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.
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, allowing for quick
and easy dismantling.
Discharge port
All Unilift AP35 pumps have a threaded 1.5 NPT
vertical discharge port.
Shaft and bearings
The stainless steel shaft rotates in maintenance-free
prelubricated ball bearings.
Impeller
The stainless steel impeller is a vortex impeller with
L-shaped blades and a clearance of 1.38" in the pump
housing. The blades are curved backwards to reduce
any harmful effect from solid particles and to minimise
power consumption. The impeller has a protective cap
to prevent the deposit of long-fibred material.

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.
