product description

In collaboration with the TU Dresden university, wks Technik GmbH developed this partially mobile flood protection system, which works reliably, even with high solid-loaded run-off. The tried and tested Mammoth or Air-Lift pump has a particularly large riser diameter which avoids wear and blockages. The driving force is from air blown into the pipe, which displaces the water and carries it upwards. The necessary air can be provided by a fixed or mobile compressor.

This flood protection system is a modular solution adaptable to specific conditions. The development was funded by the German Federal Ministry for Economic Affairs and Energy (Bundes ministerium für Wirtschaft und Energie).

  • Flow rates from 500 to 3,500 m³/h
  • Pipes made of stainless steel
  • Free pipe cross-sectiont


  • Maximum operating reliability, owing to there being no moving parts in the riser which would otherwise result in wearing or blockages
  • Modular, customisable for specific conditions and requirements
  • Long service lifes
  • Ready for use
  • No ATEX approval necessary, as there is no ignition source present
