Wilo-DrainLift SANI CUT-S with non-return valve

The smallest and lightest single-pump system with macerator for detached and semi-detached houses.

The compact Wilo-DrainLift SANI CUT-S single-pump system is the smallest and lightest sewage lifting unit in accordance with EN 12050-1 and is therefore ideal for use in detached and semi-detached houses.

The Wilo-DrainLift SANI CUT-S offers high operational reliability afforded by its large switching volume and the macerator with double shear effect.

With its freely selectable inlets and compact dimensions, the Wilo-DrainLift SANI CUT-S can be flexibly and discreetly installed in a front-wall installation. This makes it ideal for replacing older, existing lifting units.

Maintenance is made particularly easy by the user-friendly construction with transparent cover.

Your advantages

  • Very easy to install, also in concealed wall installation, and to transport due to lightweight and space-saving compact construction 
  • Operational reliability provided by the large switching volume, pump with radial macerator with double shear effect, thermal motor protection and mains-independent alarm
  • Optimised hydraulics/macerator combination for a wide coverage of delivery head at the lowest power requirement for domestic electrical installations
  • Low overall installation costs thanks to the use of smallest possible piping
  • Corrosion-free design with engineering plastics and stainless-steel guarantee's high reliability
