• Damage to the environment and personal injury
from leakage of harmful substances.

1.3 Safety instructions for the operator/

user

The safety instructions described in these
instructions, existing national regulations on health
protection, environmental protection and for accident
prevention and any internal working, operating and
safety regulations of the operator must be observed.

Information attached to the pump must be observed.
Leakages of dangerous substances must be

disposed of in a way that is not harmful to the
personnel or the environment.

Damage caused by electrical energy must be
prevented, see the regulations of the local electricity
supply company.

Before starting work on the pump, the
pump must be disconnected from the
mains. The system must be
pressureless!

The mains plug is the separator
separating the pump from the mains.

Only orginal accessories and original spare parts
should be used. Using other parts can result in
exemption from liability for any resulting
consequences.

1.4 Safety of the system in the event of a

failure in the dosing pump

The dosing pump was designed according to the
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.

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).

Observe the chemical manufacturer's
safety data sheets and safety
instructions when handling chemicals!

A deaeration hose, which is routed into
a container, e.g. a drip tray, must be
connected to the deaeration valve.

The dosing medium must be in liquid
aggregate state!

Observe the freezing and boiling points
of the dosing medium!

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.

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 user­friendly control panel which gives access to the
pump functions.

2.1 Applications

The DME dosing pump is designed for handling
chemicals within the following ranges of applications,
among others:

• drinking water treatment

• wastewater treatment

• cooling water treatment

• washing systems

• process water treatment

• chemical industry.

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
button until residual chemical has been removed.
Note: When the buttons 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 the installation example in section 4.4.

• Note: 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.

• 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.

• Tighten the dosing head after 2 to 5 operating
hours (torque 5.5 Nm).

• 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 in the dosing head
points downwards, see fig. 1.
Note: It is important that the drain pipe/hole is
not inserted direct into the tank contents, as
gasses may penetrate into the pump.

4.4 Installation example

The drawing in fig. 2 shows an installation example.

The DME pump can be installed in many different ways. The sketch below shows an example with side­fitted control panel. The tank is a Grundfos chemical tank with a Grundfos level control unit.

Fig. 2

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 3.2.

• Do not lay signal cables, if any, together with
power cables.
