M4 PV 21•28•37 Pump

Variable Displacement Closed Circuit Axial Piston Pumps, Displacement 21 to 37 cm³ (1,28 to 2,26 in³), (Swashplate 18°), Continuous 250 bar (3625 psi), Pressure Intermittent 300 bar (4350 psi), (Power-Transmission Hydrostatic Transmission).

The axial piston pumps series M4 PV is designed to operate in a closed circuit.

Control systems actually available are making easy to use these pumps in any application for the industrial and mobile field.

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 continuous pressure until 250 bar and working peak pressure until 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.
