2.1 Applications

SEG pumps are designed for pumping
• domestic wastewater with discharge from toilets
• sewage from restaurants, hotels, camping sites,
etc.
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 the tank.
2.1.1 Potentially explosive environments
Use explosion-proof pumps for applications in
potentially explosive environments.
Warning
The explosion protection classification
of the pump is CE
T4 Gb.
The classification of the installation
site must in each individual case be
approved by the local fire-fighting
authorities.
Warning
The pumps must under no
circumstances pump combustible
liquids.

For short periods (maximum 10 minutes) a
temperature of up to +60 °C is allowed (standard
versions only).

3.6 Density of pumped liquid

Maximum 1000 kg/m
In the case of higher values, see WebCAPS on
