1.1 Applications
The GRUNDFOS KP 150, KP 250 and KP 350
pumps are single-stage submersible pumps de-
signed for pumping grey wastewater.
Pumps with float switch:
The pump is capable of pumping water which con-
tains a limited quantity of solids up to 10 mm in diam-
eter without being blocked or damaged.
The pump is suitable for automatic as well as manual
operation and can be installed in a permanent instal-
lation or used as a portable pump.
The pump is suitable for:
• pumping of wastewater from washing machines,
baths, sinks, etc. from low-lying parts of buildings
up to sewer level.
• drainage of cellars or buildings prone to flooding.
• pumping in draining wells.
• pumping in wells for surface water with inlets from
roof gutters, pits, tunnels, etc.
• emptying swimming pools, ponds or fountains.
Pumps with vertical level switch:
The pump must only be used for the pumping of
clean ground water and drain water.
General:
The pump is not suitable for pumping:
• liquids containing long fibres;
• inflammable liquids (oil, petrol, etc.);
• aggressive liquids.
Note: The pump contains approx. 70 ml of non-
poisonous motor liquid that may pollute the pumped
liquid if the pump should leak.
1.2 Operating conditions
Liquid temperature:
Minimum 0°C. The maximum liquid temperature
depends on the rated voltage of the pump, see the
table below.
* Voltage variant for KP 350
