Disc Magnetic Coupling 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.

How Disc Couplings Work

Disc type couplings consist of two opposing discs with powerful rare earth magnets. The torque applied to one disc is transferred through an air gap to the other disc. Because of its simple flat design, you can have angular misalignment of up to 3º or parallel misalignment up to ¼” and still transmit nearly full rotational torque. You could also fabricate an inexpensive flat barrier to separate the atmospheres or fluids surrounding the two discs. This is our simplest and most versatile coupling.

Advantages of Disc Type Coupling
No Wearing Parts
Synchronous Design, No Slip at Any Speed
No Physical Contact Between Driving and Driven Parts
Simplifies Containment Barrier
Custom Designs Available

Mechanical shaft seals, which separate the drive motor from chemicals in the metering pump, deteriorate over time and cause leaks. Magnetic couplings enclose the drive shaft in an airtight housing. There are no mechanical seals. Permanent magnets in the coupling’s nested rotor system transmit the high drive torque through the coupling enclosure, providing wear-free operation and overload protection. magnetic drive coupling

The airtight, leak-free design makes magnetic couplings an ideal technology for meeting environmental and safety requirements associated with processing the more toxic, aggressive or flammable components used in some polyurethane foam applications.
