Spring-loaded seals

Piston, rod and rotary seals can also be supplied in spring-loaded variants. The seals are particularly well-suited for use in aggressive media and high temperatures. Also, silicone fillings, are interesting applications, especially in the food industry.

Standard profiles

The standard profiles shown below are seals that represent the state of the art. We manufacture these standard seals in-house for all required groove dimensions in a variety of materials. In a diameter range from a few millimetres up to 1.5 metres - you get everything from on source!

Profiles according to customer preferences

If you have conditions which cannot be optimally solved with a standard profile, we can also manufacture an ideal wiper system according to customers’ drawings or develop one. In this field we are a development partner and are perfectly equipped to design the ideal product for you.

Choosing the correct profile

The more information is known, the better a sealing system can be adapted to a specific application. To choose the right profile and the ideal material, the following criteria are vital:

  • installation space
  • pressure range
  • temperature range
  • medium
  • rotary / swivel speed
  • counter surface
  • installation option
  • friction behaviour
  • tightness
  • service life expectancy
  • price and availability
