Specification :

The crankshaft design radial piston hydraulic motor, by using static equilibrium structure on the hydraulic motor, reduce friction loss in the process of force, this unit has high mechanical efficiency ( > 93% ) , With oil technology is simple and reliable, sealed performance is good, so it has the high volume efficiency ( > 99) . Due to the improvement of the organization to minimize friction losses and adopts the imported seal, and low efficiency, stable performance in Grimm/ MIN mining can be stable operation, the speed under large scope ( 1-1000R/ MIN) 
Main characteristics:
High mechanical efficiency
High volume efficiency
Hhigh torque
low speed
