Product Description
GPY & GPYZ Series High-Performance Hydraulic Gear Pumps
Product Overview: The GPY and GPYZ Series serve as the vital power core for global material handling and mobile hydraulic systems. This featured selection covers precision models optimized for complex duty cycles: GPY-3R715, GPY-4R, GPY-8R839, GPY-11.5R732, and the high-performance specification GPYZ5.8R323B. Engineered with high-strength extruded aluminum bodies and advanced axial pressure compensation, these pumps are specifically designed to meet the rigorous demands of forklifts and compact machinery for high pressure (up to 25 MPa) and long-term operational stability.
Key Technical Advantages:
100% Plug-and-Play Replacement: Strictly adheres to international forklift OEM specifications. Suffix codes like R732, R323B, and R839 guarantee that mounting flanges (pilot diameter), drive shafts (splined/keyed), and port positions are 100% identical for a seamless installation.
Superior Pressure Resilience: Rated for a continuous operating pressure of 25 MPa (250 Bar) with peaks reaching 31 MPa (310 Bar), built to handle the intense load shocks typical of forklift lifting and tilting cycles.
High Volumetric Efficiency: Featuring automatic axial gap-compensated wear plates to minimize internal leakage, maintaining efficiencies over 93% throughout the pump’s service life and effectively reducing system heat generation.
Lightweight & Efficient Heat Dissipation: The optimized aluminum alloy construction reduces overall weight while ensuring efficient thermal management within tight engine compartments, extending seal life.
Quiet Operation: Precision-ground gear sets drastically reduce fluid ripples under high-pressure cycles, protecting downstream control valves and enhancing operator comfort.
