  • GHM Series

    GHM series Hydraulic motor are our latest products, which accept higher speed and higher presssure. The acting module of motor is designed with inside flushing valve block, required higher quality castings; special material for the key friction pairs; advanced heat treatment. Highly impove the motor's overall perfomance and cost effectiveness.  

Product features

1. The oil distribution system of the motor and the internal motor power module are made of high wear-resistant material, which reduces the friction loss and improves the running speed and service life of the motor.

2. Adopt high strength bearings to improve the bearing capacity of the motor.

3. For each group of friction pairs, the machining accuracy is improved to reduce the friction loss under high speed operation;

4. For the GHM hydraulic motor, the oil tray with internal flushing device is equipped, which increases the oil flow channel, can cool and lubricate the parts in the motor under the condition of large flow, and reduce wear; It can cool the bearings of the motor and extend its service life.

5. The motor is equipped with flushing device. When the user chooses the configuration, the oil pan should be 72 degrees. And need to determine the motor inlet direction.



  • Range of application

    Can be widely used in hydraulic system of construction machinery, shipbuilding machinery, agricultural machinery, transportation, oil mining, machinery manufacturing and other industries.

Product identification description

Computational formula

①    The actual output torque of the hydraulic motor:M=0.159(P1-P2)V·ηm(N.m)

Where:P1、P2------------------------- Inlet and outlet pressure(MPa)

V--------------------------------- Displacement(ml/r)

ηm------------------------------- Mechanical efficiency(%)

②    Output power of the hydraulic motor:

N=(M·n)/9950(kW)N=[q(P1-P2)/60000]·ηm·ηv(kW)

Where:n-------------------------------- Rotation speed(r/min)

q-------------------------------- Input flow(ml/min)

ηv-------------------------------- Volumetric efficiency(%)

③    Rotating speed of the hydraulic motor:

n=q/V·ηv(r/min)
