be made by children without supervision.

Read this document before you install the

product. Installation and operation must

comply with local regulations and accepted

codes of good practice.

2. Symbols used in this document

DANGER

Indicates a hazardous situation which, if

not avoided, will result in death or serious

personal injury.

WARNING

Indicates a hazardous situation which, if

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-

erate personal injury.

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.

English (GB)

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.

English (GB)

4. Technical data

Operation via generator: As a minimum, the

generator output must be equal to the motor P1 [kW]

+ 10 %.

Starting current

The motor starting current is equal to the highest

value stated on the motor nameplate.

Power factor

PF = 1.

Motor liquid

Type SML 3.

Motor cable

Borehole diameter

Minimum 76 mm.

Installation depth

Maximum 150 m below static water level.

See also section Installation depths.

7.8.2 Installation depths

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.

10°

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.

TM011375

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.
