HM PX Pump

Variable Displacement Closed Circuit Axial Piston Pumps, Displacement 9+9 to 16+16 cm³ (0,55+0,55 to 0,97+0,97 in³), Continuous 280 bar (4060 psi), Pressure Intermittent 300 bar (4350psi), (Power-Transmission Hydrostatic Transmission).

The axial piston pumps series HM PX is designed to operate in a closed circuit.

The available control systems make it easy to use these pumps in any application for industrial and mobile fields.

Development of rotating groups, especially designed, united to an accurate study of oil passage sections, allow high-speed rotation, like required by modern diesel engines, giving extreme reliability for working peak pressure up to 350 bar.

It is possible to couple tandem versions, by means of coupling flanges optionally available.

Closed circuit axial piston pumps are used as hydrostatic transmission components in self-propelled machines and for rotary drives in both fixed and mobile equipment of all kinds.
