Radial piston motors

RM 80N – RM 250N

Our RMN series motors have a backlash-adjusting control system and pistons that transmit energy to the shaft via polygon rings with bearings.

They can be operated at higher powers than our KM motors.

In addition, the larger swallow volumes allow for higher torque.

Nevertheless, the motors still have a compact design and can therefore also be used in confined installation spaces.

Application areas of valve assemblies

Wagon puller in mining

Our hydraulic motors are used in mining. Underground, rail-bound trolleys are pushed or pulled into or out of freight elevators by hydraulically driven trolley pullers.

With hydraulic motors of the RMX series, Düsterloh Fluidtechnik manufactures particularly robust motors that ensure reliable movement of the trolleys. Precise control of the motors is guaranteed by mounting the valve assemblies directly on our motors.
