Hydraulic Gear Motors
Hydraulic gear motors convert hydraulic energy from a hydraulic pump into mechanical energy for rotation, thus, driving the load to work. This gear motor is also used as a hydraulic pump. It features an excellent starting performance, is not sensitive to oil contamination, features a wide speed range, a small inertia, excellent impact resistance, easy to maintain and reliable to operate. Precisely processing each part ensures a higher mechanical efficiency and strict process control guarantees a reliable product quality.

GRH offers 0.5cc-200cc hydraulic gear motors, available in aluminum and cast iron. According to the rotating direction, it can be divided into unidirectional gear motor and bidirectional gear motor, GRH can also customize the motors to meet specific application requirements.
