2.1 Applications
6
Grundfos APG pumps are designed for pumping:
6
•
wastewater
6
•
sludge-containing water
6
•
groundwater
7
•
sewage from restaurants, hotels, camping sites,
etc.
7
The compact design makes the pumps suitable for
7
both temporary and permanent installation.
7
Furthermore, the pumps are suitable for free-
8
standing installation as well as installation on an
8
auto-coupling system.

The APG pumps are equipped with a cutter system
which cuts all destructible solids into small pieces so
10
that they can be led away through pipes of a
10
relatively small diameter.

If you order an explosion-proof pump, you
12
will receive a pump not labelled Grundfos.

We must emphasize that we comply with
Note

all obligations with respect to warranty and
service of pumps sold by Grundfos as APG
13
pumps.
Use the explosion-proof APG pump versions for
applications involving a risk of explosion.
The explosion classification of the pumps
is EEx de IIB T4. However, the pumps
Note
must in each individual case be approved
for use at the desired installation site by
the local authorities.
