1.1 Applications
9
The SQ and SQE pumps are designed for pumping
9
thin, clean, non-aggressive, non-explosive liquids,
9
not containing solid particles or fibres.
9
Typical applications:
10
•
Groundwater supply for
10
- private housing,
10
- small waterworks,
11
- irrigation systems in for instance green houses.
12
•
Liquid transfer in tanks.
12
•
Pressure boosting.
13
The SQE-NE pumps are designed for pumping thin,
13
clean, non-explosive liquids, not containing solid
13
particles or fibres.
These pumps are suitable for pumping contaminated
or hydrogen-carbonate containing groundwater, e.g.
13
from
14
•
dumps,
14
•
chemical depots,
14
•
industrial areas,
15
•
oil and petrol filling stations,
16
•
environmental applications.
The SQE-NE pumps can also be used for sampling
17
and monitoring and to some extent for incorporation
17
in water treatment systems.
17
Information applying to all pump types:
The maximum sand content of the water must not
exceed 50 g/m³. A larger sand content will reduce
the life of the pump and increase the risk of blocking.
Note: If liquids with a viscosity higher than that of
water are to be pumped, please contact Grundfos.
pH values:
SQ and SQE:
SQE-NE:
Liquid temperature:
The temperature of the pumped liquid must not
exceed 35 °C.
