Sauer-Danfoss MF Series — hydraulic motors
Sauer-Danfoss MF Series is a line of fixed-displacement axial piston hydraulic motors for closed-circuit hydraulic systems. The series spans a wide range of frame sizes: MF16A and MF18 belong to the Series 20 family and are used in heavier drives requiring significantly higher output torque. All motors in the series are designed for straightforward servicing — complete disassembly and reassembly can be carried out with standard hand tools.
MF Series models
The series includes motors:
All series are available in the Sauer-Danfoss hydraulics section.
Advantages of the MF Series
- Fixed displacement provides a straightforward and predictable relationship between flow rate and output speed, simplifying hydraulic system setup and calibration
- Parts unification of MF16A / MF18 with Series 20 pumps, reduces spare parts inventory and speeds up field repairs
- High resistance to peak pressures and wear-resistant sliding components ensure reliable operation under continuous reversing loads
- Mounting faces for brakes and gearboxes directly on the motor flange simplify drive unit packaging across a wide range of machine configurations
Applications MF Series
Sauer-Danfoss MF Series hydraulic motors are used in transit mixer drum drives (MF16A, MF18 — Schwing, Liebherr, Putzmeister, Zoomlion), traction and working attachment drives of compact loaders and mini excavators, and in conveyor systems and specialised industrial machinery.
