6.2 Applications

The compact design makes the pumps suitable for
both temporary and permanent installation.
The pumps can be installed on an auto-coupling
system or stand freely on the bottom of a pit.
SEG AUTO pumps are portable and designed
ADAPT
for pumping domestic and industrial sewage and
wastewater and thus ideal for use in sparsely
populated areas where gravity sewage systems are
not available.
SEG AUTO pumps are designed with a grinder
ADAPT
system which grinds solid particles into small pieces
so that they can be led away through outlet pipes of
a relatively small diameter.

The product is designed for pumping these liquids:
• domestic wastewater with discharge from toilets
• sewage from restaurants, hotels, camping sites,
etc.

6.4 Potentially explosive environments

Use explosion-proof pumps for applications in
potentially explosive environments.
The pumps must under no circumstances
pump combustible or flammable liquids.
The classification of the installation site
must be approved according to local rules
in each individual case.
The letter X in the certificate number
indicates that the equipment is subject to
special conditions for safe use. The
conditions are mentioned in the certificate
and in these installation and operating
instructions.
Special conditions for safe use of
explosion-proof pumps:
1. Bolts used for replacement must be
class A2-80 or better according to EN/
ISO 3506-1.
2. The pump must not run dry.
3. Make sure the permanently attached
cable is suitably mechanically
protected and terminated in a suitable
terminal board placed outside the
potentially explosive area.
4. The thermal protector in the stator
windings has a rated cutout
temperature of 150 °C guaranteeing
the disconnection of the power supply.
5. The IP68 rating is limited to maximum
10 m submersion depth.
6. The temperature range is limited to -20
to +40 °C for ambient temperature and
0-40 °C for liquids.
7. Contact the manufacturer regarding the
"d" protection type for pumps and for
information on the dimensions of the
flameproof joints.
8. The lock nut of the cable connector
must only be replaced with an identical
one.
