Mag-drive pumps or magnetic drive pumps are practically
centrifugal pumps driven by a motor through magnetic coupling instead of a mechanical shaft. The pump works via a drive magnet that eliminates any shaft sealing required by the pump. Then the pumping action is the same as the conventional centrifugal pump, where fluid is moved from suction to discharge through centrifugal force.
Mag-drive pumps are sealless pumps, which is a great advantage as this design eliminates the risks of leaks. This makes mag-drive pumps perfect for pumping hazardous fluids that should not leak into the environment and ultra-pure liquids and hard-to-seal products.
