Accessories for hydraulic motors

Coaxial or angular gear units must be completely filled with oil when installed vertically.

During filling, an air bubble may form in the upper part at the level of the shaft seal, which must be eliminated to prevent insufficient lubrication. Since the oil volume increases as the temperature rises, an expansion tank with oil level control and breather filter must be installed to compensate and prevent harmful excess pressure inside the gear unit.

Hydraulic motors KM 11 - RM 11

In radial piston engines, seven radially arranged pistons act on the crankshaft via a heptagonal ring with needle cage. In the KM 11 engine type, control is by means of translational movement of the control ring and gap seal to the housing. The RM 11 radial piston engine, on the other hand, has a backlash-adjusting control system. This makes the motor less sensitive to the effects of pressure and temperature and reduces leakage.

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.
