Magnetic pump (also known as magnetic drive pump) is mainly composed of pump head, magnetic drive (magnetic cylinder), motor, base and other parts. The magnetic drive of the magnetic pump is composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate through the coupling, the magnetic field can penetrate the air gap and the non-magnetic material isolation sleeve, and drive the inner magnetic rotor connected to the impeller to rotate synchronously, realizing the non-contact synchronous transmission of power, and will easily leak The dynamic seal structure is transformed into a static seal structure with zero leakage. Since the pump shaft and inner magnetic rotor are completely sealed by the pump body and the isolation sleeve, the problems of "running, popping, dripping, and leaking" are completely solved.
