| Overview of HENGYUHANG Group 2PDF External Gear Pumps
The HENGYUHANG Group 2PDF series represents heavy-duty industrial external gear pump engineering, delivering outstanding pressure handling, high volumetric efficiency, and prolonged service longevity across a versatile displacement envelope from 4.0 up to 30.0 cm³/rev. Specifically developed for universal replacement and custom OEM integration, the 2PDF platform conforms to standard Group 2 dimensional envelopes while providing enhanced pressure margins and structural robustness suitable for demanding continuous-duty hydraulic circuits.
Constructed using a high-density extruded aircraft-grade aluminum alloy gear casing paired with high-tensile spheroidal ductile cast-iron or aluminum front mounting flanges and rear end-covers, the pump resists housing barrel dilation and mechanical fatigue under severe cyclic shock pressures. The internal pumping core features hardened and micro-finished alloy steel gear sets supported by high-load hydrodynamic composite DU/PTFE sleeve bushings continuously bathed in hydraulic fluid. Floating hydrostatic thrust balance plates automatically compensate for axial wear and thermal clearance shifts, sustaining volumetric efficiencies above 94% and minimizing operating noise across mobile machinery cab environments and industrial manufacturing facilities.
