Product Description
GPY & GPYZ Series High-Performance High-Pressure Gear Pumps
Product Overview: The GPY and GPYZ Series are recognized benchmarks for compact, high-reliability power cores in the hydraulic transmission sector. This featured selection includes core displacement models including GPY-1R, GPY-2R, GPY-3R, GPY-4R, the specialized GPY-8R721, and the specific mounting configuration GPYZ5.8R323B. Specifically engineered for industrial equipment requiring high-pressure output within limited installation spaces, these pumps utilize high-strength extruded aluminum bodies and axial pressure compensation. Featuring advanced side-plate compensation, the GPY series maintains elite volumetric efficiency even at operating pressures of 25 MPa, making it the premier choice for lift platforms, compact forklifts, machine tool hydraulics, and various Hydraulic Power Units (HPU).
Key Technical Advantages:
Elite Pressure Capability: Constructed with reinforced aluminum housings and specialized heat-treated gears, capable of handling rated pressures up to 21-25 MPa with exceptional stability under high-load cycles.
Precision Volumetric Efficiency: Equipped with automatic axial gap compensation side-plates to minimize internal leakage, maintaining efficiencies over 93% at rated speeds to effectively reduce system heat.
Ultra-Compact & Lightweight: An elite power-to-weight ratio makes it the first choice for integration within space-constrained mobile machinery and miniature hydraulic stations.
Quiet & Smooth Output: Precision-ground gear sets combined with optimized relief grooves drastically reduce hydraulic ripples and operational noise, ensuring precision in system movements.
Standardized Mounting Configs: Available with R (Clockwise) rotation and various flange/shaft options (such as the 323B specification) for seamless coupling with standard engine and motor power sources.
Detailed Models & Parameters:
Core Series: GPY & GPYZ High Pressure Series.
Model Keywords: GPY-1R, GPY-2R, GPY-3R, GPY-4R, GPY-8R721, GPYZ5.8R323B.
