Transmitting Torque Through Air…

Magnetic couplings offer a non-contact transfer of torque. They are typically used in pumps for seal-less applications; keeping corrosive, toxic, or flammable liquids from escaping into the atmosphere.  

Simple Concept: Opposite Poles Attract. 

This attraction is how we transmit torque from one magnetic hub to another. By driving one magnetic hub, torque is transmitted magnetically to the other magnetic hub. This can be done through the air or through a non-magnetic containment barrier such as stainless steel or fiberglass, allowing complete isolation of the inner magnetic hub from the outer magnetic hub. There are no contacting parts.
