Magnetic pump is composed by three parts of the pump, magnetic drive, electric motors. The key components of the magnetic actuator by the external magnetic rotor within a magnetic rotor and non-magnetic isolation composition. When the motor drives the outer magnetic rotor rotation, the magnetic field can penetrate the air gap and non-magnetic material, driven impeller connected to the inner magnet rotor for synchronous rotation of power non-contact transmission, the dynamic seal conversion for static sealing. Magnetic shaft inside the magnetic rotor pump body, isolated sets of completely closed, completely solved the problem of "Run, run, drip, leak," to eliminate the refining and chemical industry, flammable, explosive, toxic, harmful media by magnetic pump seal leakage security risks, to ensure the physical and mental health of workers and production safety.
