Circular magnetic pump, also known as magnetic circulating pump, is widely used in national defense, petroleum, chemical, pharmaceutical and other fields. Its main purpose is to pump flammable, explosive and toxic substances in these fields.

The structure of the circulating magnetic pump is the same as that of the shield pump in the same type of pump without shaft seal. The structure of the magnetic pump is static seal but no seal, so it can ensure no drop when liquid is transported. Circulating magnetic pump by the pump, magnetic actuator, the motor consists of three parts. The key components of the magnetic actuator consists of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation cover. When the motor drives the outer magnet rotor to rotate, the magnetic field can penetrate the air gap and the non-magnetic substance to drive the inner magnet rotor connected with the impeller to rotate synchronously to realize the powerless contact transmission and transform the dynamic seal into the static seal. As the pump shaft, the inner rotor is completely closed by the pump body and the isolation sleeve, thus completely solving the problems of running, running, dripping and leakage, and eliminating the leakage of flammable, explosive, toxic and harmful media through the pump seal in the refining and chemical industry Of the security risks, effectively guarantee the physical and mental health and safety of workers.
