1.1 Applications

The Grundfos Unilift KP 150, KP 250 and KP 350
pumps are single-stage submersible pumps
designed for pumping grey water.
CAUTION: This pump has been evaluated for use
with water, grey wastewater and heated wastewater.
4
The pump is capable of pumping water which con-
tains a limited quantity of spherical solids up to 3/8"
Page
in diameter without being blocked or damaged.

The pump is suitable for automatic (with float switch)
4
as well as manual operation and can be installed in a
4
permanent installation or used as a portable pump.

diameter
• flammable liquids (oil, gasoline, etc.)
• aggressive liquids.
Note: If the pump has been used for very dirty or
chlorinated water it should be flushed thoroughly
with clean water after use.
The pump contains approx. 70 ml of non-poisonous
motor liquid that may pollute the pumped liquid if the
pump should leak.
