Wilo-DrainLift SANI-M


Large wastewater lifting unit with single pump for one- and two-family houses.

The Wilo-DrainLift SANI-M small wastewater lifting unit is ideal for use in single- and two-family houses with uncontrolled wastewater intake thanks to the single pump with large capacity and the electric motor with selectable "continuous operation" and "intermittent operation" modes. The easy-to-install unit is virtually versatile thanks to its 44 mm to 65 mm free passage, 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 radio alarm transmitter, a push message is sent to a smartphone in case of malfunction.
