Wilo-DrainLift KH 32

Design

Small sewage lifting unit (floor-mounted installation)


Application

Sewage lifting unit ready for connection for limited use (in direct connection behind a stand-alone toilet) with macerator for the disposal of the sewage from an individual toilet in addition to a hand washbasin, a shower or a bidet, the wastewater/sewage of which cannot be conveyed to the sewer system via natural slope and/or for the disposal of wastewater that accumulates below the backflow level. Compliance with DIN EN 12050-3 and DIN 1986‐100 is required. We recommend using Wilo-DrainLift S to XXL as well as FTS series products when connecting several or different drainage fixtures.



Max. pressure pipe lengths DN 32, for optimal operation, the first section of the pressure pipe should be positioned vertically and then the rest continued horizontally if at all possible (2 bends of 90° and a built-in non-return valve are taken into account).
