HM PF 23•28•32 Pump

Bent-Axis Axial Piston Pumps, Fixed Displacement 23 | 28 | 32 cm³ (1,4 | 1,71 | 1,95 in³), Continuous 350 bar (5075 psi), Pressure Intermittent 400 bar (5800 psi), (Power-Transmission Hydrostatic Transmission).

The HM PF 23 | 28 | 32 fixed displacement axial piston pump is designed to work in an open circuit.

The system is designed in order to obtain 40° angle of inclination of the pumps with respect to the axle of the outgoing shaft.

This geometry allows:

  • High static torque
  • High volumetric and mechanical efficiency
  • High maximum pressure

Bent-Axis fixed displacement axial piston pumps for open circuit applications are designed for operation in systems typified by heavy duty work cycles.
