made of wastewater resistant polyethylene (PE) and
has all necessary ports for the connection of inlet
pipes, outlet pipe, vent pipe and a manually operated
diaphragm pump, which is available as an accessory.
MULTILIFT M, MD, MOG, MDG
The collecting tank has a turnable, eccentric disk in
the back allowing adjustment of the inlet to any height
between 180 and 315 mm above the floor. The most
common heights are marked beside the inlet.
The MULTILIFT M collecting tank offers three
horizontal inlets in the sides (2 × DN 100 and 1 × DN
50) and two vertical inlets at the top of the tank (1 ×
DN 150 and 1 × DN 50). The centres of the horizontal
inlets are 180 mm (DN 50) and 250 mm (DN 150)
above the floor.
The MULTILIFT MD collecting tank offers four
horizontal inlets in the sides (2 × DN 100 and 2 × DN
50) and three vertical inlets at the top of the tank (2 ×
DN 150 and 1 × DN 50). The centres of the horizontal
inlets are 120 mm (DN 50) and 250 mm (DN 150)
above the floor.
The MULTILIFT MOG and MDG collecting tank offers
four horizontal inlets in the sides (2 × DN 100 and 2 ×
DN 50) and two vertical inlets at the top of the tank (1
× DN 150 and 1 × DN 50). The centres of the
horizontal inlets are 115 mm (DN 50) and 250 mm
(DN 150) above the floor.
The side and back inlets 180 and 250 mm above the

Setting to the relevant start inlet level must
be made during startup phase via the
setup menu.
The first step after power supply
connection is a startup phase with level
setting.
To minimise sedimentation, the tank
bottom is chamfered to lead the
wastewater to the pump.

entry. The enclosure class is IP68.
MULTILIFT M, MD, MLD: The length of the cable is
either 4 or 10 m.
