not avoided, could result in death or seri-
ous personal injury.
CAUTION
Indicates a hazardous situation which, if
not avoided, could result in minor or mod-

The text accompanying the three hazard symbols
DANGER, WARNING and CAUTION is structured in
the following way:
SIGNAL WORD
Description of the hazard
Consequence of ignoring the warning
• Action to avoid the hazard.
A blue or grey circle with a white graphical
symbol indicates that an action must be
taken.
A red or grey circle with a diagonal bar,
possibly with a black graphical symbol, in-
dicates that an action must not be taken or
must be stopped.
If these instructions are not observed, it
may result in malfunction or damage to the
equipment.
Tips and advice that make the work easier.

3. General
WARNING
Electric shock
Death or serious personal injury
‐The pump must not be used when peo-
ple are in the water.
In the section A.1. Appendix of these installation and
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/m3. 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.

4.1 Storage
Storage temperature: -20 °C to +60 °C.
4.1.1 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.
4.2 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.

English (GB)

5. Preparation
Grundfos MS 3 and MSE 3 submersible motors have
water-lubricated slide bearings. No additional
lubrication is required.
The submersible motors are factory-filled with a
special Grundfos motor liquid (type SML 3), which is
frost-proof down to -20 °C and preserved to prevent
the growth of bacteria.
The level of motor liquid is decisive for the operating
life of the bearings and consequently the life of the
motor.
5.1 Refilling of motor liquid
If for any reason the motor liquid has been drained or
lost, the motor must be refilled with Grundfos motor
liquid SML 3.
To refill the motor, proceed as follows:
1. Remove the cable guard and separate the pump
part from the motor.

TM029606
Refilling of motor liquid
2. Place the motor in vertical position with an
inclination of approx. 10 °.
3. Remove the filling plug using a screwdriver or a
similar tool.
4. Inject motor liquid into the motor with a filling
syringe or the like.
5. To allow possible air to escape, move the motor
from side to side.
6. Refit the filling plug and make sure it is tight.
7. Assemble pump part and motor.
8. Refit the cable guard.
The pump is now ready for installation.
5.2 Positional requirements
The pump is suitable for vertical as well as horizontal
installation, however, the pump shaft must never fall
below the horizontal plane. See fig. Positional
requirements of the pump.

Positional requirements of the pump
Pos. Description
1 Allowed
2 Not allowed
If the pump is to be installed horizontally, e.g. in a
tank, and there is a risk that the pump might be
covered by mud, it must be fitted in a flow sleeve.
For installation depths, see section Installation
depths.

5.3 Liquid temperatures/cooling
Figure SQ/SQE pump in a borehole shows an
SQ/SQE pump installed in a borehole. The pump is
operating.
Figure SQ/SQE pump in a borehole illustrates the
following:
• borehole diameter
• pump diameter
• temperature of pumped liquid
• flow past the motor to the pump suction strainer.

TM010518
SQ/SQE pump in a borehole
Pos. Description
1 Liquid temperature
2 Borehole diameter
3 Pump diameter
To ensure sufficient cooling of the motor, it is
important to observe the maximum liquid temperature
of 35 °C under all conditions.
The borehole diameter must be at least 76
mm (approx. 3").
The motor should always be installed above the well
screen. If a flow sleeve is used, the pump may be
installed freely in the borehole.
Do not let the pump run against a closed
discharge pipe for more than 5 minutes.
When the discharge pipe is closed, there
is no cooling flow and there is a risk of
overtemperature in motor and pump.
If the actual temperature of the pumped liquid
exceeds the specified value or the operating
conditions otherwise fall outside the specified
conditions, the pump may stop. Please contact
Grundfos.
