1. General description
The SQ/SQE is a 3 inch diameter submersible pump
mainly designed for the pumping of raw water in do-
mestic water supply. This manual is designed to assist
in the proper set-up, installation and operation of
these pumps.
1.1 Applications
Typical applications are:
• residential housing
• small waterworks
• pressure boosting
• irrigation systems
• liquid transfer in tanks.
2. Preinstallation
2.1 Well preparation
If the pump is to be installed in a new well, the well
should be fully developed and bailed or blown free of
cuttings and sand.
The construction of the Grundfos SQ/SQE submersi-
bles makes them resistant to abrasion; however, no
pump made of any material can forever withstand the
destructive wear that occurs when constantly pump-
ing sandy water.
If this pump is used to replace an oil-filled submers-
ible or oil-lubricated line-shaft turbine in an existing
well, the well must be blown or bailed clear of oil.
2.2 Make sure you have the right pump
Determine the maximum depth of the well and the
drawdown level at the maximum pump capacity.
Pump selection and setting depth should be made
based on this data.
2.3 Pumped liquid requirements
Submersible well pumps are designed for pumping
clear, cold water; free of air or gases. Decreased pump
performance and life expectancy can occur if the wa-
ter is not clear, cold or contains air or gases.
The water temperature should not exceed 104°F.
A check should be made to ensure that the installa-
tion depth of the pump will always be at least three
feet below the maximum drawdown level of the well.
The bottom of the motor should never be installed
lower than the top of the well screen or within five
feet of the well bottom.
Before beginning installation procedures,
these installation and operating instruc-
tions should be studied carefully. The in-
stallation and operation should also be in
accordance with local regulations and ac-
cepted codes of good practice.

2.4 Motor cooling requirements
To ensure proper motor cooling, refer to the table be-
low for minimum flow requirements:
If the pump is to be installed horizontally, e.g. in a
tank, and there is a risk that the pump might be cov-
ered by mud, it must be installed in a flow sleeve.
2.5 Liquid temperatures/cooling
Figure 1 shows an SQ/SQE pump installed in a well.
With the pump operating, figure 1 illustrates the fol-
lowing:
• Well diameter
• Pump diameter
• Temperature of pumped liquid
• Flow past the motor to the pump suction strainer.
Note: The well diameter must be at least 3 inches.
If there is a risk that the motor will be covered with
sediment, it is recommended the pump be placed in a
flow sleeve. The motor should always be installed
above the well screen.
Fig. 1 Pump installed in well
2.6 Motor preparation
Grundfos MS 3 and MSE 3 submersible motors have
water-lubricated slide bearings. No additional lubrica-
tion is required.
The submersible motors are factory-filled with a spe-
cial Grundfos motor liquid, type SML 2, which will pro-
tect the motor liquid down to 4°F (–20°C) and prevent
the growth of bacteria. The level of motor liquid is im-
portant for the operating life of the bearings and con-
sequently the life of the motor.
2.7 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 2.
To refill the motor, proceed as follows:
1. Remove the cable guard and separate the pump
end from the motor.
2. Place the motor in vertical position with an incli-
nation of approximately 10°.
3. Remove the filling plug using a screwdriver or a
similar tool.
4. Inject motor liquid into the motor with a filling sy-
ringe or similar tool, see fig. 2.
5. To allow possible air to escape, move the motor
from side to side and turn the shaft.
6. Replace the filling plug and make sure it is tight.
7. Assemble pump end and motor.
8. Fit the cable guard.
The pump is now ready for installation.

