MULTILIFT lifting station with controller – family houses – large buildings

Grundfos MULTILIFT lifting stations are advanced, cost-effective solutions designed to collect domestic wastewater inside a building and lift it to a higher level in case sanitary appliances are located below the backwater level.

General Details


The MULTILIFT is perfect for new buildings as well as for retrofit installation.The unit consists of a robust and tight tank, motor(s), level detection, controller and non-return valve. The unit comes preassembled, ready to install.

The proven, reliable system is available as single- as well as two-pump units. With six tank sizes from 44 l to 450 l and up to nine pump sizes for each tank, the unit can be tailored to drain a building of any scale – from the basement of a single-family house up to a huge shopping mall.

Powerful pumps with special hydraulics reliably handle typical solids and fibres from domestic wastewater. Despite the compact footprint of merely 0.25 to 1.6 m2, the units are capable of draining from 1,680 l to 14,400 l per hour.

Thanks to the superior design, service and maintenance costs are down to a minimum.


Located at the basement of any type of building, MULTILIFT lifting stations are suitable for applications such as:

  • protecting sanitary appliances against backwater from sewer system
  • enabling drain where sanitary appliances are located below the drain pipe level or far from downpipe
  • draining entire buildings in hilly locations as a cost-effective alternative to pumping stations
  • draining buildings located far from mains, thus avoiding heavy, costly excavation work for gravity draining
  • discharging wastewater in buildings where basement levels have been converted; MULTILIFT uses the existing drain pipes, and you avoid changing pipes outside the building.
