Field Cases

Air application

Sealing Material

Previously installed piston rings and rider bands of air compressors were made of standard PTFE grades. Service life of wear parts as well as for cylinder liners of the 3rd stage was insufficient. Piston rings, rider bends, packing internals and liners suffered from high wear rates.

High-pressure application

SK904 – PEEK with high strength

A dry-running nitrogen compressor for the tobacco industry required at least 8,000 hours of continuous operation. Due to the high pressure in the application, PTFE materials were not suitable. Standard PEEK materials are also at the limits of their performance in this application.
