Producer in the pharmaceutical industry

Worst-case scenario. Planned weekend repair of a plant by foreign specialist mechanics cannot be completed. A highly cost-intensive postponement is imminent, the timely resumption of production is in danger.

Delicacies manufacturer

Expensive maintenance.  A complete piston of a filling line has a short service life and has to be changed often. This generates high costs due to plant downtime and costly procurement.

Automotive supplier

No room for a standard solution. Due to limited space, no standard size of the desired EMR series fits.

Vacuum generator

Leakage at joints. Due to typical production-related tolerances while manufacturing joint-vulcanized o-rings in the desired size, small but problematic leaks are occuring in the vacuum unit.

Breathing tube

Leakage caused by pressurisation. The standard O-rings used lose the necessary pre-tension due to the strong breathing of the pipe.
