The SMART Digital DDA-C is a compact positive-displacement diaphragm dosing pump with variable-speed drive (stepper motor) and intelligent control electronics with minimum energy consumption. The SMART Digital Dosing series operates at full stroke length to ensure optimum accuracy, priming and suction, even for high-viscosity or degassing liquids. Depending on the set capacity, the duration of the discharge stroke varies, ensuring an optimal, uniform and continuous discharge flow. The click-stop mounting plate allows installation in three different positions without using any additional accessories. The control cube can be easily turned to the front, left or right position. The click wheel and the multi-coloured backlit graphic plain-text LC display enable intuitive commissioning and operation. The control elements are protected by a transparent cover. The DDA-C has built-in connectivity that allows easy setup and tracking via the Grundfos GO app as well as easy integration into a Modbus RTU or TCP bus system. The sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head and displays them in plain text in the alarm menu. FCM measures the actual pressure and flow rate and eliminates the need for additional monitoring and control devices (accuracy of ± 1.5 % of the set value in a trouble-free process). The measured pressure and flow are displayed and can be integrated into the process control system, e.g. SCADA. In addition, the AutoFlowAdapt function automatically adjusts the pump speed to the process conditions to maintain the target flow even with fluctuating back pressure or air bubble formation (degassing drive strategy). The dosing head includes the following parts:

  • A durable and chemically resistant full PTFE diaphragm,
  • Double ball valves for maximum dosing accuracy,
  • A deaeration valve for easy start-up,
  • A pressure sensor.

Operation modes and functions:

  • Manual dosing in ml/h, I/h or gph.
  • Pulse control in ml/pulse (incl. memory function).
  • Analog control, 0/4-20 mA (scalable).
  • Pulse-based batch function in ml, l or gal.
  • Timer-based batch function (dosing timer cycle or week).
  • Fieldbus control (integrated Modbus RTU and TCP; Profibus DP, Profinet and Ethernet IP via CIM/CIU models).
  • Cloud control and monitoring (Smart Digital Chempairing Suite; Grundfos Connect).

Other features:

  • The sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head.
  • Measurement of actual pressure and flow.
  • AutoFlowAdapt automatically adjusts the pump speed to the process conditions (what you set is what you get).
  • Degassing drive strategy in case of air bubbles detected in the dosing head and Auto Deaeration during pump standby avoids stand-still due to air-locking.
  • ConditionCheck analyses the pump and the system where the pump is installed.
  • Two SlowMode steps (anti-cavitation), 50 % and 25 % maximum flow, e.g. for high-viscosity or degassing liquids.
  • Max. Capacity to limit the capacity of the pump to a set maximum.
  • Service information display to show when service and which wear-part order numbers are required.
  • Two-step key lock function to protect the pump against unauthorised access.
  • Multi-parameter dashboard function to provide further information on up to 4 parameters.
  • Counter for total dosed volume (resettable), operating hours, etc.
  • Save, copy and load customised settings as well as reload factory settings.

Signal inputs/outputs:

  • Input for pulse, analog 0/4-20mA, external stop.
  • Input for low-level and empty-tank signal.
  • Two potential-free output relays for max. 30 V AC/DC (configurable, e.g. alarm, stroke signal, pump dosing, timer etc.)
  • Output analog 0/4-20mA.
  • Fieldbus control (Integrated Modbus RTU and TCP; Profibus DP, Profinet and Ethernet IP via CIM/CIU models).
  • Cloud control and monitoring (Smart Digital Chempairing Suite; Grundfos Connect).

Light and easy to move around! Still sturdy and tall like I wanted.
Color: Grey, Size: 2 Large Panels
Easily put together, work excellently for a room divider and taller than I am at 5'9" so that makes the privacy really great for our purposes. The feet turn and so you can get them out of a pathway as needed, the middle one that has two posts in it does not move but the end ones do. Very LIGHT so not hard to move around. Fabric is not see through. We have a lamp on one side and you can see the light through it but that is not an issue for us. The price is right!! most cubicle kinds of walls are so, so, so much money. With these being light and still give privacy the price was great. If you want them for sound, this is not the product for you but really most cubicle calls are not going to give you privacy other than visually anyway and these do that well. The size was accurate and so fit exactly how I needed them to and that was an important point for me. I used both of them in L shapes for my room and the size was right on.

Almost perfect
Color: Black, Size: 2 Large Panels, Color: Black, Size: 2 Large Panels
The cloth material is sturdy and fits well on the design. Both sides are black and you can't tell a difference between each side. It's extremely light weight and easily movable. We got a double and a single and the single is used as a sliding door. It's definitely not the MOST stable thing but overall it's pretty stable, probably won't work GREAT on carpet. It's not see through at all, which is great, the only downfall is the gap between the two sides. We are using a blanket to cover the gap. It's not 6 foot tall, but you can adjust the feet on it to be taller. Overall it's a great product for the price and can easily be moved out of they way.

A decent buy
Color: Black, Size: 1 Large Panel
Easy to assemble, good quality fabric, the two horizontal "feet" are supposed to be stabilized by a knob/screw but its always looosening up with even the slightest move, so the only unfortunate thig is that it requires constant turning to tighten it if you adjust its location even a teensy bit. I used it as a backdrop to hold a design of balloons, then since the party I use it as a "semi" partition in a bedroom. Good value for the money since it can be used over and over.

Inexpensive Solution For Privacy
Color: Grey, Size: 2 Large Panels, Color: Grey, Size: 2 Large Panels
This worked for my needs to get privacy on a second-floor patio that faced neighbors about 16 feet away, and was almost exactly the width and height I need, and was looking for. As the patio was about 12 feet in width. The fabric is thin, but not see-through, and works well enough for my specific privacy needs. It wasn't that sturdy, even with the three legs, the top would kind of bend a bit from the weight of the thing, but I knew this from previous comments on reviews, and opted to use C-clamps and some screws to tighten it to the wall so that isn't an issue since I was outside and had walls to be able to screw into. You may have to try something different if using inside. I gave four stars instead of five as the instructions past Step 3 really don't make much sense for Steps 4 and 5 where the two are connected and when legs are put on, but I was able to work through it eventually. They really need to break down the steps for installing the legs with better illustrations. Also, highly recommend having two people work on it or at least having a second person on standby for certain steps just due to the size of them once they are together or for connecting the dividers together in the end.

Very sturdy & nice looking! Impressive & functional
Color: Black, Size: 2 Large Panels, Color: Black, Size: 2 Large Panels
I needed to divide our living room room in half and create a work room but didn’t want it to be visible so we decided to get this and use it in an L shape. It’s very simple and functional, but it does exactly what I need. I’m contemplating hanging a photograph from a ribbon just to add a little personality to the side that faces the living room room but honestly, it’s much more sturdy than I gave a credit for. I am a full-time reseller so I got foam from the hardware store and covered it in fabric as a background for taking pictures and I have a huge one that’s 6‘ x 3‘ plus another one that’s 4‘ x 4‘ both of which are hanging on the inside of this and it works great. I’m impressed!!
