Wilo-Rexa MINI3-S
Efficient submersible sewage pump in non-clog design with macerator for house and site drainage for detached and semi-detached houses.
Efficient submersible sewage pump in non-clog design with macerator for house and site drainage for detached and semi-detached houses.
The Wilo-Rexa MINI3-S grinder pump ensures safe house and site drainage. The compact design and the radial macerator with double shear effect allow you to safely drain small pump sumps, such as soakaways or catchment shafts. In addition, using the smallest-possible pipework reduces installation costs. The high-quality motor has a double seal and is easy to maintain. The stainless steel motor housing is corrosion-resistant, even when non-immersed. The low weight and the built-in plug enables easy installation: Simply plug it into the existing socket. Pumps with an attached float switch start automatically. The pumps are switched on and off depending on the fill level.
