2. General description

The MQ is a compact water supply system consisting

of a pump, motor, pressure tank and controller

combined in an integral unit.

The pump starts automatically when water is

consumed in the installation and stops when the

consumption ceases. The MQ is a low-noise pump

which can be installed both indoors and outdoors.

The pump is self-priming and has a non-return valve

incorporated in the suction port. See fig. 1.

The pump features a user-friendly control panel.

The pressure tank incorporated in the pump reduces

the number of starts and stops in case of leakage in

the installation.

The MQ pump has built-in overtemperature and

dry-running protection.

2.1 Applications

Typical applications:

• Pressure boosting in storage tanks

(maximum inlet pressure 3 bar) and

• water supply from wells (maximum suction lift

8 metres), e.g.

– in private homes

– in summer and weekend cottages

– on farms

– in market gardens and other large gardens.

The pump can be used for rain water and has been

approved for drinking water.

The maximum suction lift of the pump can be

determined from the diagram on page 261.

Example:

If the suction lift is 2.5 metres, the length of the

suction pipe must not exceed 24 metres.

5. Functions

5.1 Control panel

The MQ pump is operated entirely by means of the

control panel. See fig. 2. The control panel offers the

possibility of starting/stopping the pump. The pump

settings and operating condition are indicated by

indicator lights.

Fig. 2 Control panel

The functions of the control panel are described in the following table:

TM01 9684 2600

Illustration Description

Indicator light (red):

When the indicator light is on, the pump is on standby.

On/off button:

The pump is started/stopped by means of the on/off button.

The on/off button can also be used for manual resetting of an

alarm condition:

• press once for resetting and

• press once more for starting.

Indicator light (green):

Indicates that the pump is ready for operation.

When the indicator light is on, the pump will start automatically

when water is consumed. After-run time depends on the flexibility

of the discharge pipe, but will be at least 10 seconds.

Pump on (green):

The indicator light is on when the pump is running.

English (GB)

5.2 Pump stop

The pump incorporates an electronic protective

function which will stop the pump in case of

• dry running

• overtemperature

• overloaded motor

• seized-up motor/pump.

The pump will restart automatically after 30 minutes

(for 24 hours) in case of any type of fault if the

Auto-reset function is activated (the green indicator

light on the control panel is on. See point 5 in the

table in section 5.1 Control panel).

Auto-reset (green):

As standard, this function is activated on delivery (does not apply

to pump versions for Australia).

• When the indicator light is on, the Auto-reset function is

activated. The pump will automatically attempt to restart every

30 minutes after an alarm/fault over a period of 24 hours.

After this period, the pump will remain in the alarm condition.

• When the indicator light is off, the Auto-reset function is

deactivated. The pump will not restart after an alarm/fault.

The Auto-reset function can be activated/deactivated by pressing

the on/off button for 5 seconds.

Note: When water is consumed, the pump will start and stop

automatically, whether the Auto-reset light is on or off.

Alarm (red):

The indicator light is on when the pump is in alarm condition.

The alarm condition may have been caused by:

• dry running

• overtemperature

• overloaded motor

• seized-up motor/pump.

See section 5.2 Pump stop.

Illustration Description

Note

The pump settings are stored. After supply failure, the pump will automatically revert to its

operating condition when the power supply is connected again.

English (GB)

6. Mounting and connection

6.1 Mounting the pump

The pump is resistant to sunlight and can be

installed both indoors and outdoors. When installed

outdoors, it is recommended to protect the pump by

means of a suitable cover.

Always mount the pump on the base plate with

horizontal suction port and vertical discharge port.

The pump must be mounted horizontally.

Maximum permissible inclination angle: ± 18 °.

See fig. 3.

Fig. 3 Horizontal installation of MQ

The pump must be secured to a solid foundation by

bolts through the holes in the base plate. See fig. 4.

The bolt holes are covered by a thin plastic layer that

must be knocked out before use. See fig. 5.

Fig. 4 Base plate

Fig. 5 Knocking out the plastic layer in bolt

hole

The pump discharge is flexible, ± 5 °, to facilitate the

connection. Never apply unnecessary force when

connecting the pipes.

The pump is supplied with G 1 (50 Hz) or 1" NPT

(60 Hz) screwed connections to be fitted in the

suction and discharge ports. See fig. 6.

and discharge ports
