Radial piston motors

RM 250X – RM 5000X

Our radial piston motors of the "RMX" series are especially suitable for applications where particularly high continuous power is required or the ambient conditions are very harsh.

They are designed in piston connecting rod construction and with roller bearings for very long service life.

This is why, among other things, they have a high thermal shock resistance and can absorb high radial and axial loads. Furthermore, the design guarantees very high efficiencies. Another special feature is the possibility to operate the motors in special design also with flame retardant and biodegradable fluids.

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.
