What is Magnetic Coupling?

Aug 03, 2021

Magnetic couplings are employed in seal-less, leak-free magnetic drive pumps used to handle volatile,flammable, corrosive, abrasive, toxic or foul smelling liquids. The inner and outer magnet rings are fitted with permanent magnets, hermetically sealed from the liquids, in a multipole arrangement.

The inner and outer magnetic rotors are locked together by magnetic forces and work as a synchronous coupling. The permanent-permanent magnetic couplings create neither slippage nor induction current during rotation. When excessive torque is applied, the magnets will decouple, they will not recouple unless the pump is stopped.

Permanent magnetic couplings offer an efficient, leak-proof, cost effective, and more reliable alternative to various conventional sealing methods.
