Product Description
GPY Series High-Performance Micro Hydraulic Gear Pumps
Product Overview: The GPY Series is a micro external gear pump specifically engineered for compact hydraulic systems. Known for its ultra-small footprint, high pressure-bearing capacity, and exceptional operational quietness, this series is the premier choice for mobile hydraulic equipment and small Hydraulic Power Units (HPU). This featured range covers the entire spectrum: from micro specs GPY-3, GPY-4, and GPY-5.8 to medium flow models GPY-7, GPY-8, GPY-9, and GPY-11.5.
Key Technical Advantages:
Compact & Lightweight: Utilizing a high-strength extruded aluminum alloy body, these pumps are incredibly light and space-efficient, ideal for truck tail lifts, aerial work platforms, and medical devices.
High Volumetric Efficiency: Equipped with an automated axial pressure compensation structure, maintaining efficiencies over 93% even under high-pressure conditions of 21 MPa, effectively minimizing internal leakage.
Ultra-Quiet Operation: Precision-ground gear sets combined with optimized intake port designs significantly reduce flow ripples and mechanical noise, delivering smoother hydraulic output.
100% Direct Replacement: Adheres to international mounting standards, including standard oval flanges and various shaft configurations (Keyed or Splined), ensuring seamless compatibility with existing systems.
Target Applications: Forklift lift systems, truck tail lift units, hydraulic scissor lifts, waste compactors, and medical bed actuators.
