eMAG

Magnetic couplings (MAK) are a hermetic, low-maintenance sealing solution for pumps, agitators, and aerators.

Dangerous or precious media remains isolated in the closed system circuit. In turn, nothing penetrates to contaminate the medium.

A special design in combination with a special can as well as high-performance magnets make this magnetic coupling particularly powerful. This means that pumps, for example, can be built much more compactly. The eMAK is specially designed for standard applications up to 25 bar.

Power is transmitted contact-free by magnets from the drive shaft to the product-contacting output shaft. Between the two rotating parts is the containment can, the sealing element, which is bolted to the container. It separates the product space from the atmosphere and hermetically seals it statically.
