Product Description
GPY Series High-Performance Micro Power Unit Gear Oil Pumps
Product Overview: The GPY Series is a high-pressure power core specifically engineered for compact hydraulic systems. As a premier external gear pump, this series is the industry standard for AC/DC micro-hydraulic power units due to its exceptional power density and pressure-balancing capabilities. This featured range includes core models: the top-selling GPY-4R, GPY-F8R, and the high-displacement GPY-11.5R. Featuring reinforced aluminum alloy bodies and specialized surface treatments, these pumps deliver outstanding operational stability even under frequent start-stop cycles and continuous high pressure (Rated 21 MPa).
Key Technical Advantages:
Ultra-Compact Footprint: Optimized for the limited internal space of power packs, with flange and shaft specs designed for direct integration with mainstream motors.
High Pressure Resilience: Rated for a continuous working pressure of 21 MPa (210 Bar) with peak pressures reaching 25 MPa, ideal for heavy-duty lifting and clamping applications.
Axial Gap Compensation: Equipped with floating bushing technology that adjusts clearances based on real-time load. This maintains volumetric efficiency above 93%, effectively minimizing system heat and extending seal life.
High-Speed Capability: Optimized gear set design supports high-speed operation up to 3500-4000 RPM, allowing for smaller pump sizes while maintaining rapid system flow response.
Target Applications: Truck tail lifts, electric forklift steering circuits, hydraulic lifting platforms, micro-sweepers, and various mini-hydraulic power units.
Detailed Models & Parameters:
