Hydraulic piston motors MSI are designed to perform the most demanding operating conditions. Their construction allows for optimum integration into receiving unit, and in particular a planetary gearbox. This combination enables to obtain similar torque as in case of low speed motors. The MSI motors can achieve power over 10 kW per kilo.

Rotational speed range: from 50 through 6900 rpm; maximum continuous pressure: up to 400 bar.

Whole range of MSI series hydraulic motors by Hydro Leduc is based on bent axis technology with direct drive and conical pistons. The MSI motors suitable for use in open or closed loop. The incresed bearing capacity and components made from high quality materials provide extremely durability of these motors. Additionally, reinforcedshaft sealcausesthe MSI motors are resistant toback pressureon motor drain return lines up to 5 bar.

The MSI motors are interchangeable with models of: A2FE32/61W-VAL010, A2FE32/61W-NAL010 and F12-030-MF-CF-C.


  • Displacement: 32 – 108 cm3/rev;
  • Rotational speed range: 50 (in certain conditions) – 6900 rpm;
  • Maximum pressure: 400/450 bar (continuous/peak);
  • Maximum power: 132 – 290 kW.


  • Global efficiency over 90%;
  • Hihg powe per kilo – over 10 kW/kg;
  • High durability;
  • Lower noise level due to direct drive;
  • Rotating smoothness and constant torque;
  • High pressure oil injection on piston heads reduces friction, heat and wear.


The MSI motors are used in heavy duty winchers insensitive to wetting, in high power crushers, in forestry machines, driving vehicles and other applications.
