancing the overall smoothness of the hydraulic system.
