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.
1.5 Dosing chemicals
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.
When working with chemicals, the accident
prevention regulations applicable at the installation
site should be applied (e.g. wearing protective
clothing and safety goggles).
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.
1.6 Diaphragm leakage
If the diaphragm leaks or is broken, dosing liquid
escapes from the drain opening on the dosing head.
See fig. 3, pos. 14. Observe section 8.4 Diaphragm
leakage.
To avoid any danger resulting from diaphragm
leakage, observe the following:
• Perform regular maintenance. See section
8.1 Regular maintenance.
• Never operate the pump with blocked or soiled
drain opening.
– If the drain opening is blocked or soiled,
proceed as described in section
8.4.1 Dismantling the dosing head, diaphragm
and valves in case of diaphragm leakage.
• Take suitable precautions to prevent harm to
health and damage to property from escaping
dosing liquid.
• Never operate the pump with damaged or loose
dosing head screws.
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.
WARNING
Danger of explosion, if dosing liquid
has entered the pump housing!
Death or serious personal injury
Operation with damaged diaphragm can
lead to dosing liquid entering the pump
housing.
- In case of diaphragm leakage,
immediately separate the pump from
the power supply!
- Make sure the pump cannot be put back
into operation by accident!
- Dismantle the dosing head without
connecting the pump to the power
supply and make sure no dosing liquid
has entered the pump housing. Proceed
as described in section
8.4.1 Dismantling the dosing head,
diaphragm and valves in case of
diaphragm leakage.

3. Product introduction
The DDE dosing pump is a self-priming diaphragm
pump. It consists of a housing with PMS (Permanent
Magnet Synchronous) motor and electronics, a
dosing head with double PTFE diaphragm and
valves and the control cube.
Excellent dosing features of the pump:
• Optimal intake even with degassing media, as
the pump always works at full suction stroke
volume.
• Continuous dosing, as the medium is sucked up
with a short suction stroke, regardless of the
current dosing flow, and dosed with the longest
possible dosing stroke.
3.1 Applications
The pump is suitable for liquid, non-abrasive,
non-flammable and non-combustible media.
Observe the technical data of the product. See
section 4.1 Technical data.
Observe the freezing and boiling points of the dosing
medium.
Make sure that parts in contact with the dosing
medium are resistant to the dosing medium under
operating conditions. See data booklet:
• http://net.grundfos.com/qr/i/99021865.
Should you have any questions regarding the
material resistance and suitability of the pump for
specific dosing media, please contact Grundfos.
A sunscreen is required for outdoor installation.

5.2 Hydraulic connection
The dosing head may contain water from the factory
check. When dosing media which should not come
into contact with water, another medium must be
dosed beforehand.
Faultless function can only be guaranteed in
conjunction with lines supplied by Grundfos.
The lines used must comply with the pressure limits
as per section 4.1 Technical data.
Important information on installation
• Observe suction lift and line diameter. See
section 4.1 Technical data.
• Shorten hoses and pipes at right angles.
• Ensure that there are no loops or kinks in the
hoses.
• Keep inlet line as short as possible.
• Route inlet line up towards the inlet valve.
• Installing a strainer in the inlet line protects the
entire installation against dirt and reduces the
risk of leakage.
• Install a pressure-relief valve in the outlet line to
provide protection against impermissibly high
pressure.
• We recommend the installation of a pulsation
damper downstream the pump:
– for pipe installations.
– for hose installations where the pump is
operated with ≥75 % of its dosing capacity.
Install the control cube correctly to ensure
the enclosure class (IP65 / Nema 4X) and
shock protection.

7.1.1 Capacity adjusting knob
The capacity adjusting knob is used to set the
capacity in percent of the maximum dosing flow of
the pump. Due to the logarithmic increase of the
percent values, even small dosing capacities can be
set accurately.
7.1.2 LEDs (DDE-B)
The LEDs indicate the following operating statuses
and faults:
●= LED on
❍= LED flashing
empty table cell = LED off
* For some alarms the pump tries to restart
periodically. Observe section 9. Faults.

7.1.3 Keys and LEDs (DDE-AR)
When pressing and holding down the [100%] key, the
pump doses at 100 % for a certain time. The [100%]
key can be used e.g. for deaeration.
The [Operation mode] key is used to change the
operation mode. See section 7.2.4 Changing the
operation mode.
The operation mode LEDs indicate the active
operation mode. Only one operation mode can be
active at a time. Together with the status LEDs, the
operation mode LEDs indicate the following statuses
and faults:
●= LED on
❍= LED flashing
empty table cell = LED off
* For some alarms the pump tries to restart
periodically. Observe section 9. Faults.
7.2 Operation modes
Following operation modes are available:
•Manual, see section 7.2.1 Manual
•Pulse (DDE-AR), see section 7.2.2 Pulse
•Analog (DDE-AR), see section 7.2.3 Analog
7.2.1 Manual
In this operation mode, the pump doses constantly
the dosing quantity set by the adjusting knob.
The setting range depends on the pump type:
7.2.2 Pulse
Applies to DDE-AR control variant.
In this operation mode, the pump doses the set
dosing volume for each incoming (potential-free)
pulse, e.g. from a water meter. The pump
automatically calculates the optimum stroke
frequency for dosing the set volume per pulse.
The calculation is based on:
• the frequency of external pulses
• the set stroke volume in percent.
The dosing quantity per pulse is set to a value
between 0.125 % and 100 % of the stroke volume
using the adjusting knob.
The setting range depends on the pump type:
The frequency of incoming pulses is multiplied by the
set dosing volume. If the pump receives more pulses
than it can process at the maximum dosing flow, it
runs at the maximum stroke frequency in continuous
operation. Excess pulses will be ignored.

7.2.3 Analog
Applies to DDE-AR control variant.
In this operation mode, the pump doses according to
the external analog signal. The dosing volume is
proportional to the signal input value in mA. The
input signal must be 4-20 mA.
The maximum dosing volume can be changed via
the capacity adjusting knob.
Example:
7.2.4 Changing the operation mode
Applies to DDE-AR control variant.
1. Set adjusting knob to 0 %.
2. Connect power supply. See section 5.3 Electrical
connection.
3. Hold down the [Operation mode] key until the
next operation mode is activated.
– The operation mode LED indicates the active
operation mode.
– Repeat until the desired operation mode is
active.
7.3 Inputs/outputs
Applies to DDE-AR control variant.
7.3.1 External stop
The pump can be stopped via an external
contact, e.g. from a control room.
When activating the external stop signal, the pump
switches to operating state "Standby". The active
operation mode LED flashes green and the red
external stop LED is on.
The contact type can be changed. See section
7.3.4 Change settings.
7.3.2 Empty and low-level signals
In order to monitor the filling level in the tank, a
dual-level sensor can be connected to the pump.
The pump responds to the signals as follows:
The contact type can be changed. See section
7.3.4 Change settings.
