In stirring systems and pumps, they ensure complete separation of the drive and driven sides, reliably sealing critical liquids and gases. They effectively prevent potentially serious leaks, offering a reliable alternative to conventional dynamic shaft seals.

Various dimensions and magnet types allow for the attainment of different torques. To avoid eddy current losses, it is advisable to use a PEEK or ceramic spacer. In addition to standard models of magnetic couplings, they are also available as end-face couplings or hysteresis couplings.
