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).

These work great for home office.
Color: Gray, Size: 24" wide, 66" Tall
I was looking for something to block background for a home office, so I wouldn't have to use the distracting background filters. These work great and give my backdrop a more professional appearance. They are very easy to install. The box arrived with a few shipping holes, but packaging was sufficient to avoid any product damage.

great purchase
Size: 48" X 10', Color: Grey, Number of Items: 1
I bought this AmazingSpark soundproof room divider panel because I work from home and needed a way to separate my workspace from the rest of the room — and honestly, it’s been such a great solution. The 48" x 10' size is big enough to create a true sense of separation, and the foldable design makes it easy to move around or tuck away when I’m done working. I use it mostly in my home office, but I’ve also tried it in our guest room when I needed a little quiet space to focus, and it worked perfectly. The first thing I noticed was how sturdy and well-made it feels. The fabric panels are thick and tightly stretched, and the frame has a solid feel without being too heavy to move. I really like that it comes with straps and a stand, so it stays put even if you have pets or kids running around. The neutral grey color blends nicely into any space — it looks sleek and professional but still warm enough to fit in a home environment. As for soundproofing, it’s not total silence (no panel really is), but it makes a big difference. It does a great job of dampening echo and blocking background noise, especially when I’m on calls or recording audio. It’s been a huge improvement compared to the open room I had before. I even noticed my space feels cozier and less “echoey” during Zoom meetings. Setting it up was straightforward — it took me about 15 minutes by myself. The panels fold like an accordion, so you can easily adjust how much space you want to block off, and it’s easy to collapse and store when you don’t need it. The handles and lightweight construction make moving it from one room to another surprisingly easy for its size. One little thing to note: if you have hardwood floors, it helps to put something soft underneath the stand to prevent sliding when you bump it. It’s not a dealbreaker, but it made a small difference for me. Other than that, it’s super stable and does exactly what I needed. What I really appreciate is that it’s multi-functional — I use it as a sound barrier for work, but we’ve also pulled it out to create a bit of privacy when guests stay over or when I just want to section off a reading nook. It instantly changes the feel of a space. Overall, this divider has been practical, stylish, and surprisingly effective. It gives me more control over noise and privacy, looks great, and folds up easily when not in use. If you work or study from home and need a quick way to carve out a quiet corner, this thing is absolutely worth it.

Light enough for one person to move, sturdy and so versatile
Size: 48" X 10', Color: Grey, Number of Items: 1
The AmazingSpark Soundproof room divider panel has been a fantastic addition to my classroom. Its sound-absorbing design noticeably reduces noise, which makes small group instruction, testing sessions, and independent work time much more manageable. The panel is lightweight yet sturdy. The included stand and straps keep it securely in place. I appreciate how easily it folds - setup and storage take only a minute, which is perfect for transitioning from one activity to another. The grey color looks clean and professional, and I can use push-pins to hang displays on the board. The divider delivers exactly what teachers need: privacy, noise reduction, flexibility, and durability. The noise reduction feature has been beneficial in my classroom when students are recording projects. While the class is working quietly on other activities, a small group can move to the opposite side of the panel and record their audio files. When we listened to the files, we could not hear any background noises, with the exception of the noises they wanted in their recording. This panel is made to last, and I would recommend it for anyone who is looking for an acoustic panel that is flexible. The panel is extremely versatile, and because of that, I think it is a good value for the money. Noise reduction, privacy screen, or to section off one area from the rest of the room are just a few of the uses of this product.
