UMAG Magnet used in the Magnetic Drive Pump

SmCo

Magnetic drive pump uses a balanced magnetic field to create the rotation of the fluid impeller. Unlike a traditional centrifugal pump which has a direct drive connection between impeller and motor, a 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. Although these two magnet assemblies are separated by a fluid barrier, the magnetic fields are aligned. When the pump motor is started the outer bell housing begins to rotate. As the outer bell rotates, the rotating magnetic field affects the inner impeller magnet. As the two magnets begin to turn together, the impeller begins turning and displacing fluid.

The magnetic drive pumps are used to transport and manage highly corrosive, environment critical, high-purity and other difficult to manage fluids in the most challenging applications.

You can find Magnetic Drives on various pump types such as end suction centrifugal pumps, self-priming multistage pumps, vacuum pumps, etc. UMAG magnets are using in these pumps for better performance and continuously running.
