HP M4 MV 34•46•50•58•65 Motor

Variable Displacement Open or Closed Circuit Axial Piston Motors, Displacement 34 to 65 cm³ (2,08 to 3,97 in³), (Swashplate 18 | 19 | 18 | 18 | 18°), Continuous 250 bar (3625 psi), Pressure Intermittent 330 | 300 bar (4785 | 4350 psi), (Power-Transmission Hydrostatic Transmission).

The HP M4 MV series axial piston motors have been designed to work both in an open and in a closed circuit.

Control systems actually available are making easy to use these motors 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, giving extreme reliability for working continuous pressure unit 250 bar and until 400 bar for peak pressure.

Motors can be supplied on requests with complete accessories such as cross relief and anti-cavitation valves and flushing valve.

Closed circuit axial piston motors are used as hydrostatic transmission components, in conjunction with closed circuit pumps, and found consequently in the widest imaginable range of mobile equipment.

Variable displacement motors are available with two position hydraulic controls, two positions electric control and proportional electric control. Controls can also be customized where particular strategies are required. Possible configurations include circuits with built-in exchange valves and pressure relief valves. Built-in cartridge versions also available for planetary hubs.
