Product Description
GPY Series High-Performance Hydraulic Gear Pumps for Forklifts
Product Overview: The GPY Series serves as the vital power core for global forklift lifting systems and material handling machinery. This featured selection covers the entire durable range: GPY-3, GPY-4, GPY-5.8, GPY-7, GPY-8, GPY-9, GPY-10, GPY-11.5, and GPY-12. Engineered with high-strength extruded aluminum bodies and advanced axial pressure compensation, these pumps are specifically designed to meet the rigorous demands of forklifts for high pressure (Rated 25 MPa) and extended service life during frequent lifting and tilting cycles.
Key Technical Advantages:
100% Direct OEM Replacement: Strictly adheres to international forklift OEM specifications. Standardized mounting flanges, shaft ends (splined/keyed), and port positions ensure a seamless installation with major brands like Heli, Hangcha, Lonking, and Tailift.
Superior Pressure Resilience: Rated for a continuous operating pressure of 25 MPa (250 Bar) with peaks reaching 31 MPa (310 Bar). Excellent fatigue resistance allows it to absorb instantaneous load shocks during heavy-duty operations.
High Volumetric Efficiency: Featuring automatic axial gap compensation to minimize internal leakage, maintaining efficiencies over 93% throughout the pump’s service life while effectively reducing system heat generation.
Lightweight & Efficient Heat Dissipation: The optimized aluminum alloy construction reduces overall weight and provides superior thermal management, ideal for continuous high-intensity work within tight engine compartments.
Smooth & Quiet Operation: Precision-ground gear sets drastically reduce flow ripples and mechanical noise, protecting downstream control valves and enhancing operator comfort.
Detailed Models & Parameters:
Core Series: GPY, HGP High Pressure Performance Series.
Model Keywords: GPY-3, GPY-4, GPY-5.8, GPY-7, GPY-8, GPY-9, GPY-10, GPY-11.5, GPY-12.
Displacements: Covering precise flow specs from 3cc to 12cc/rev.
Pressure Ratings: Rated at 25 MPa (250 Bar); Peak pressure up to 31 MPa (310 Bar).
Rotation: Available in Right-hand (R) and Left-hand (L) configurations.
Target Applications: Main lift/steering pumps for 1-3.5 ton forklifts, aerial work platforms, and compact hydraulic balers.
