latest technologies and is carefully manufactured and
tested.
If it fails regardless of this, the safety of the overall
system must be ensured. Use the relevant monitoring
and control functions for this.
WARNING
Chemical hazard
Death or serious personal injury
‐Make sure that any chemicals that are
released from the pump or any
damaged lines do not cause damage
to system parts and buildings.
‐The installation of leak monitoring
solutions and drip trays is
recommended.
1.5 Dosing chemicals
Warning
Before switching the supply voltage back
on, the dosing lines must be connected in
such a way that any chemicals in the
dosing head cannot spray out and put
people at risk.
The dosing medium is pressurised and
can be harmful to health and the
environment.
Warning
When working with chemicals, the
accident prevention regulations applicable
at the installation site should be applied
(e.g. wearing protective clothing).

6
English (GB)

Caution
The dosing medium must be in liquid
aggregate state!
Observe the freezing and boiling points of
the dosing medium!
Caution
The resistance of the parts that come into
contact with the dosing medium, such as
the dosing head, valve ball, gaskets and
lines, depends on the medium, media
temperature and operating pressure.
Ensure that parts in contact with the
dosing medium are resistant to the dosing
medium under operating conditions, see
data booklet!
Should you have any questions regarding
the material resistance and suitability of
the pump for specific dosing media, please
contact Grundfos.
1.6 Diaphragm breakage
If the diaphragm leaks or is broken, dosing liquid
escapes from the drain opening on the dosing head.
Warning
Danger of explosion, if dosing liquid has

2. General description
The Grundfos DME dosing pump is a self-priming
diaphragm pump.
The pump consists of:
• a cabinet incorporating the drive unit and
electronics,
• a dosing head with back plate, diaphragm,
valves, connections and vent valve,
• a control panel incorporating display and
buttons. The control panel is fitted either to the
front or to the side of the cabinet.
The motor is controlled in such a way that the dosing
gets as even and constant as possible, irrespective of
the capacity range in which the pump is operating.
This is carried out as follows:
The speed of the suction stroke is kept constant and
the stroke relatively short, irrespective of the capacity.
Contrary to conventional pumps, which generate the
dosing stroke as a short pulse, the duration of the
dosing stroke will be as long as possible. Thus, an
even dosing without peak values is ensured. As the
pump is always dosing at full stroke length, it ensures
the same high accuracy and suction capability,
irrespective of the capacity, which is infinitely variable
in the ratio of 1:800.
The pump features an LCD display and a user-
friendly control panel which gives access to the pump
functions.
2.1 Applications
The pump is suitable for liquid, non-abrasive, non-
flammable and non-combustible media strictly in
accordance with the instructions in these installation
and operating instructions.
Areas of application (among others)
• drinking water treatment
• wastewater treatment
• cooling water treatment
• washing systems
• process water treatment
• chemical industry.
2.2 Improper operating methods
The operational safety of the pump is only
guaranteed if it is used in accordance with section
Applications.
Warning
Other applications or the operation of
pumps in ambient and operating
conditions, which are not approved, are
considered improper and are not
permitted. Grundfos cannot be held liable
for any damage resulting from incorrect
use.
Warning
The pump must be equipped with a
diaphragm leakage detection when used
for crystallising media.
Warning
The pump is NOT approved for operation
in potentially explosive areas!
Warning
A sunscreen is required for outdoor
installation!

4. Installation
4.1 Safety instructions
• Liquid is under pressure and may be hazardous.
• When working with chemicals, local safety rules
and regulations must be observed (e.g. wear
protective clothes).
• Before starting work on the dosing pump and
system, disconnect the electricity supply to the
pump, ensuring that it cannot be accidentally
switched on. Before reconnecting the electricity
supply, make sure that the dosing hose is
positioned in such a way that any chemical left in
the dosing head is not ejected, thereby exposing
persons to danger.
• If the vent valve in the dosing head is used, it
must be connected to a hose which is led back to
the tank.
• When changing a chemical, make sure that the
materials of the dosing pump and system are
resistant to the new chemical. If there is any risk
of chemical reaction between the two types of
chemicals, clean the pump and system thoroughly
before adding the new chemical. Proceed as
follows: Place the suction tube in water and press
the
100%
button until residual chemical has been
removed.
When the buttons
100%
and are
pressed simultaneously, the pump can
be set to run for a specific number of
seconds at maximum capacity. The
remaining number of seconds will
appear in the display. The maximum
value is 300 seconds.
4.2 Installation environment
• Exposure to direct sunlight should be avoided.
This applies especially to pumps with plastic
dosing heads, as this material can be damaged by
sunlight.
• If the pump is installed outside, an enclosure or
similar protection is required to protect the pump
against rain and similar weathers.
4.3 Installation of pump
• See also section Installation example.
Caution
The dosing head may contain water from
the factory test. If a liquid which must not
come into contact with water is to be
dosed, it is recommended to let the pump
run with another liquid to remove the water
from the dosing head before installation.
Caution
Cross-tighten the dosing head screws with
a torque wrench once before
commissioning and again after 2-5
operating hours at 5.5 Nm (+0.5 / -0 Nm).
• Always install the pump on the supporting foot
with vertical suction and discharge ports.
• Always use suitable tools for the mounting of
plastic parts. Never apply unnecessary force.
• Make sure that the dosing pump and system are
designed in such a way that neither system
equipment nor buildings are damaged in case of
leakage from the pump or rupture of hoses/pipes.
The installation of leakage hoses and collecting
tanks is recommended.
• Make sure that the drain hole (1) in the dosing
head points downwards.
Caution Never attach a hose to the drain opening.

4.5 Electrical connection
• The electrical connection of the pump should be
carried out by qualified persons in accordance
with local regulations.
• For electrical data of the pump, see section
Electrical data.
• Do not lay signal cables, if any, together with
power cables.
Warning
Danger to life due to non-tripping of the
residual current device (RCD)!
If the pump is connected to an electric
installation where a residual current device
(RCD) is used as an additional protection,
this RCD must trip when earth fault
currents with DC content (pulsating DC)
and smooth DC earth fault currents occur.
This means that a RCD type B, sensitive
to universal current, must be used.

In case of diaphragm leakage, the signal from the
sensor generates an alarm and the alarm relay will be
activated. See also section Alarm output and indicator
lights.
For connection of the diaphragm leakage sensor, see
section Connection overview.

5.6 Alarm output and indicator lights
The green and red indicator lights on the pump are used for operating and fault indication.
In control variant "AR", the pump can activate an external alarm signal by means of a built-in alarm relay which
must only be connected to a safety extra low voltage (SELV) connection.
Note Connect the alarm relay only to voltages which comply with the SELV requirements in EN/IEC 60
335-1.
The alarm signal is activated by means of an internal potential-free contact.
The functions of the indicator lights and the built-in alarm relay appear from the table below.
