How does a Magnetic Drive Pump Work?

Magnetic drive pumps have been available for many years and are ideal for use with clean liquids, their obvious advantage in chemical applications is that they eliminate the need for potentially expensive mechanical seals. Magnetic drive refers to the coupling between the motor and the impeller. In traditionally sealed centrifugal pumps the impeller is driven by a shaft directly coupled to the motor and the area where the shaft passes into the pump housing contains a mechanical seal to contain the liquid within the pump. Whereas magnetic drive pumps have a series of magnets driven by the motor that in turn drives magnets encased within the impeller. A shroud encases the impeller and contains a shaft and bearings enabling the impeller to run on a true axis. This means there is no need to have a sealed enclosure and magnetic drive pumps are naturally leakproof.
