MAGNETIC DRIVE PUMP
“Magnetic Drive” refers to the coupling between the wet end of the pump and the motor. In direct drive pumps, the impeller of the pump is attached to the shaft of the motor, and this design depends on the shaft seal to contain the chemical. In a magnetic drive pump, the wet end and motor are two separate contained parts, connected by only a motor bracket.
At the end of the motor shaft, a drive magnet is attached, and as the drive magnet rotates around the rear housing, the impeller, which is fixed upon another magnet, spins in synchronization. Without a shaft seal and the possibility of leakage, magnetic drive pumps excel in applications involving corrosive, toxic, flammable, expensive, or environmentally hazardous liquids.
