Digital DosingTM
The SMART Digital S generation DDA, DDC and DDE
with powerful variable-speed stepper motor brings
state-of-the-art technology to perfection.
Combined expert knowledge and the patented
solutions set future standards. Traditional technologies
such as stroke length or stroke frequency adjustment
with synchronous motor or solenoid drive become a
thing of the past.
Unique flexibility with only a few variants
The included click-stop mounting plate makes the
pump more flexible. Three different positions are
possible without using any additional accessories,
such as wall brackets. Service and pump exchange
can now be done easily and fast just by clicking the
pump in and out of the mounting plate.
The control cube on the DDA and DDC pump can be
lifted and turned easily into three different positions:
front, left or right.
Fig. 3 Modularity of the control cube
A turn-down ratio of up to 1:3000, a wide supply
voltage range (100-240 V; 50/60 Hz), combined
connection sets and other features reduce the models
and variants to a minimum.
Precise and easy setting / usability and interaction
The operator can easily install the pump and set it to
discharge exactly the quantity of dosing liquid required
for the application. In the display, the setting of the
pump is read out directly, the flow is shown in ml/h, l/h,
or gph.
The click wheel (turn-and-push knob) and the
graphical LC display with plain-text menu in more than
25 languages make commissioning and operation
intuitive. As the LCD is backlit in different colours, the
pump status can be seen from a distance (traffic-light
concept).
Fig. 4 Display DDA, DDC
Thanks to a variety of operation modes, signal inputs
and outputs, the pump can easily be integrated into
every process.
Advanced process reliability
An intelligent drive and microprocessor control
ensures that dosing is performed precisely and with
low pulsation, even if the pump is dosing high-viscosity
or degassing liquids. Malfunctions, caused e.g. by air
bubbles, are detected quickly by the maintenance-free
FlowControl system and then displayed in the alarm
menu.
The AutoFlowAdapt function automatically adjusts the
pump according to the process conditions, e.g. varying
backpressure. The integrated flow measurement
makes additional monitoring and control equipment
redundant.
Designed to save costs
In general, the investment for a dosing pump
installation is low compared to its life cycle costs
including the cost of the chemicals. The following
features make the SMART Digital S DDA, DDC and
DDE pumps contribute to low life cycle costs:
• No underdosing or overdosing due to high dosing
accuracy and FlowControl
• Longer maintenance intervals thanks to the
universal chemical resistance of the full-PTFE
diaphragm
• Reduced energy consumption thanks to
state-of-the-art drive technology.

Functional description
The electronically controlled variable-speed motor
(stepper motor) of the DDA, DDC and DDE pumps
provides optimum control of the stroke speed.
The duration of each discharge stroke varies
according to the capacity set, resulting in optimum
discharge flow in any operating situation, while the
duration of each suction stroke is constant (see figure
below).
The advantages are as follows:
• The pump always operates at full stroke length,
irrespective of the capacity set; this ensures
optimum accuracy, priming and suction.
• A capacity range of up to 1:3000 (turn-down ratio)
reduces variants and spare parts.
• Smooth and continuous dosing ensuring an
optimum mixing ratio at the injection point without
needing static mixers.
• Significant reduction of pressure peaks, preventing
mechanical stress on wearing parts such as
diaphragm, tubes, connections, resulting in
extended maintenance intervals.
• The installation is less affected by long suction and
discharge lines.
• Easier dosing of high-viscosity and degassing
liquids (SlowMode).
The optimum dosing control shown below takes place
in any operation mode.

Operation modes
Manual control
The pump ensures constant dosing according to
the quantity set in l/h or ml/h or gph by means of the
click wheel. The pump automatically changes between
the measuring units.
Setting range
* When the SlowMode function is enabled the max. flow is reduced
(see page 13)
Pulse control
The pump doses in proportion to an external
potential-free pulse signal, for example from a water
meter. There is no direct relation between pulses and
dosing strokes. The pump automatically calculates its
optimal speed to ensure that the required quantity is
dosed for each incoming pulse.
Applies to DDA and DDC
The quantity to be dosed is set in ml/pulse. The pump
adjusts its speed according to two factors:
• the frequency of external pulses
• the set quantity per pulse.
Setting range
The frequency of external pulses is multiplied by the
set quantity. If the product exceeds the maximum flow
of the pump, a maximum of 65,000 pulses can be
stored for later processing with the Memory pulse
function, when activated.
Applies to DDE-PR, DDE-P control variant
The dosing quantity per pulse is adjusted with the
adjustment knob according to the scale from 0.1 to
100 % of the stroke volume. The pump adjusts its
speed according to two factors:

