Product Description

Introduction of Group1 Gear Motors

Due to the poor sealing performance and low volumetric efficiency of the Gear Motor, the input oil pressure cannot be too high, the torque is generally not large, and its speed and torque are pulsating with the meshing condition of the gear. Therefore, gear Hydraulic Motors are generally used in the case of high speed and low torque.Group1 Gear motors from GRH have a floating bushing feature with automatic axial clearance compensation.Our cold extrusion motor bodies can endure pressures above 30Mpa. High strength cast iron front & rear covers also enhance our reliability.

They can be divided into two types. One is the single direction gear motor, the other is the bi-direction gear motors. Normally the design of the single direction gear motor is similar to that of the single direction Gear Pump with some slight design differences. Therefore, all GRH pumps have a corresponding single direction gear motor. When placing your order, please refer to the ordering code.

We now focus on the bi-direction gear motors. This motor has a different sealing structure to the single direction motor. The symmetrical sealing (refer to the bottom drawings) separate high pressure from low pressure thus allowing bi-direction operation. The oil from internal leakage returns to tank through the drain port. Normal case drain pressure is limited to 2 bar, but 5 bar is allowed for intermittent operation. High quality of the bushings, bearings and seals adds to the outstanding performance of GRH bi-direction gear motors.



Direction of rotation: bi-direction and single- direction

Permissible ambient temperature range: min= -20℃-max= +60℃

Operating pressures:input side P1 max = refer above data; outlet side P2 max =3 bar

Drain pressure: max = 2 bar, short time: max = 5bar

Fluid temperature range: max=90℃ for NBR rotary shaft lip-type seal, 100℃ for FKM rotary shaft lip-type seal

Viscosity range: min= 10 mm²/s-max= 600mm²/s



Recommended Vicosity range: V=30...45mm²/s

Recommended hydraulic fluids use: GB11118-94 : L-HM46 or equate NFE-603/DIN515524II-85
