Scrapers

Scrapers

Wipers are installed in hydraulic and pneumatic cylinders to wipe off dirt, foreign particles, chips, ice, moisture etc. from the piston bar. This prevents contamination of the medium and protects seals, guides and other components.

Standard profiles

The standard profiles shown below are wipers that represent the state of the art. We manufacture these standard wipers in-house or supply them as moulded parts from approved partners for all required groove dimensions in a variety of materials. Depending on the quantity, the material and your requirements, we offer wipers in the appropriate manufacturing process – everything from one 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 wiper system can be adapted to a specific application. To choose the right profile and the optimal material, the following criteria are vital:

  • installation space
  • temperature range
  • medium
  • lifting speed
  • counter surface
  • installation option
  • friction behaviour
  • service life expectancy
  • price and availability
