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).

This was the best
Size: 1 Panel
This divider is great for creating a little privacy or separating a small area without taking up much space. The fabric is thick enough to block visual clutter, and the frame is lightweight but stable once it’s opened. It folds flat for storage, which is convenient if you only need it occasionally. Assembly was straightforward, and it was the perfect size. It’s a practical piece for apartments, studios, or home offices where you want a quick, temporary partition.

Good privacy screen
Size: 1 Panel, Size: 1 Panel
This is a good privacy screen that's easy to assemble and looks nice. Be a little careful moving it, as the corners can twist. It's sturdy once in place, and the thick material is completely opaque. If the folds bother you, you might want to iron it, but I'm happy with it as is.

Lightweight divider that works well for video call backgrounds
Size: 1 Panel
This divider works fine for what it is, but it’s definitely on the lightweight side. Setup was very easy and only took a few minutes. The frame is fairly light, so it’s easy to move around or reposition if needed. That said, the tradeoff is that it’s not especially sturdy. It stands fine on its own but I wouldn’t expect it to handle much bumping or movement. I mainly bought it to use as a background for Zoom calls when I’m working from my den, and for that purpose it works great. The fabric panel blocks the room behind me and gives a cleaner background on camera. It’s not huge though. To keep the camera from seeing around it, I have to position it directly behind my chair. If you’re expecting it to divide a large room or create a big privacy barrier, it may feel a bit small. Overall, it does the job and works well for temporary setups or video call backgrounds, but the lightweight frame keeps it from feeling like a premium divider. The product description and photos are accurate.

Sent Wrong Pieces
Size: 1 Panel, Size: 1 Panel
I really, really wanted to like this - and, in theory, I really, really should have! The instructions were easy to follow and assembly took about five minutes. The assembled screen is lightweight and easy to move. It was a great size and exactly what I was looking for except....I wasn't sent the correct pieces. Instead of receiving 4 elbow pieces and 4 feet, I received 2 elbow pieces and 8 feet - meaning that the bottom part of the fabric just hangs there and, overall, the divider is extremely unstable because there is no horizontal support on the bottom. Thankfully, there are Velcro tabs on the side of the fabric so I can use it if I don't plan to move it even 1 cm, but otherwise, what I received is not usable for what I needed it for. Additionally, the fabric is made of polyester and catches animal hair very easily. Had I received the correct pieces, this would be a good buy for the money. Unfortunately, overall, I'm disappointed.

Works great, keeps the light out of my eyes and easy to put together
Size: 1 Panel, Size: 1 Panel
I got this room divider in and it works great. It’s really easy to put together you don’t even need tools. I really like that it’s not see through, it’s not a black out curtain but it keeps light out pretty good. I absolutely hate my bedroom layout there’s no bathroom door. My girlfriend and I have different work schedules so I’m trying to sleep while she’s getting ready for work and the light shines right in my eyes. This divider keeps the light out of my eyes and that’s exactly what I was hunting for. I also like that you can adjust the length. I took one of the bars out to make it a little shorter and it worked great. I would recommend this room divider.
