Description :
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
