Unilift KP-S
Unilift KP is a single-stage, submersible, stainless steel
drainage pump in compact design with hermetically
sealed stator housing (wet runner).
The pump can be installed in a permanent installation or
used as a portable pump. It may be operated fully or
partially submerged.
The pump is suitable for:
• pumping in drain pits
• pumping of wastewater without discharge from
toilets
• drainage of flooded cellars or buildings
• emptying of swimming pools, tanks and fountains
• applications within agriculture, horticulture, dairies,
breweries and the process industry.
Versions
The Unilift KP pump series comes in these versions:
• KP-S with integrated, electronic sensor
(automatic operation)
• KP-A with float switch (automatic operation)
• KP-M without level switch (manual operation).
It is possible to upgrade a Unilift KP-A and a Unilift KP-M,
220-240 V, 50 Hz, to a Unilift KP-S. Contact Grundfos.
Special features of Unilift KP-S
• Compact design - requires a minimum of space
• Automatically self-venting if air is trapped in impeller
• Protected against blocked impeller and dry-running
• Integrated, nanocoded, super-slip, electronic sensor
• Starts even with a 2 mm thick layer of dirt on the
sensor plate.
Approvals
CE, LGA, VDE, GS, EMV, GOST, UL, CSA and

Pumped liquids
The pump is suitable for
• clean, non-aggressive water
• slightly dirty (grey) wastewater.
The open-impeller construction ensures the free passage
of solids up to ø10 mm.
Functions
Unilift KP-S
Automatic start/stop operation by means of a sensor.
The pump starts:
• when the liquid level reaches the sensor plate
• when the pump is connected to the electricity supply
• when the sensor plate is touched with a finger.
The pump stops:
• when the pump starts to suck air (automatic stop)
• if the impeller is blocked.
Unilift KP-A
Automatic start/stop operation by means of a float switch.
Unilift KP-M
Manual operation by means of external start/stop.
Construction
The stainless steel pump sleeve is made in one piece with
Rp 1¼ discharge port and insulating handle. Mains cable
and float switch cable are combined in one vulcanized and
water-tight plug, secured to the socket of the hermetically
sealed stator housing.
Liquid enters the pump through the holes of the suction
strainer. The holes of the strainer prevent the passage of
large solids.
The sturdy impeller has single-curved vanes. The
bevelled front edges prevent fibres from jamming the
impeller.
The guide vanes of the pump housing guide the liquid,
lifting sand grains into the liquid flow. This prevents sand
from blocking the impeller.
Motor
The motor is a single- or three-phase, asynchronous
canned motor with liquid-filled rotor chamber and water-
lubricated bearings. The motor is cooled by the pumped
liquid around the motor.
Enclosure class:
Insulation class:
The motor incorporates automatic overload protection. In
case of overload, the motor stops automatically. When
cooled, the motor restarts automatically.
