2. Symbols used in this document

The MQ water supply system is designed for these

typical applications:
water pressure boosting
(maximum inlet pressure: 40 psi)
water supply from wells
(maximum suction lift: 25 ft), for example
in private homes
on farms
in market gardens and other large gardens.
The pump is suitable for rain water.

5.1 Pumped liquids

3. Introduction
The MQ is a low-noise water supply system
consisting of pump, motor, pressure tank and
controller combined into one compact unit.
The system is suitable for both indoor and outdoor
use.
The self-priming pump starts automatically when
water is consumed in the installation and stops when
consumption ceases. The internal, built-in non-return
valve prevents backflow during priming and
operation.
The MQ pump incorporates overtemperature and
dry-running protection as well as a user-friendly
control panel.
The built-in pressure tank reduces the number of
starts and stops in case of leakage in the installation.

Thin, clean, non-aggressive liquids, not containing

solid particles or fibres.

4. Items supplied

7.1 Suction lift

The maximum suction lift of the pump can be
determined from the diagram, page 19.
Example:
If the suction lift is 10 ft, the length of the suction pipe
must not exceed 72 ft.

To prevent movement and vibrations, the pump and

base plate can be secured to a solid foundation by
means of the bolt holes in the base plate.
For pipework connection, see section 8.4 Pipework.
The bolt holes are covered by a thin plastic layer that
must be knocked out before use. See fig. 3.

8.1 Location
The pump is suitable for indoor and outdoor
installation. It is resistant to sunlight.

Note

For outdoor installation, the pump

must be fitted with a protective cover
(accessory). See section 8.5 Protective
cover and 14. Accessories.

Caution

Should the unlikely event of an internal

leakage occur, pumped liquid will be
drained out from the base and/or end
cover instead of damaging the pump.
Install the pump in such a way that no
undesirable collateral damage can
arise.

8.2 Foundation

TM05 5156 3412

Mount the pump on the base plate with horizontal

suction port and vertical discharge port.

Being self-cooling, the pump requires no space or

ventilation at the sides.

TM 044272 1009

Ensure that the maximum ambient

temperatures do not exceed the values
stated in section 7. Operating
conditions.

8.4 Pipework
Note

Never use unnecessary force when

connecting the pipes.

TM01 9698 2600

The pump is supplied with 1" NPT screwed

connections. Fit the connections in the suction and
discharge ports. See fig. 6. The pump discharge port
is flexible, 5 , to facilitate the fitting.

8.3 Space requirement

8.5 Protective cover

8.4.3 Long suction pipes

A separate non-return inlet valve is supplied with the
pump. In case of long suction pipes, we recommend
to fit the non-return inlet valve in the pump suction
port. See section 8.4.4 Fitting of the non-return inlet
valve
The pipes must be adequately supported on either
side of the pump to avoid straining the pump
connections.

The protective cover protects the control panel

against the weather. It is available as an accessory.
See section 14. Accessories.
To fit the protective cover, click the cover onto the
top of the control panel so that it engages with the
top cooling ribs.
To remove the cover, pull the two clips outwards, free
of the cooling ribs, and pull the cover upwards.

Note

Applications with positive inlet

pressure do not require installation of
the non-return inlet valve due to the
fact that the MQ pump incorporates an
internal non-return valve at the
discharge side.

Fig. 10

Fitting of non-return inlet valve

Note

Failure to use the protective cover in

outdoor installations will invalidate the
warranty.

TM04 3745 5008

8.4.4 Fitting of the non-return inlet valve

The non-return inlet valve reduces the risk of losing
pump priming in negative suction applications and
improves the auto-aspiration capability, for example
in water supply from a cistern.
Install the non-return inlet valve as follows,
see fig. 10:
1. Remove the suction connection of the pump.
2. Fit the non-return inlet valve into the suction port
in the direction shown in fig. 10.
3. Refit the pump connection.

TM04 4121 0809

Under normal operating conditions, the pump is

maintenance-free. However, it is recommended to
keep the pump clean.

