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 housing
Pump housing with an outstanding design for
submersible wastewater pumps, resulting in a high
head.
The pump housing is made of a steel tube with a
smooth surface and a hydraulically correct shape
ensuring free passage of particles.
Ring stand, pump inlet and pump housing are fastened
to the motor by means of four springs enabling quick
and easy dismantling.
Discharge port
All Unilift AP35B pumps have a threaded 2" NPT
horizontal 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 1.4" in the pump
housing. The blades are curved backwards to reduce
any harmful effect from solid particles and to minimize
power consumption. The impeller has a protective cap
to prevent the deposit of long-fibered material.