3. Installation positions
3.1 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. 3.
If the pump is to be installed horizontally, e.g. in a
tank, and there is a risk that the pump might be cov-
ered by mud, it must be installed in a flow sleeve.
Fig. 3 Pump position
4. Electrical connection
4.1 General
The electrical connection should be carried out by an
authorized electrician in accordance with local regula-
tions.
The supply voltage, rated maximum current and
power factor (PF) appear on the motor nameplate.
The required voltage for Grundfos submersible
MS 3/MSE 3 motors, measured at the motor termi-
nals, is –10%/+6% of the nominal voltage during con-
tinuous operation (including variation in the supply
voltage and losses in cables).
If the pump is connected to an installation where a
Ground Fault circuit breaker (GFI) is used as additional
protection, this circuit breaker must trip out when
ground fault currents with DC content (pulsating DC)
occur.
Note: The pump must never be connected to a capaci-
tor or to another type of control box than CU 300 or
CU 301.
Note: The pump must never be connected to an exter-
nal frequency converter.
Supply voltage:
1 x 90-120 V or 1 x 200-240 V –10%/+6%, 50/60 Hz.
The current consumption can only be measured accu-
rately by means of a true RMS instrument. If other in-
struments are used, the value measured will differ
from the actual value.
The SQE pumps can be connected to a CU 300 or
CU 301 control box.
4.2 Motor protection
The motor has built-in automatic thermal overload
protection and requires no additional motor protec-
tion.
4.3 Connection of motor
The motor can be connected directly to the main cir-
cuit breaker.
Start/stop of the pump will typically be done via a
pressure switch, see fig. 4.
Note: The pressure switch must be rated for the maxi-
mum amps of the specific pump.
Fig. 4 Wiring diagram
Note: The pump must never be connected to a capaci-
tor or to another type of control box than CU 300 or
CU 301.
TM01 1375 4397
Before starting work on the pump, make
sure that the electricity supply has been
switched off and that it cannot be acciden-
tally switched on.
The pump must be grounded.
The pump must be connected to an exter-
nal mains switch.
Allowed
Not allowed Reduced risk of electric shock during opera-
tion of this pump requires the provision of
acceptable grounding. If the means of con-
nection to the supply connected box is
other than grounded metal conduit, ground
the pump back to the service by connecting
a copper conductor, at least the size of the
circuit supplying the pump.

5. Cable sizing
Single-phase 60 Hz maximum cable length motor service to entrance:
6. Splicing the cable
Splice the drop cable with the motor cable. If the
splice is carefully made, it will be as efficient as any
other portion of the cable and will be completely
watertight.
There are a number of cable splicing kits available to-
day - epoxy-filled, rubber-sealed, etc. Many perform
well if the manufacturer’s directions are followed
carefully. If one of these kits is not used, we recom-
mend the following method for splicing the motor
cable to the drop cable:
1. Examine the motor cable and the drop cable care-
fully for damage.
2. Cut the motor leads off in a staggered manner.
3. Cut the ends of the drop cable so that the ends
match up with the motor leads.
Be sure to match the colors.
4. Strip back and strip off one inch of insulation from
each lead, making sure to scrape the wire bare to
obtain a good connection.
Be careful not to damage the copper conductor
when stripping off the insulation.
5. Insert a properly sized Sta-Kon™-type connector
on each pair of leads, again making sure that col-
ors are matched.
Using Sta-Kon™ crimping pliers, indent the lugs.
Be sure to squeeze down hard on the pliers, partic-
ularly when using large cable.
6. Form a piece of electrical putty tightly around
each Sta-Kon™. The putty should overlap on the
insulation of the wire.
7. Use a good quality tape such as #33 Scotch Water-
proof or Plymouth Rubber Company Slipknot Grey.
Wrap each wire and joint tightly for a distance of
about 2½ inches on each side of the joint.
Make a minimum of four passes over each joint
and overlap each pass approximately one inch to
ensure a completely watertight seal.
Note: Do not lower or lift the pump using the motor
cable.
7. Fitting the cable plug to the motor
The cable plug supplied with the motor is factory-
greased. Check that the plug is greased correctly,
see fig. 5.
Fig. 5 Greasing of plug
To fit the cable plug, proceed as follows:
1. Check that the cable is of the correct type, cross-
section and length.
2. Check that the mains on the location has correct
connection to ground.
3. Check that the motor socket is clean and dry.
4. Press the cable plug onto the motor socket.
The plug will only fit one way, see fig. 6.
5. Fit and tighten the four screws, see fig. 6.
When the plug has been fitted, there must not be
a clearance between the motor and the cable plug.

