2. General description
Grundfos SEG pumps are designed with a grinder
system which grinds solid particles into small pieces
so that they can be led away through pipes of a
relatively small diameter.
SEG pumps are used in pressurised systems, e.g. in
hilly areas.
The pumps can be controlled via the Grundfos LC,
LCD 107, LC, LCD 108, LC, LCD 100 pump
controllers or the Grundfos CU 100 control box.
See installation and operating instructions for the
selected unit.

2.2 Applications
•
Pumping of wastewater with discharge from
water closets
•
pumping of 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.
2.3 Operating conditions
The Grundfos SEG range are designed for
intermittent operation (S3). When completely
submerged, the pumps can also run continuously
(S1). See section
.
Installation depth
Maximum 10 metres below liquid level.
Operating pressure
Maximum 6 bar.
Number of starts per hour
Maximum 30.
pH value
Pumps in permanent installations can cope with pH
values ranging from 4 to 10.
Liquid temperature
0 °C to +40 °C.
For short periods (maximum 15 minutes), a
temperature of up to 60 °C is permissible.
Density and viscosity of pumped liquid
When pumping liquids with a density and/or a
kinematic viscosity higher than that of water, use
motors with correspondingly higher outputs.
