Staufix FKA automatic backwater valve

DN 125, Floor slab, tileable

The Premium automatic backwater valve for faecal and faecal-free wastewater is equipped with a motor-driven closure system which is closed automatically in the event of backwater. A second closure system serves as an emergency closure to be closed by hand. The station is controlled by a user-friendly control unit, which is optionally integrated in the building management system via a potential-free contact, or alarm and collective fault messages can be output via a GSM interface. Thanks to the modular KESSEL system, existing systems can easily be converted to a Pumpfix F backwater pumping station.

  • Safe, motor-driven closure system with optical probe
  • Fast, simple and toolless maintenance
  • Available as a complete set or module set
