Design The waste water lifting unit consists of a stable collecting tank (1) with integrated
submersible motor pump (6), inlet (2), swing check valve (3) and discharge-side
connection (5).
Function The fluid to be handled flows into the waste water lifting unit through an inlet (2)
and is collected in an odour-tight and water-tight collecting tank (1). When a
specified fluid level is reached, the float switch (4) triggers the automatic start of the
submersible motor pump (6). The fluid handled is pumped through the discharge-
side connection (5) to a level above the flood level and discharged into the public
sewer.
