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.

Subplates for valve assembly DN6/DN10 according to DIN24340 (ISO 4401 - CETOP - RP121H) and DN8 according to ISO 10372-4.Combinations with integrated brake control are available.

Valve assembly with pressure relief and feed > 1.5 bar by 2 pressure feed valves MHDB16K2-2x420VFB (pmax. = 420 bar, Qmax. = 100 l/min). The integrated feed check valves open from 1.5 bar. In order to prevent a feed-out, the feed pressure at port "E" must be higher, or an additional protection by an external check valve at port "E" is recommended. Combinations with variant 1 available.

Valve assembly with pressure relief and supply >0.1 bar by 2 direct operated pressure valves DBDS10K1x/315bar (pmax. = 315 bar, Qmax. = 80l/min). The separate feed check valves open at >0.1 bar. Combinations with variant 1 are also available.

Valve assembly with pressure relief and supply > 0.1 bar through a pilot operated double pressure valve DDP16ENxxx (pmax. = 480 bar, Qmax. = 400 l/min) or DDP32ENxxx (pmax. = 480 bar, Qmax. = 700 l/min). The valve pressure setting applies to both directions of rotation. The valve with leakage line "L3" always works against the leakage pressure. Combinations with variant 1 are available, on request also with valve bodies > DN10.

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.