8. Fitting the cable guard
To fit the cable guard, proceed as follows:
1. Make sure that the motor lead lies flat in the cable
guard.
2. Place the cable guard in the groove in the cable
plug. The two flaps must engage with the upper
edge of the pump sleeve, see fig. 7.
Fig. 7 Placing the cable guard
3. Fasten the cable guard to the pump suction
strainer with the two self-tapping screws sup-
plied, see fig. 8.
Fig. 8 Fitting the cable guard to the pump suction
strainer
9. Piping
• The pump should only be gripped by the two flats
at the top of the pump, see fig. 9.
• The pump can be installed vertically or horizontally.
During operation, the pump must always be com-
pletely submerged in water.
• When plastic pipe is used, a stainless steel safety
wire is recommended for lowering and lifting the
pump. Fasten the wire to the eyelet on the pump,
see fig. 10.
• The threaded joints must be well cut and fit to-
gether tightly to ensure that they do not work
loose.

Maximum 500 feet.
Fig. 10 Installation depth
Procedure:
To install the pump, proceed as follows:
1. Attach the enclosed data plate sticker at the well
head.
2. Check the well for proper clearance. The well must
be at least 3 inches in diameter. It is a good idea to
check the well for clearance using a plumb ring
(2.95 ø x 10 in.).
3. Attach the first section of riser pipe to the pump.
4. Lower the pump into the well. Make sure the mo-
tor cable is not damaged when the pump is lifted
or lowered into the well, especially in 3 inch wells.
Note: Do not lower or lift the pump using the mo-
tor cable.
5. When the pump has been installed to the required
depth, the installation should be finished by
means of a well seal.
Note that the dynamic water level should always
be above the pump.
6. Loosen the safety wire so that it becomes un-
loaded and lock it to the well seal using a cable
clamp.
7. Complete the electrical connections.
Note: The pump must never be connected to a capaci-
tor or to another type of control box than CU 300 or
CU 301.
Installation depths:
Maximum installation depth:
500 feet below the static water level.
Minimum installation depth:
1.75 feet below the dynamic water level.
Vertical installation:
During start-up and operation, the pump must always
be completely submerged in water.
Horizontal installation:
The pump must be installed at least 1.75 feet below
the dynamic water level.
If there is a risk that the pump might be covered by
mud, the pump must always be placed in a flow
sleeve.
Note: Do not lower or lift the pump using the motor
cable.
11. Generator operation
It is safe to operate the SQ/SQE with a generator.
The generator must be sized 50% above the P1 (input
power) values of the pump. See the following table.

12. Starting the pump for the first time
When the pump has been connected correctly, the
pump should be started with the discharge valve
closed approximately one third.
Due to the soft start feature, the pump takes approxi-
mately 2 seconds to develop full pressure.
12.1 Motor cooling and other considerations
• Make sure the well is capable of yielding a mini-
mum quantity of water corresponding to the pump
capacity.
• Do not start the pump until it is completely sub-
merged in the liquid.
• As the valve is being opened, the drawdown should
be checked to ensure that the pump always re-
mains submerged.
• To ensure the necessary cooling of the motor, the
pump should never be set so low that it gives no
water.
If the flow rate suddenly falls, the reason might be
that the pump is pumping more water than the
well can yield. The pump must immediately be
stopped and the fault corrected.
12.2 Impurities in the water
If there are impurities in the water, the valve should
be opened gradually as the water becomes clearer.
The pump should not be stopped until the water is
clean, otherwise the pump parts and the check valve
may become clogged.
When the water is clean, the valve should be fully
opened.
12.3 Minimum flow rate
To ensure the necessary cooling of the motor, the
pump flow rate should never be set to a value lower
than 0.2 gpm.
If the flow rate suddenly falls, the reason might be
that the pump is pumping more water than the well
can yield. The pump must immediately be stopped
and the fault corrected.
Note: The pump’s dry-running protection is effective
only within the recommended duty range of the
pump.
Note: Do not let the pump run against a closed dis-
charge valve for more than 5 minutes. When the dis-
charge valve is closed, there is no cooling flow and
there is a risk of overheating in motor and pump.
12.4 Built-in protection
The motor incorporates an electronic unit which pro-
tects the motor in various situations.
• In case of overload, the built-in overload protection
will stop the pump for 5 minutes. After that period,
the pump will attempt to restart.
• If the pump has been stopped as a result of dry run-
ning, it will start automatically after 5 minutes.
• If the pump is restarted and the well has not recov-
ered, the pump will stop after 30 seconds.
12.5 Resetting the pump
Switch off the electricity supply for 1 minute.
The motor is protected against the following condi-
tions:
• dry running
• voltage surges (up to 6000 V)
In areas with high lightning intensity, external
lightning protection is required.
•overvoltage
• undervoltage
•overload
• overtemperature.
12.6 MS 3 motors
Note: All MS 3 motors are factory-set to detect dry-
running conditions.
Check that the combination of pump and motor corre-
sponds to the data on page 39.
12.7 MSE 3 motors
Note: All MSE 3 motors are factory-set to detect dry-
running conditions. However, if the maximum pump
speed setting is changed, the dry running stop value
must also be changed. Please refer to either the
CU 301 or CU 300 I&O for instructions on this proce-
dure.
12.8 Maintenance and service
The pumps are normally maintenance-free.
Deposits and wear may occur. For that purpose, ser-
vice kits and service tools are available from
Grundfos.
The Grundfos Service Manual is available on request.
The pumps can be serviced at a Grundfos service cen-
ter.

