Materials

The seal lip material TEDEX – an especially modified PTFE-material – is the most important basis for the Double lip Double lip tandem Double lip outer seal successful application in MultiSeal high-performance seals.

Several simultaneous operating parameters such as pressure and peripheral speed make it necessary to check the limitations of use. The below p×v diagram shows these limitations for TEDEX-B and TEDEX-W. The p×v values are based on full lubrication at an operating temperature of approximately 100°C and for all MultiSeal models up to 10 bar pressure.

Depending on the particular conditions, minor lubrication and dry running make it necessary to considerably reduce the mentioned values and need a coated reverse rotation surface. In such cases we strongly recommend to consult our specialists.

When applying a seal lip, minor friction loss is to be considered.