Fig. 19

Removing the end-cover plug

12. Service
Note

If a pump has been used for a liquid

that is injurious to health or toxic, the
pump will be classified as
contaminated.

If Grundfos is requested to service the pump,

Grundfos must be contacted with details about the
pumped liquid, etc. before the pump is returned for
service. Otherwise Grundfos can refuse to accept
the pump for service.
Possible costs of returning the pump are paid by the
customer.
However, any application for service (no matter to
whom it may be made) must include details about
the pumped liquid if the pump has been used for
liquids which are injurious to health or toxic.

The seal faces are lubricated by the pumped liquid,

meaning that there may be a certain amount of
leakage from the shaft seal.
When the pump is started up for the first time, or
when a new shaft seal is installed, a certain run-in
period is required before the leakage is reduced to
an acceptable level. The time required for this
depends on the operating conditions, i.e. every time
the operating conditions change, a new run-in period
will be started.
Under normal conditions, the leaking liquid will
evaporate, which means that no leakage will be
detected.

16. MQ frequently asked questions

1. What causes the MQ to start?
Answer: The MQ is equipped with both an
internal flow switch and pressure switch. Each of
these can turn the MQ on, depending on water
consumption. The pump will start when:
The flow rate is greater than 0.3 gpm
OR
the pressure is below 29 psi.
2. What causes the MQ to stop?
Answer: Other than the manual on/off button,
only the flow switch is authorized to automatically
stop the MQ during normal operation when flow
drops below 0.3 gpm. The pump will shut off in
12-15 seconds after flow stops.
Additionally, the MQ will be turned off in the event
of a dry-run or overtemperature alarm.

6. What is the maximum inlet pressure allowed

in the MQ?
Answer: For both MQ 3-35 and MQ 3-45, the
maximum internal pressure allowed is 109 psi.
The maximum inlet pressure when added to the
MQ pressure must not exceed 109 psi.
Remember that inlet pressure adds to the MQ
pressure, so with a 40 psi inlet pressure supplied
to the MQ 3-45, internal pressures can reach
approximately 105 psi (65 + 40 psi).
Additionally, if inlet pressures exceed the built-in
pressure switch activation point (28-30 psi
factory setting), the pressure switch will be
unable to activate, and the ability to turn the MQ
on at low flow rates will be lost. In this situation,
only the flow switch will be able to turn the MQ on
at flow rates above its activation point of 0.3 gpm.
7. What is the priming capacity of the MQ?
Answer: Approx. 1.2 gallons.

3. What is the maximum height of a tap above

the MQ?
Answer: If a tap or faucet is installed at heights
greater than 50 ft above the MQ, there is the
potential risk that the MQ will never start.
In cases where the MQ starts due to low pressure
(low flow rates), the pressure has to fall below
the pressure switch activation point (28-30 psi
factory setting). To allow for the pressure of 50 ft
of water, tolerances and a safety margin, we
recommend a maximum height of 50 ft between
the MQ and any tap.

8. How is overload temperature/overtemperature

of the MQ detected?
Answer: The motor has a thermal switch
incorporated in the motor windings.
The switch will cut out the motor and start again.
See the table below.
Thermal protection

Cut-out
4. What is the purpose of the built-in pressure
tank?
Answer: The built-in pressure tank comes from
the factory, pressurized at approximately 23 psi
(with the pump pressure at zero) and holds a
volume of 14 ounces of water. It is designed to
minimize motor startup due to small leaks.

9. Where can a pressure gauge be easily

installed to measure the discharge pressure?
Answer: In the discharge piping or in 3/8" GAS
straight thread opening used to add priming
water to the pump.

5. How is the dry-run condition determined?

17. Disposal
Answer: The dry-run alarm is declared when the
motor is running AND the flow rate is less than
1.6 gpm AND when pressure is less than the
pressure switch setting. When this condition lasts
for 12 seconds, the alarm will be declared after
1 minute, and the motor is stopped. The MQ
attempts to automatically restart every
30 minutes for a maximum of 24 hours. If more
than 24 hours pass without water, the pump must
be restarted manually.
