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.

Performance features

  • Particularly robust design
  • High efficiency, high continuous output
  • Special version suitable for flame-retardant and biodegradable liquids
  • High thermal shock resistance
  • High absorption of radial and axial loads
  • Narrowly graduated displacement volumes

Applications of radial piston motors RM 250X - RM 5000X

Shredder in recycling technology

In recycling technology, hydraulic motors from Düsterloh Fluidtechnik are used in shredders to drive the rollers. The shredding process is usually at the beginning of the recycling cycle. Our motors are especially robust and insensitive to occurring shocks and vibrations. Speed and torque are easy to regulate and full torque is available even at the lowest speeds. The hydraulic motor can also be combined with a gearbox and brake.
