Lets briefly discussion how mag drive pumps work
All mag drive pumps compose of two components: the outer mag assembly and the impeller
The mag-drive pump eliminates the direct drive mechanism and replaces it with a magnetic field. An outer magnetic bell housing is mounted on the end of the pump shaft. This outer bell is aligned on the outside of the rear casing. The pump impeller is connected to a smaller magnet assembly and rides on an internal shaft and bushing assembly. (The liquid end parts are all isolated within the fluid head of the pump without the need for a mechanical seal.) The smaller magnet assembly is mounted within the center of the magnetic field of the outer bell housing.
When the pump motor is started the outer bell housing begins to rotate. As the outer bell rotates, the rotating magnetic field effects the inner impeller magnet. As the two magnets begin to turn together, the impeller begins turning and displacing fluid.
