| Overview of HENGYUHANG Group 1PDF External Gear Pumps
The HENGYUHANG Group 1PDF series represents advanced external gear pump engineering, delivering high pressure capability, superior volumetric efficiency, and exceptional durability across an extended displacement spectrum from 1.4 up to 13.8 cm³/rev. Designed specifically for universal replacement and custom OEM hydraulic installations, the 1PDF series bridges compact Group 1 mounting envelopes with displacement outputs typically found in larger frame sizes, enabling substantial power density improvements in space-constrained applications.
Built with an extruded high-strength aircraft-grade aluminum alloy body paired with high-tensile spheroidal graphite ductile cast-iron or aluminum front mounting flanges and rear covers, the pump exhibits outstanding resistance to cyclic pressure fatigue and structural housing deformation. The internal rotating group consists of case-hardened alloy steel precision gears, hobbed and shaved to tight surface tolerances (Ra < 0.2 μm) to minimize mechanical friction and fluid turbulence. The drive and driven gear journals rotate inside heavy-duty PTFE-lined DU composite hydrodynamic bushings lubricated continuously by internal fluid bypass channels. Hydrostatic axial pressure balance thrust plates automatically adjust against the gear side faces under shifting system pressures, eliminating volumetric slippage, holding overall efficiency above 93%, and ensuring whisper-quiet operation across the entire rotational speed spectrum.
