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
3
exceed 50 g/m
. A larger sand content will reduce
the life of the pump and increase the risk of blocking.
If liquids with a viscosity higher than
Note
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.

3.1 Storage

Storage temperature: -20 °C to +60 °C.

3.1.1 Frost protection

If the pump has to be stored after use, it must be
stored on a frost-free location or it must be ensured
that the motor liquid is frost-proof.
The motor must not be stored without being filled
with motor liquid.

3.2 Sound pressure level

The sound pressure level of the pump is lower than
the limiting values stated in the EC Council Directive
2006/42/EC relating to machinery.
