High Pressure Hydraulic Gear Pump | GPP1-AOC80AER, GPP0-AOD40A40AL | GSP2, GXP10 Series

GPP / GSP / GXP Series High-Pressure Industrial Hydraulic Gear Pumps

Product Overview: The GPP, GSP, and GXP Series are premium gear pumps engineered to meet the demanding requirements for high power density and extreme operational reliability in construction and industrial hydraulics. This selection features flagship precision models: the high-pressure pilot pump GPP1-AOC80AER-113, micro-specification GPPO-AOD40A40AL-111, and the reinforced GSP2, GSP2H, GXP05, GXP0, and GXP10 platforms. Constructed with high-strength extruded aluminum bodies and axial pressure compensation technology, these pumps maintain elite volumetric efficiency at operating pressures up to 25 MPa. They serve as the ideal power core for excavator pilot circuits, steering systems, and various compact Hydraulic Power Units (HPU).

Key Technical Advantages:

• Extreme Pressure Resilience: Rated for a continuous operating pressure of 21 MPa (3000 PSI) with peaks reaching 25 MPa, reinforced to handle instantaneous pressure spikes in complex duty cycles.

• Precision Pilot Control: Optimized gear meshing profiles deliver extremely smooth and pulsation-free flow, ensuring maximum sensitivity and accuracy for excavator joystick operations.

• High-Efficiency Engineering: Equipped with automatic axial gap compensation side plates to minimize internal leakage, maintaining efficiencies over 93% throughout the pump’s service life and reducing heat buildup.

• Compact & Modular Design: From the micro-sized GXP05 to the mid-sized GSP2H, these platforms offer a fine-tuned displacement gradient, ideal for confined spaces behind main pumps or within machine tool enclosures.

• 100% Fitment Accuracy: Strictly adheres to standard interface codes like 113 and 111, ensuring identical pilot diameters, shaft ends, and port positions for guaranteed “Plug-and-Play” replacement with original OEM equipment.
