Whether in water treatment, industrial manufacturing, or agriculture, these pumps help maintain optimal conditions and improve overall process outcomes.

Digital Dosing
The SMART Digital S generation DDA, DDC and DDE with powerful variable-speed stepper motor brings state-of-the-arttechnology to perfection. Combined expert knowledge and 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 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).

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 by, for example, 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, such as 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 due to the universal chemical resistance of the full-PTFE diaphragm
• reduced energy consumption due to the state-of-the-art drive technology.

Three application-oriented type ranges
DDA is a high-end pump range for extended flow and pressure ranges with sensor-based FlowControl and measurement functions for challenging industrial applications such as the following:
• process water
• food and beverage
• ultrafiltration and reverse osmosis
• pulp and paper
• boiler feed water
• CIP (Cleaning-In-Place).

DDC is a user-friendly pump range with standard inputs and outputs for common applications like the following:
• drinking water
• waste water
• swimming pool water
• cooling tower
• chemical industry.

DDE is a low-budget pump range with basic functions including manual operation or control via PLC for OEM applications, for example:
• car wash
• irrigation.

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. 

The advantages are as follows:
• The pump always operates at full stroke length, irrespective of the capacity set, which ensures optimum accuracy, priming and suction.
• A capacity range of up to 1:3000 (turn-down ratio) results in less variants and spare parts
• Smooth and continuous dosing ensures an optimum mixing ratio at the injection point without static mixers.
• There is a 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.
• Dosing of high-viscosity and degassing liquids (SlowMode) is easier.
