3. Applications

10
The Grundfos Unilift AP35B and AP50B pumps are
10
single-stage submersible pumps designed for the
11
pumping of wastewater.

The pumps are capable of pumping water containing
a limited quantity of solids without being blocked or
damaged.
Caution:
The pumps are not designed for pumping stones and
similar materials.
The pumps are designed for automatic operation
with float switch and for manual operation. The pump
can be installed in a permanent installation (on auto-
coupling or as a free-standing pump) or used as a
portable pump.
Incorrect use of the pump, for example resulting in
blockage or wear of the pump, is not covered by the
warranty.
