Feature:
1. Energy Saving: no need for independent lubrication and cooling water, reducing energy consumption. By coupling drive into synchronous drag, there is no contact and friction, small power consumption, high efficiency, and damping and vibration damping, reducing the impact of motor vibration on the pump and the impact on the motor when the pump undergoes cavitation vibration.
2. Overload Protection: when overloaded, the inner and outer magnetic rotor slips relatively, which has a protective effect on the motor and pump.
3. No Leakage: the pump shaft is turned into a closed static seal from the dynamic seal, completely avoiding the leakage of the medium, which can effectively prevent the flammable, explosive, toxic and harmful medium in the oil refining and chemical industry from leaking through the pump seal, and protect the safe production and the physical and mental health of the workers.
