Wilo-DrainLift SANI-S


The ultra-compact and lightest single-pump wastewater lifting unit for one- and two-family houses.
The compact single-pump wastewater lifting unit Wilo-DrainLift SANI-S is the smallest and lightest wastewater lifting unit compliant with EN 12050-1 (without cutting wheel), and therefore ideal for use in single- and two-family houses. The easy-to-install DrainLift SANI-S unit is practically versatile thanks to its large pump volume, selectable air inlets and an optional version for particularly aggressive pumped liquids. The user-friendly design makes maintenance as easy as possible for the user. Thanks to the optional optional radio alarm transmitter, a push message is sent to a smartphone in the event of a malfunction. Maximum ease of installation and transport thanks to ultra-compact design and extremely low weight
