Italgroup R8D Series Motors – Replacing IAMD Motors


Italgroup R8D is a heavy duty,  single displacement hydraulic motor.

The R8D motor is the evolution of the former Italgroup IAMD series, built on 20 years of improvements. With unchanged dimensions and mounting face the new R8D series is fully interchangeable with the old IAMD series.

The use of low friction materials and hydrostatic balancing make the R8D ideal for the most demanding applications – where high performances are required even for long duty periods including: marine and offshore equipment, winches, conveyors, plastic injection moulding machines, steel bending machines, fork lift trucks, skid-steer loaders, dumpers, agricultural and forestry machinery, municipal vehicles and airport equipment.

The R8D range is available in displacements ranging from 0cm³ to 5400cm³ (cc/rev) – click on the ‘Model Codes and Technical Data’ tab for full details.

Other features include:

  • wide speed range from 0.5 to 950 rpm
  • very high volumetric efficiency and mechanical efficiencies
  • smooth performance even at low speeds
  • high starting torque / constant torque
  • freewheeling option
  • interchangeable mounting face with main competitors
  • compact design
  • bi-directional
  • optional speed sensor and built-in valves
  • high radial and axial force allowed
  • low maintenance and high reliability
