Digital DosingTM
The SMART Digital XL generation DDA and DDE with powerful PMS (Permanent Magnet Synchronous) motor brings state-of-the-art technology to perfection. Combined expert knowledge and patented solutions set future standards.
Traditional technologies, such as stroke length or stroke frequency adjustment with asynchronous motor, become a thing of the past.

Unique flexibility with only a few variants
The included mounting plate makes the pump more flexible. Service and pump exchange is easy and fast: just dismantle the pump from the mounting plate by removing two screws.
The control cube of the pump can be lifted and turned into three different positions: front, left or right

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 of the DDA pump, 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 up to 28 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 by air bubbles for example, 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 XL DDA 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 double full-PTFE diaphragm
• reduced energy consumption due to state-of-the-art drive technology.

Two application-oriented type ranges
DDA is the high-end pump range for extended flow and pressure ranges with sensor-based FlowControl and measurement functions for challenging industrial applications, such as:
• drinking water treatment
• wastewater treatment
• boiler water treatment
• cooling water treatment
• process water treatment
• chemical industry
• ultrafiltration process and reverse osmosis
• food and beverage industry
• paper and pulp industry.

DDE is the economical pump range with basic functions including manual operation or control via PLC for OEM applications, such as:
• drinking water treatment
• wastewater treatment
• boiler water treatment
• cooling water treatment
• process water treatment
• chemical industry
• ultrafiltration process and reverse osmosis
• food and beverage industry
• paper and pulp industry
• irrigation
• swimming pool water.

Functional description
The electronically controlled PMS (Permanent Magnet Synchronous) motor of the DDA 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 dosing 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, which ensures optimum accuracy, priming and suction.
• A capacity range of 1:800 (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.
• Pressure peaks are significantly reduced, preventing mechanical stress on wearing parts, such as the diaphragm, tubes, connections, resulting in extended maintenance intervals.
• The installation is less affected by long inlet and outlet lines.
• Dosing of high-viscosity and degassing liquids (SlowMode) is easier.
