The lifting unit is provided with a variety of horizontal/vertical inlet nozzles (1). The
hydraulic system (3) pumps the fluid handled into the vertical discharge line (8).
The fluid to be handled flows into the lifting unit through horizontal/vertical inlet
nozzles (1) and is collected in a gas, odour and water-tight plastic tank (10).
Controlled by a level sensor (2) and control unit, either one or two pumps (3) are
started up automatically as soon as the defined fill level is reached. The fluid is
pumped off to a level above the flood level, towards the public sewer.
DANGER
Flooding of control unit
Danger of death from electric shock!

Waste water, e.g. from heat recovery systems
Waste water from swimming pools (increased chlorine concentration)
Waste water with salt content (e.g. seawater)
4.8 Collecting tank
The collecting tank is designed for unpressurised operation: The waste water is
stored in the tank in unpressurised condition and is then pumped into the sewer
system.
The table below indicates the effective tank volume as a function of the inlet nozzle
level H in mm.