13. Assembly of pump and motor
To assemble pump end and motor, proceed as fol-
lows:
1. Place the motor horizontally in a vice and tighten
it, see fig. 12.
2. Pull the pump shaft out to the position shown in
fig. 11.
Fig. 11 Pump shaft position
3. Grease the motor shaft end with the grease sup-
plied with the motor.
4. Screw the pump end on the motor (55 Nm).
Note: The pump shaft must engage with the mo-
tor shaft.
A spanner may be used on the clamping faces of
the pump end, see fig. 12.
5. Fit the cable guard as described in section 8.

14. Troubleshooting
Fault Cause Remedy
1. The pump does
not run.
a) The fuses are blown. Replace the blown fuses. If the new fuses
blow too, check the electrical installation
and the drop cable.
b) The GFI circuit breaker has tripped. Reset the circuit breaker.
c) No electricity supply. Contact the electricity provider.
d) The motor protection has cut off the
electricity supply due to overload.
Check for motor/pump blockage.
e) The drop cable is defective. Repair or replace the pump/cable.
f) Overvoltage has occurred. Check the electricity supply.
2. The pump runs but
gives no water.
a) The discharge valve is closed. Open the valve.
b) No water or too low water level in
well.
Increase the installation depth of the pump,
throttle the pump or replace it with a
smaller capacity model.
c) The check valve is stuck in its closed
position.
Pull the pump and clean or replace the
valve.
d) The suction strainer is closed. Pull the pump and clean the strainer.
e) The pump is defective. Repair or replace the pump.
3. The pump runs at
reduced capacity.
a) The drawdown is larger than
anticipated.
Increase the installation depth of the pump,
throttle the pump or replace it with a
smaller capacity model.
b) The valves in the discharge pipe are
partly closed/blocked.
Check and clean or replace the valves as
necessary.
c) The discharge pipe is partly choked
by impurities (iron bacteria).
Clean or replace the discharge pipe.
d) The check valve of the pump is
blocked.
Pull the pump and clean or replace the
valve.
e) The pump and the riser pipe are
partly choked by impurities
(iron bacteria).
Pull the pump. Check and clean or replace
the pump, if necessary. Clean the pipes.
f) The pump is defective. Repair or replace the pump.
g) Hole in discharge pipe. Check and repair the piping.
h) The riser pipe is defective. Replace the riser pipe.
i) Undervoltage has occurred. Check the electricity supply.
4. Frequent starts
and stops.
a) The differential of the pressure
switch between the start and stop
pressures is too small.
Increase the differential. However, the stop
pressure must not exceed the operating
pressure of the pressure tank and the start
pressure should be high enough to ensure
sufficient water supply.
b) The water level electrodes or level
switches in the reservoir have not
been installed correctly.
Adjust the intervals of the electrodes/level
switches to ensure suitable time between
the cutting-in and cutting-out of the pump.
See installation and operating instructions
for the automatic devices used. If the
intervals between start/stop cannot be
changed via the automatics, the pump
capacity may be reduced by throttling the
discharge valve.
c) The check valve is leaking or stuck
half-open.
Pull the pump and clean or replace the
check valve.
d) The supply voltage is unstable. Check the electricity supply.
e) The motor temperature is too high. Check the water temperature.
