Wilo-DrainLift S

Design

Compact sewage lifting unit with integrated pump

Application

Complete sewage lifting unit ready for connection in accordance with DIN EN 12050-1.

For the pumping of raw sewage that cannot be piped to the sewer system through the use of natural inclines. Wilo-DrainLift S meets the requirements of DIN EN 12050-1 and DIN EN 12056. Minimum dimensions, combined with space-optimised installation area enable a wide range of different application options for:

  • Retrofitting installation of showers, toilets, saunas, etc.
  • Installation of toilets in basement flats
  • Expansion/renovation of flats and buildings
  • Innovative combination of different installation options for sewage lifting units in a single system, e.g.:
    • Direct toilet connection
    • Drainage of individual rooms
    • Front wall installation/recessed wall installation

Can be used in the following installation types:

As conventional sewage lifting unit for connection of a wall-mounted or stand-alone toilet or for complete room drainage. Due to compact design, system requires only minimum space.
In conjunction with front wall installation/recessed wall installation, used as sewage lifting unit, integrated into commercially available front wall installation systems, in recessed wall installation as well as in pedestal profiles.

Note:

It must be possible to both install and remove the system after laying tiles. Observe installation instructions and accessories.
