grundfos Water Treatment SMART Digital Modular, simple, intelligent SMART Digital dosing pumps from 0.0025 to 30 l/h Digital Dosing Advanced process reliability The SMART Digital generation DDA, DDC and DDE with powerful variable-speed stepper motor brings state-of-theart technology to perfection. An intelligent drive and microprocessor control ensure that dosing is performed precisely and with low pulsation, even if the pump is dosing high-viscosity or degassing liquids. Malfunctions are detected quickly by the maintenance-free FlowControl system and then displayed in the alarm menu. Combined expert knowledge and the patented solutions set future standards. Traditional technologies such as stroke length / 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. Service and pump exchange can now be done easily and fast by just clicking the pump in and out of the mounting plate. The control cube on the DDA and DDC pump can be easily turned into three different positions. 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 DDA, DDC and DDE pumps contribute to low life cycle costs: 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. • No underdosing or overdosing due to high dosing accuracy and FlowControl Precise and easy setting • Reduced energy consumption thanks to state-of the-art drive technology. 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 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. Thanks to a variety of operation modes, signal inputs and outputs, the pump can easily be integrated into every process. • Longer maintenance intervals thanks to the universal chemical resistance of the full-PTFE diaphragm
