Product Description

Magnetic coupling
Magnetic coupling is a new kind of coupling, which connects motor and machine by permanent magnetic force
They work in the sealless magnetic drive pumps, which transporting volatile, flammable, explosive and toxic solutions with no leakage
Appearance of magnetic coupling solved thoroughly the leak problems existed in the dynamic sealing of certain mechanical devices
Magnetic coupling is widely used in various industries and fields, such as chemical, papermaking, foodstuff, pharmacy

Magnetic coupling is consisting of the external rotor, internal rotor and isolating cover

Working Theory Outer Rotor

Magnetic couplings are employed in seal-less, leak-free magnetic drive pumps used to handle volatile, flammable, corrosive, abrasive, toxic or foul-smelling liquids
Inner and outer magnet rings are fitted with permanent magnets, hermetically sealed from the liquids, in a multi-pole arrangement 
Inner and outer magnetic rotors are locked together by magnetic forces and work as a synchronous coupling
Permanent-permanent magnetic couplings create neither slippage nor induction current during rotation
When excessive torque is applied, the magnets will decouple, they will not re-couple unless the pump is stopped
Permanent magnetic couplings offer an efficient, leak-proof, cost-effective and more reliable alternative to various conventional sealing methods
