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.

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).

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.