Pulse-based batch control
Applies to DDA
The set quantity is dosed in batches within the set
dosing time (t1). A batch is dosed every time the pump
receives an external pulse. If the pump receives new
pulses before a batch is completed, these pulses will
be ignored. In the event of interrupts such as external
stop or alarm, incoming pulses will also be ignored.
After ending of the interrupts, a new batch will be
dosed with the next incoming pulse.
Fig. 12 Pulse-based batch control
Setting range
* Due to the digital motor control, down to 1/8 of the dosing volume
can be dosed.
Dosing timer cycle
Applies to DDA
After a start delay (t2) the set batch volume is
repeatedly dosed in the set cycle time (t3). The dosing
time (t1) can be adjusted. Batch dosing is stopped
during any interrupt, e.g. power supply failure or
external stop while the time continues running in the
background (real-time clock). After ending of the
interrupt, batch dosing proceeds according to the
current status in the timeline.
Fig. 13 Dosing timer cycle
Setting range
The batch volume setting range corresponds to the
pulse-based batch control setting range.
Dosing timer week
Applies to DDA
The integrated real-time clock features also batch
dosing based on a weekly period. There is a maximum
of 16 procedures per week. Each dosing procedure
consists of:
• Batch volume
• Dosing time
• Start time
• 1 to 7 weekdays (Monday to Sunday).
In case several procedures are overlapping, the
procedure with the highest flow rate has the highest
priority. Batch dosing is stopped during any interrupt,
e.g. power supply failure or external stop, while the
time continues running in the background (real-time
clock). After ending of the interrupt, batch dosing
proceeds according to the current status in the
timeline.

Functions
SlowMode
Applies to DDA, DDC
When the SlowMode function (anti-cavitation) is
selected, the pump extends and smooths its suction
stroke. This results in a softer suction stroke.
The SlowMode function is used in these situations:
• when pumping high-viscosity liquids
• when pumping degassing liquids
• when the suction line is long
• when the suction lift is high.
Depending on the application, the motor speed during
the suction stroke can be reduced individually to
approximately 50 % or 25 % of the normal motor
speed.
The maximum pump capacity is reduced accordingly.
See pages 25 and 26 for further details.
Auto deaeration
Applies to DDA
The auto deaeration function avoids breakdown of the
dosing process due to air-locking, when dosing
degassing liquids such as sodium hypochlorite.
During long dosing breaks, e.g. at the weekend or
overnight, air-bubbles can form in the suction line and
get into the dosing head. If too much air is in the
dosing head, and the dosing process is started again,
no liquid will be dosed (air-lock). Software-controlled
diaphragm movements at regular intervals encourage
the air bubbles to rise and finally to be displaced out of
the dosing head.
These movements are executed
• when the pump is not stopped and
• during dosing breaks (e.g. external stop or no
incoming pulses).
Calibration
Applies to DDA and DDC
The pump is calibrated in the factory at the nominal
pressure of the respective pump type (see maximum
pressure Technical data page 25, 26). After start-up,
the dosing pump can be calibrated for the actual
installation to ensure that the displayed value (ml, l or
gph) is correct. A calibration program in the setup
menu facilitates this process. The AutoFlowAdapt
function keeps the dosing precision (DDA-FCM control
variant), even if the backpressure changes.
For the description of the AutoFlowAdapt function, see
page 18.
External stop
Applies to DDA, DDC, DDE-PR, DDE-P
With the external stop function, the pump can be
stopped from a remote place via an external contact. It
is not recommended to switch on and off the power
supply as it was usual when working with a
conventional dosing pump. When working with
microprocessor-controlled digital dosing pumps, the
external stop signal has to be used, in order to keep
the optimal dosing precision and to prevent damages
to the electronics.
When activating the external stop signal, the pump
changes from running to standby . The operation
display shows an activated external stop .
The signal input can be set to normally open (default)
or normally closed contact.
Counters

