2. General description
Grundfos pumping stations are pre-fabricated pumping stations
for collection and pumping of drainage water, rainwater or
wastewater.
The pump pit is made of PE-HD (polyethylene) and comes with
discharge pipes and valves fitted.
The pipework is made of PE or stainless steel depending on the
location of the pit and the pumped liquid, and thus the pump
selected.
Unless another solution is selected, the pits up to ∅1000 mm are
supplied with a PE-HD cover which is locked with a special M10 bolt.

3. Applications
14
Grundfos pumping stations are used for collection and pumping
14
of drainage water, rainwater and wastewater. Wastewater is led
14
into the pit. When the liquid in the pit reaches the starting level,
14
the pump will start and pump the liquid further in the system to a
sewage treatment plant or sewer.
The pits are prepared for various pumps depending on the
pumped liquid.
3.1 Pumped liquids
•
Drainage water
•
rainwater (surface water)
•
wastewater.
3.1.1 Liquid temperature
Maximum 40 °C. For higher temperatures, contact Grundfos.
The liquid temperature depends on the pump
Caution
selected. See the installation and operating
instructions of the individual pumps.
3.1.2 Acids and alkalis
The pump pit is resistant to strong acids and alkalis as well as
solvents.
The pumps are supplied with the pump pit and normally stand pH
values between 4 and 10. In case of doubt, contact Grundfos.
3.1.3 Viscosity
Very thick wastewater must not be led into the pit. See also the
installation and operating instructions of the pump.
3.1.4 Density
Maximum 1.1 tons/m

1. Use the public or private waste collection service. 2. If this is not possible, contact the nearest Grundfos company or service workshop. 3. If it is not possible to dispose of the product as a complete unit, the pump installation can be removed from the pit, and the pit can be filled and covered.
