What is Magnetic Disk Coupler ?
Magnetic disk coupler provide a contactless means of torque transfer. They are predominantly utilized in pumps for applications requiring seal-less operation, thereby preventing the escape of corrosive, toxic, or flammable liquids into the atmosphere.
The concept is straightforward: Opposite poles attract. This fundamental principle enables the transmission of torque from one magnetic hub to another. By rotating one magnetic hub, the torque is magnetically conveyed to the companion hub. This transmission can occur through air or via a non-magnetic barrier like stainless steel or fiberglass, achieving complete isolation of the inner from the outer hub. The design excludes any contacting components.
