Introduction of Group2 Gear Motors
Group2 Gear motors from GRH can be divided into two types: one is a Gear Pump based on a gear pump; the other is a specially designed Gear Motor. The structure of the gear motor and the gear pump are basically the same, but since the gear motor needs to be loaded and started, and it is required to be able to rotate in the positive and negative directions, the gear motor is different in actual structure from the gear pump.
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.
