Nominal pressure 210 bars, Maximum pressure 350 bars.
 
The Sauer MF axial piston variable displacement motors, Series 20, are of swash plate construction with variable flow capability suitable for hydrostatic transmissions with closed circuit. The flow rate is proportional to the motors driven speed displacement, which, in turn, is determined by the swash plate angle. The latter is infinitely adjustable between zero and maximum displacement. Flow direction is reserved by titling the swash plate to the opposite side of the neutral or zero displacement position. These units and parts are fit, form and function replacements for Sauer-Sundstrand series 20 components.
 
- Suitable for a variety of applications
- Multiple displacements and options available
- 8 different frame sizes
- Engineered to provide a long service life and reliability
- Fixed displacement motor can be operated in either direction of rotation
- Multiple drive shaft options and control options
- Heavy duty bearings and shafts
- Easily serviceable
- Replacement parts also available
- Direct replacements for Sauer-Sundstrand
Features 
The full-length shaft with a high efficient tapered roller bearing arrangement offers a high loading capacity for external radial forces. Additional motors can be built on. The hydro-mechanical servo displacement control maintains the selected swash plate position and hence motor displacement.
Upon release of the control handle, the swash plate automatically returns to the null position and the flow become zero.
High case pressures can be archived without leakage even at the lowest temperature by using suitable shaft seals. The servo valve arrangement offers the facility to incorporate function regulators and remote control system. Axial piston units are designed for easy servicing, complete dismantling and reassembly can be carried out standard hand tools, and all components or sub-assemblies are replaceable.
Servo Displacement Control (Linear response)
Regular by control handle on the servo valve, the swash plate can be infinitely varied in both direction with the help of the servo system.
The motor displacement resulting from any control handle position can be established using figures (5a - 5c).
The angle of the control handle for stroke initiation and for the final position of the stroke can vary from unit to unit within the range of the tolerance band.
