WARNING
Electric shock
Death or serious personal injury
‐
The pump must not be used when peo-
ple are in the water.
In the section
operating instructions, you will find copies of the
pump and motor nameplates.
Before the SQ/SQE pump is lowered into the
borehole, this page should be filled in with the
relevant nameplate data.
These installation and operating instructions must be
kept in a dry place near the installation site for
reference purposes.
3.1 Applications
The
SQ
and
SQE
pumps are designed for pumping
thin, clean, non-aggressive, non-explosive liquids, not
containing solid particles or fibres.
Typical applications:
•
Groundwater supply for
- private housing
- small waterworks
- irrigation systems in for instance green
houses.
•
Liquid transfer in tanks.
•
Pressure boosting.
The
SQE-NE
pumps are designed for pumping thin,
clean, non-explosive liquids, not containing solid
particles or fibres.
These pumps are suitable for pumping contaminated
or hydrogen-carbonate containing groundwater, e.g.
from
•
dumps
•
chemical depots
•
industrial areas
•
oil and petrol filling stations
•
environmental applications.
The
SQE-NE
pumps can also be used for sampling
and monitoring and to some extent for incorporation
in water treatment systems.
Information applying to all pump types
The maximum sand content of the water must not
exceed 50 g/m
3
. A larger sand content will reduce the
life of the pump and increase the risk of blocking.
If liquids with a viscosity higher than that of
water are to be pumped, please contact
Grundfos.
pH values
SQ and SQE: 5 to 9.
SQE-NE: Please contact Grundfos.
Liquid temperature
The temperature of the pumped liquid must not
exceed 35 °C.
