Rotor

1. After the hollow rotor weight is reduced, the axial torque with the conventional rotor is weakened, the starting torque is reduced, the selection of the gear motor is smaller, the customer's use cost is greatly reduced, and the effect of environmental protection and energy saving is achieved.

2. Because the friction is closely related to the weight, compared with the same solid rotor, after the weight is reduced, the rotor friction is weakened during the operation of the pump, and the service life is increased.

3. The vibration of the pump is significantly reduced during rapid start and high-speed operation.

4. During the operation of the equipment, the noise decibel is greatly reduced, and there will be no noise pollution.
