The main component of the MINEX®-S is the containment shroud that is fixed to the driven-sided power unit and separates internal and external rotor from each other. It ensures a low-vibration torque transmission working without mechanical connection and guarantees a completely leak-proof separation of product and atmosphere. The sealing is achieved with a flat seal or an o-ring, thus eliminating the need to dynamically load the sealing elements.

The material ceramics does not generate any eddy current losses so that the selection torque of the coupling can be reduced by 10 to 15 %.  Since a generation of heat in the coupling caused by the containment shroud material does not have to be expected, ceramics is excellently suitable for dry-running applications such as vacuum pumps, compressors or fan drives as well as agitators, PU plants, etc.

 

Depending on the size, the MINEX®-S types with containment shroud made of ceramics can be used up to 25 bar and 300 °C.
