Magnetic drive gear pump (hereinafter referred to as magnetic pump), usually by the motor, magnetic coupling and gear pump composition of the magnetic pump its motor through the magnetic coupling and the outer magnet together, the impeller and the inner magnet together. Between the steel and the inner magnet with a fully sealed isolation sleeve, the inner and outer magnets completely separated so that the inner magnet in the medium, the motor shaft through the magnet pole between the suction force directly drives the impeller rotation. Its main feature is the use of magnetic coupling transmission of power, no leakage, when the motor drives the magnetic coupling outer magnet rotation, the magnetic field lines through the gap and the isolation sleeve, acting on the magnet, the pump rotor and motor synchronous rotation , No mechanical contact to transmit torque at the pump shaft power input, because the liquid is enclosed in a stationary isolation sleeve, there is no dynamic seal and therefore no leakage at all. Leakless magnetic pump is the ideal green chemical equipment, it will be chemical , Petrochemicals, pharmaceuticals and printing and dyeing and other production enterprises increase production and consumption savings, eliminate pollution, environmental protection, safety and labor protection and other aspects of bringing higher economic and social benefits.
