Unilift KP
Product description
Fig. 6 Unilift KP
The Unilift KP pump is designed for liquid transfer and
drainage of clean or slightly dirty wastewater with the
pump completely or partly submerged in the liquid.
The pump is suitable for these applications:
• drainage of flooded cellars or buildings
• pumping of domestic wastewater without toilet
waste
• emptying of pools, tanks and vessels
• pumping within agriculture, the dairy industry,
horticulture and the process industry.
Approvals
Pumped liquids
The pumps are suitable for these liquids:
• clean, non-aggressive water
• slightly dirty (grey) wastewater.
If the pump has been used for other liquids than clean
water, it should be flushed through with clean water
immediately after use. The open-impeller construction
ensures a free passage of solids up to a diameter of
0.4".
Operating conditions
During continuous pumping, the suction strainer must
always be completely covered by the liquid.
Max. liquid temperature: 158 °F for periods not
exceeding two minutes at intervals of at least 30
minutes.
Discharge port
Unilift KP 150, KP 250 and KP 350: 1.25" NPT.
Construction
Single-stage, submersible, stainless steel, drainage
pump in a robust design with upward-pointing
discharge port placed on top of the pump.
The water enters the pump through the holes of the
suction strainer, preventing the passage of large
solids. The sturdy impeller has single-curved vanes
with bevelled front edges preventing fibres from
jamming the impeller. The guide vanes in the pump
housing guide the liquid, lifting sand grains into the
liquid flow, thus preventing blocking by sand.
The pump sleeve is made in one piece. The mains
cable enters through a vulcanized and water-tight plug,
which is secured to the socket of the hermetically
sealed stator housing.
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: IP68
Insulation class: F.
The motor incorporates automatic overload protection
which cuts out the motor in case of overload. When
cooled to normal temperature, the motor restarts
automatically.
