product description

In collaboration with the TU Dresden university, wks Technik GmbH has developed a partially mobile flood protection system, which works reliably even if very high solid loads are present. Thanks to the long tried and tested air lift pump principle (also known as the mammoth pump) the riser diameter remains free from movable parts, which could cause wear or blockaging, as in standard pump systems. The driving force is the 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. Thanks to the coordinated components the equipment and process solution has the character of a system. Based on the modular principle, a systemconfigured pumping station with individual delivery rates is provided for the respective assignment. The development was funded by the Bundes ministerium für Wirtschaft und Energie (German Federal Ministry for Economic Affairs and Energy).

constructional features

  • Four coordinated components produce a system solution
    1. Collection shaft
    2. Riser with special air inlet chamber
    3. Mobile compressor with diesel unit or electrical connection
    4. Automation unit with water level sensor
  • Flow rates from 500 to 3,500 m³/h
  • Pipes made of stainless steel
  • Free pipe cross-sectiont


  • Maximum operating reliability, as there are no moving parts in the riser which can be blocked or worn
  • System solutions enables precisely customised components for each use case by applying the modular principle
  • Insensitive to long service lives
  • Ready for use at short notice
  • No ATEX approval necessary, as there is no ignition source present
  • Easy to operate
  • Long use period
  • Low-maintenance
