Sealless Magnetic Drive Pump

A sealless mag drive pump is a conventional centrifugal pump without the dynamic seal that would normally be used to seal the pump shaft. This dynamic seal is replaced by a static containment shell to form a completely sealed liquid end or pressure boundary.The principle of operation is very simple. The magnets in the outer and inner magnet rings are attracted to each other, so as the electric motor rotates, the outer ring and the inner ring rotate at the same speed, thus rotating the impeller and causing liquid to be pumped.