Service display
Applies to DDA, DDC
Due to the optimised construction and the smooth
digital dosing principle, the service periods are more
than twice as long, if compared to conventional pumps.
However, the wear parts have to be exchanged in
regular intervals in order to keep the dosing precision
and the process reliability at a high level. The service
display in the pump shows when service of the wear
parts is required. The displayed service kit product
number makes service more convenient. The following
information is displayed in the Info display:
The following service messages appear, depending on
what happens first:
* Applies to DDA only
In case of difficult liquids the service intervals can be
shorter and service has to be performed earlier.
Level control
Applies to DDA, DDC, DDE-PR and DDE-P
The pump can be connected to a dual level control unit
for monitoring of the chemical level in the tank. The
pump can react to two level signals:

FlowControl
Applies to DDA-FC/FCM
Fig. 17 DDA FlowControl
The pump monitors the dosing process of liquids when
the FlowControl function is activated. Although the
pump is still operating, some influences such as air
bubbles may cause reduced flow rates or even stop
the dosing process. For optimal process safety and
reliability, the activated FlowControl function
immediately detects and displays the following
malfunctions:
• Overpressure
• Discharge line burst
• Air bubbles in the dosing head
• Cavitation at the suction side
• Suction valve leakage
• Discharge valve leakage.
The unique FlowControl is based on an intelligent and
maintenance-free sensor integrated in the dosing
head. During the dosing process, the sensor measures
the actual pressure and sends the measured value to
the microprocessor in the pump. An internal indicator
diagram is generated combining the actual pressure
value with the diaphragm position (stroke length).
With it, the dosing process is monitored, as the
different malfunctions can immediately be detected
due to their specific deviations in the curve.
Compressible air bubbles, for instance, will reduce the
discharge phase and the stroke volume (see fig. 18).
The sensitivity and the delay of the FlowControl
function can be adjusted individually.
FlowControl requires a minimum backpressure of
2 bar. Grundfos recommend an additional
spring-loaded valve (approx. 3 bar) on the discharge
side for dosing low capacities (< 1 l/h) (please see
page 46).

Pressure monitoring
Applies to DDA-FC/FCM
The integrated pressure sensor measures the actual
pressure of the system, which is shown in the display.
A maximum pressure can be set. If the pressure in the
system exceeds the set maximum (e.g. caused by a
closed valve), the pressure monitoring function stops
the dosing process immediately. As soon as the
backpressure falls below the set maximum, the dosing
process is continued. In case the pressure drops below
the minimum limit (e.g. caused by a burst discharge
line) the pump stops and major chemical spills are
prevented.
Pressure setting range
* Can be either set as a warning (pump keeps running) or as an
alarm (pump stops)
** The adjustable max. pressure is equivalent to the max. operating
pressure plus 1 bar
Flow measurement
Applies to DDA-FCM
The pump can precisely measure and display the
actual dosing flow. Via the analog 0/4-20 mA output,
the actual flow signal can easily be integrated in any
process control system, without needing any additional
measurement equipment.
The Flow measurement function is based on an
indicator diagram as described in FlowControl
(page 16). Accumulating the length of each discharge
stroke phase and multiplying it with the stroke
frequency results in the displayed actual flow.
Any malfunctions, such as air bubbles or lower
backpressure, will result in a reduced or increased
actual flow rate. When the AutoFlowAdapt function
(page 18) is activated, the pump compensates these
influences by correcting the stroke speed.
AutoFlowAdapt
Applies to DDA-FCM
When activating the AutoFlowAdapt function even
environmental changes will be compensated, so that
the required target flow rate will be achieved.
The integrated AutoFlowAdapt makes additional
monitoring and control devices redundant.
The AutoFlowAdapt function is based on:
• FlowControl: malfunctions are detected
• Pressure monitoring: system pressure changes are
detected
• Flow measurement: deviations in the target flow are
detected.
Examples:
• FlowControl detects air bubbles in the system.
Due to a special motor drive strategy and a certain
speed increase, the pump will try to keep the flow
rate constant. This is especially important when
dosing degassing liquids.
• In general, increasing system pressure reduces the
stroke volume whereas falling system pressure
increases the stroke volume. The AutoFlowAdapt
function compensates this by automatically and
continuously adapting the motor speed.
Despite fluctuating system pressure, dosing
accuracy is maintained.
