Sauer Danfoss MF21 Hydraulic Motor for Concrete Mixer

Sauer Series 20 Piston Motor 
Application Range：
Concrete mixers, mining machinery, vehicles, industrial, road rollers, pavers, stabilized soil mixing machine, concrete pump, pharmaceutical machinery, etc.
Sauer Series 20 Piston Variable Displacement Motor Features:
1. axial piston motor which with fixed displacement swash plate structure,is applicable to closed hydrostatic transmission
2. Output shaft speed is proportional to the input flow of the hydraulic
3. Output torque is proportional to the differential pressure in the hydraulic circuit
4. Motor output shaft rotation direction depends on the direction of flow of the hydraulic fluid
