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