Magnetic Couplings


Magnetic Couplings - How They Work

A magnetic coupling consists of two magnet assemblies. One is the outer assembly (the driver magnet) and the other is the inner assembly (the driven magnet). The outer assembly is connected to a motor and the inner assembly is directly attached to the pump input drive shaft. Since the inner magnet is isolated within the pump case, seals and therefore leaks, are eliminated.

When load (torque) is applied, the coupling deflects angularly and the magnets create a force of simultaneous attraction and repulsion. This force is used to transfer torque from the motor to the pump drive shaft . This permanent magnet coupling creates neither slippage nor induction current during rotation.

The seals for metering pumps, feed pumps and chemical day tank agitators can all be replaced with a permanent magnet coupling to eliminate seal leakage and downtime associated with seal replacement. The inner submerged magnet is of “sealed” construction.
