Got questions about our products or about wastewater treatment plant equipment?

Do you need help in planning new or refurbishment projects?

Then please give us a call and take advantage of the experience of our capable employees. We will be happy to advise you!


Most of our scraper systems run in continuous operation. That means 24 hours a day, 7 days a week. These extreme conditions can unfortunately always cause failures of individual system components. The result is generally downtime of the entire machinery.

Would you like to.

  • Regular inspection of the scraper devices by the manufacturer is therefore indispensable.
  • This way, worn components can be identified in good time and repaired or replaced.
  • For this reason we recommend that every one of our customers concludes a maintenance contract.
  • The warranty period is thus extended to up to 4 years for new systems.

Repair / optimisation

Convert your scraper to safe winter operation using rail and gear rack?
