Magnetic pump is a centrifugal pump that indirectly rotates by magnetic attraction. The difference between it and ordinary centrifugal pumps is that it eliminates the shaft seal and is mainly composed of pump casing, impeller, inner magnetic rotor, reinforcement sleeve, outer magnetic rotor, motor, base, and other parts. The core component of a magnetic pump is a magnetic coupling, which mainly consists of an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation sleeve. The working principle of a magnetic pump is that when the motor drives the outer magnetic rotor to rotate, the magnetic field penetrates the isolation sleeve and drives synchronous rotation with the inner magnetic rotor, thereby driving the impeller to rotate and achieve non-contact synchronous torque transmission, achieving true zero leakage.
