Magnetic drive technology:

Klaus Union magnetic drive/magnetic coupling technology offers distinct long- and short-term advantages over conventional sealing system. 

This technology does a way with a need for shaft to pass from liquid to non-liquid environments which means that glands and face seal can be dispensed with. The liquid is hermetically sealed in a leakproof, static isolation shell. 

SEALLESS TECHNOLOGY

If pumps are used to handle dangerous products, it is essential to avoid even the smallest leakages into the environment in order to ensure the protection of both people and the atmosphere. The ideal solution for such a case is pumps with magnet drive. The first of its kind was introduced by Klaus Union in 1955.
