Servicing the product 3. Product introduction
Grundfos Liftaway B 40-1 for underfloor installation
is a compact mini lifting station consisting of a tank
and a wastewater pump, type Unilift KP 150, Unilift
KP 250 or Unilift AP12, with level switch for
automatic start/stop. The lifting station is designed
for the pumping of wastewater from wash basins,
washing machines, showers and floor drains. The
Liftaway B 40-1 can also be used for the collection
and pumping of rain water.
The variable height of the tank, which is installed
under the floor, makes it easy to adjust the tank to
floor level.

the wastewater cannot be led directly to the sewer by
means of a natural downward slope.
The lifting station is typically used:
• as draining well for the collection of drainage and
surface water,
• the pumping of wastewater from basements and
laundry rooms below sewer level.
