Magnetic Couplings: Function, Selection & Design

Magnetic Couplings: Contactless and Leak-Free

Magnetic couplings transmit torque contactlessly via a magnetic field — without any mechanical contact between the drive and output sides. This makes them leak-free and low-wear: ideal for pumps, mixers, and metering systems where media purity or explosion protection is a strict requirement.

This knowledge hub page brings together all guides and comparisons on magnetic couplings: from the basic design types — hysteresis coupling and permanent magnet/synchronous coupling — through the containment shell as a hermetic barrier wall, to a direct comparison with the mechanical seal as the traditional shaft sealing solution.
