Tried and tested Digital Dosing™ solution
Available since 2010, the Grundfos SMART Digital dosing pump range is known for its state of the art monitoring features that ensure dependable, safe, and economical dosing operations, and for its industry-leading accuracy.The range is available in two size categories: SMART Digital S (dosing flow up to 120 l/h, pressure up to 16 bar, turn-down ratio up to 1:3000)SMART Digital XL (dosing flow up to 200 l/h, pressure up to 10 bar, turn-down ratio up to 1:800)The SMART Digital S DDA, DDC, and DDE and the SMART Digital XL DDA and DDE are all based on tried and tested Digital Dosing™ technology from Grundfos. They offer powerful, variable-speed motors, a universal power supply, and a full-PTFE diaphragm that meets the most demanding requirements for chemical resistance and durability. The pumps open up a broad range of dosing applications.
The DDA model is the pump for complex and demanding applications where the focus is on maximum process reliability. In addition to an extended capacity range and a turn-down ratio of up to 1:3000, it boasts FlowControl, pressure monitoring, AutoFlowAdapt and integrated flow measurement. The package for industrial applications is rounded off by additional operating modes such as a week dosing timer and new functions such as auto deaeration.
The DDC impresses with features such as simple, intuitive click-wheel operation and a graphic LC display in more than 25 languages. What's more, all standard modes of operation and inputs/outputs such as analog control or output relay can be integrated into control systems. This pump is suitable for universal use thanks to highlights including the SlowMode (anti-cavitation) function for highly viscous media and the straightforward calibration mode.
The DDE is the cost-effective entry-level model with all the benefits of Digital Dosing such as a maximum turn-down ratio of 1:1000 and smooth, continuous dosing. This one model can replace a whole host of existing models with dosing rates ranging from 0.006 to 6 l/h. The rate is set using a logarithmic scale that runs from 0.1-100 %. The model's straightforward pulse control, external stop function and empty level signal are ideal for basic OEM applications.
Features and Benefits
Simplicity – simple handling and perfect overview and control even from the distance
- The system is extremely easy to use thanks to the new click wheel and straightforward, intuitive navigation via a graphic LC display in more than 25 languages. The required flow can be set directly on the display in ml/h, l/h or gph.
- The large LC display indicates the pump status by changing the back light color, allowing fast and easy control of the pump´s performance.
Modularity – flexible and suitable for any environment or situation
- The new pump family has a turn-down ratio of up to 1:3000 / 1:1000 significantly reducing the number of different models required.
- The models have a universal mounting plate for all popular mounting methods. The click function makes it quick and easy to remove the pump from the mounting plate if necessary.
- Maximum flexibility is ensured by a control cube that can be rotated, a wide range of adjustments and supply voltages (100-240V, 50/60 Hz), and a hydraulic connection kit.
- The optional E-box enables SMART Digital pumps to be integrated – and even retrofitted – in systems such as complex Profibus networks.
Flow Intelligence – highest process reliability
- The FlowControl system prevents unwanted stoppages, even with variable process parameters such as fluctuations in system pressure.
- The technology used in SMART Digital pumps provides an accurate diagnosis of the most common causes of faults that occur during dosing with diaphragm pumps. These faults are displayed in plain text in the alarm menu.
- What's more, the AutoFlowAdapt function ensures that the dosing process continues with the required flow, even when subject to external influences. When dosing outgassing media, for example, motor control is automatically adjusted as soon as air bubbles are detected so that they can escape out of the dosing head. Fluctuating system backpressures no longer impact on the required flow either – deviations are automatically corrected by the stepper motor's speed regulation mechanism.
- The integrated flow measurement function makes costly additional measuring equipment unnecessary. The current flow measurement is shown directly on the display and can also be integrated in the control room via the analog output or bus protocol if necessary.

To achieve optimum performance and operating condition it is very important that the Product/System is set up and adjusted correctly from the start. The knowledge from the Grundfos Service technician and the use of Grundfos specific service tools to adjust the performance of the pump guarantee that the customer can be sure that that the highest efficiency and proper operation is achieved. Commissioning of the pump is recommended for the following applications:
- If the pumps are controlled by a frequency converter .
- If the pump system is operating in large systems e.g. Building Management Systems.
- If the user wants to be trained in proper operation of the pump.
- If the pump must not be a missing link in an important production/application facility.
- Where the setup is crucial for proper life of the Grundfos product, e.g. water treatment applications, commissioning is not only recommended but it is required.
- Where safety is an issue e.g. disinfection system.
The commissioning is performed in a step by step procedure and the outcome will be a report of the settings of the pump.
Do not hesitate to contact your local Grundfos company to arrange commissioning of you new installed Grundfos product.
Recommended Spare Parts
Even though the Grundfos strategy is to supply the best pump solutions for our customers, long operation will result in wear and tear of some of the components in the construction in specific situations. If a short operating downtime is a demand or if the pump is installed in inaccessible areas where delivery of service parts may take a long time, it is recommended to have a small stock of recommended service parts.
Do not hesitate to contact your local Grundfos company to obtain information about recommended spare parts or service kits for your Grundfos product.
