Product Description

GPYZ Series Ultra-Compact High-Performance Hydraulic Gear Pumps

Product Overview: The GPYZ Series is a precision-engineered power source specifically designed for space-constrained hydraulic systems requiring high-pressure output. Featuring a high-tensile extruded aluminum alloy body and precision-ground steel gears, the GPYZ series offers an exceptional power-to-weight ratio and superior resilience against pressure spikes. This featured range highlights core models: GPYZ3R, GPYZ4R, GPYZ5.8R, GPYZ7R, GPYZ8R, GPYZ9R, and the high-flow GPYZ11.5R. Its advanced axial gap compensation technology ensures maximum volumetric efficiency even under fluctuating load conditions.

Key Technical Advantages:

  • Ultra-Compact & Lightweight: Approximately 20% smaller than standard gear pumps, making it the definitive choice for micro hydraulic power packs and embedded automation systems.

  • Superior Pressure Resilience: Despite its compact footprint, it handles rated pressures up to 21 MPa (3000 PSI) and peak capabilities up to 25 MPa, effortlessly driving heavy-duty lifting mechanisms.

  • High Speed & Low Noise: Optimized gear meshing curves and self-lubricating bearings support operational speeds up to 4000 RPM while maintaining an absolute minimum of mechanical noise.

  • 100% Power Unit Compatibility: The “R” suffix denotes clockwise rotation, with standard mounting interfaces designed for seamless integration with mainstream AC/DC motor groups.

  • Target Applications: Electric forklifts, scissor lifts, tailgate lifters, laboratory hydraulic test benches, and automated clamping systems.

Detailed Models & Parameters:

  • Core Series: GPYZ High-Pressure Mini Gear Pump Series.

  • Model Keywords: GPYZ3R, GPYZ4R, GPYZ5.8R, GPYZ7R, GPYZ8R, GPYZ9R, GPYZ11.5R.

  • Displacements (ml/rev): Featuring precise specifications: 3ml, 4ml, 5.8ml, 7ml, 8ml, 9ml, and 11.5ml.

  • Pressure Ratings: Rated at 21 MPa (210 Bar); peak pressure capability up to 25 MPa (250 Bar).

  • Rotation Spec: R (Clockwise/CW).
