MFH series hydraulic motors are a cost competitive solution for a variety of application conditions.The design is based on the Sauer 20 series. The large-scale modernization, carried out on the basis of long-term experience of the company, allowed to increase considerably technical and operational characteristics of units and kept the famous reliability and durability. These motors meet the requirements of heavy-duty applications in construction, road and agricultural machinery. They are used as a part of hydrostatic transmission of travel drive or operating equipment of harvesters, road and construction mobile machines. The compact version of the motor with integrated valves expands application segments of these units further.

Features:
- Swashplate design.
- High hydromechanical efficiency.
- Bimetal bearing plate has a high wear resistance.
- Lightweight piston provides reliability in operation at high speeds.
- Mounting flanges according to SAE.
- Tapered roller bearings enable the hydraulic motor to withstand high radial and axial loads.
- Shaft seals (face seal or lip seal) provide reliable external tightness.
- Built-in hydraulic equipment optionally.

Application:
- Harvesters
- Concrete mixer trucks
- Asphalt pavers
- Oil-and-gas machines
- Mining machines
