Product Description
Sauer-Danfoss MF Series Fixed Displacement Axial Piston Motors
Product Overview: The Sauer-Danfoss MF Series (part of the renowned Series 20 family) is one of the most reliable axial piston motors in the hydraulic industry. Known for its simple slipper-type construction and high mechanical efficiency, these motors are widely used in closed-circuit hydrostatic transmissions. This selection features the full range of core specifications: from the compact MF20 and MF21 to the mid-sized MF22 and MF23, and the heavy-duty MF24, MF25, and MF26, including specific models like MF22-031-50. MF motors are the premier choice for concrete mixers, harvesters, and road construction machinery due to their extreme durability and ease of maintenance.
Key Technical Advantages:
Proven Series 20 Design: Utilizing decades of globally verified axial piston technology, the robust structure is built for continuous operation in the harshest environments.
High Pressure Capability: Capable of handling rated pressures up to 420 Bar (6000 PSI), delivering powerful output torque for heavy-load startups.
Exceptional Compatibility: As an industry standard, the MF series pairs perfectly with most closed-circuit pumps (such as the PV20/22 series) for precise speed control and power transmission.
Low Maintenance Cost: Modular component design makes seal replacement and major overhauls exceptionally straightforward, significantly reducing costly equipment downtime.
Target Applications: Concrete mixer drum drives, paver travel systems, combine harvester drives, and various heavy-duty industrial hydrostatic transmissions.
