Data Sheet

Reverse Displacement Motor (RDM)
Open Circuit Piston Motor
For more than 40 years, Danfoss has been developing
state-of-the-art components and systems for mobile
machinery used in off -highway operations around the world.
We have become a preferred supplier by offering the best of
what really matters: the hardware inside your vehicle
application.
The Reverse Displacement Motor (RDM) is designed for use in
mobile open circuit applications. It offers reverse functionality
without external valves, and provides system robustness with
available anti-cavitation and shock valves. The RDM uses the
existing and proven technology of the Danfoss L/K motor.
These motors have been optimized with regard to options, life,
package size and installed cost.
The RDM is a two-position reversing motor, with smooth,
shift-on-the-go capability. The integrated proportional shifting
valve uses system pressure.
It allows reversing functionality without external valves and
external pressure supply.
