According to the principle that the magnetic field can penetrate the air gap and non-magnetic medium, when the motor drives the outer magnetic rotor to rotate, the inner magnetic rotor connected to the impeller is coupled to rotate synchronously through the action of the magnetic force line, realizing the non-contact transmission of torque, by In the conventional pump, one shaft with a shaft seal part is changed to two shafts with a spacer sleeve structure, and the dynamic seal is converted into a static seal. The pump shaft and the inner magnetic rotor are completely sealed by the pump body and the spacer sleeve, thus completely solving the problem. The leakage problem of the medium has also completely solved the problem of "running, popping, dripping, and leaking", and eliminated the safety hazards of flammable, explosive, toxic, and harmful media in the refining and chemical industry leaking through the pump seal, effectively ensuring the physical and mental health of employees. Healthy and safe production.
