• emptying ponds, tanks, etc.
Maximum particle size: 0.4".
Liquid temperature range: 32 °F to 131 °F.
Approvals
Operation
The pump can be used for automatic as well as
manual operation and can be installed in a permanent
installation or used as a portable pump.
To enable automatic operation the pump can be fitted
with a float switch or it can be connected to separate
level switch and control box for automatic on/off
operation.
Pump sleeve and housing
The stainless steel pump sleeve is made in one piece
and equipped with an insulated carrying handle. The
suction strainer is clipped on to the pump housing for
easy removal in connection with maintenance. The
strainer prevents the passage of large solids and
ensures a slow flow into the pump. As a result, most
impurities are prevented from entering the pump.
The stainless steel pump housing is fitted with an
internal riser pipe ensuring high efficiency.
The riser pipe has a number of holes enabling efficient
cooling of the motor during operation. The cable entry
is of the socket and plug connection type for quick and
easy dismantling.
Discharge port
All Unilift AP12 pumps have a threaded vertical
discharge port.
Unilift AP12.40: 1.5" NPT.
Unilift AP12.50: 2.0" NPT.
Shaft and bearings
The stainless steel shaft rotates in maintenance-free
prelubricated ball bearings.
Impeller
The stainless steel impeller is a semi-open impeller
with L-shaped blades and a clearance of 0.4". The
blades are curved backwards to reduce any harmful
effect from solid particles and to minimise power
consumption.

Shaft seal
The shaft seal is a combination of a mechanical
bellows shaft seal and a lip seal with 2 fl.oz. oil
between. Seal faces are made of silicone carbide.
