Working principle of Magnetic Drive Centrifugal Pump

A Magnetic Drive Centrifugal Pump uses product-lubricated bearings within a pressure boundary and a magnetic coupling to transmit torque over a containment shell to provide total containment of process liquid. The suction and discharge flanges, as well as the casing volute, which houses the impeller, make up the Magnetic Drive Centrifugal Pump casing. The impeller rotates, transferring energy to the liquid and causing the pump to work. The internal pump shaft and shaft sleeves support the impeller. The bush holder, which consists of a stiff holder and bushes or bearings that run against the shaft sleeves, supports the shaft.
The inner magnetic ring completes the inner rotor assembly. This is a ring of outward facing permanent magnets that are co-axially organised and enclosed in a resistant metallic covering. The containment shell is the last component of the liquid contact assembly. With a gasket against the casing, this component is statically sealed. Typically, the containment shell is made of a high-strength, non-magnetic, corrosion-resistant alloy. A second, outer magnetic ring surrounds the first pressure barrier, with magnets facing inwards. The connection housing, which is attached to the exterior bearing assembly, houses the outer magnetic ring.
The liquid is contained when the pump is filled, or ‘primed,’ without the need for any dynamic seals. The operating idea is fairly straightforward. Because the magnets in the outer and inner magnet rings are attracted to each other, the outer and inner rings revolve at the same speed as the electric motor, turning the impeller and allowing liquid to be pumped.
