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).

Shocked
Color: White, Size: Queen (Pack of 2)
I'm really bougie when it comes to pillows. I've never spent less than $50 on a pillow. I'm a side sleeper and like firm support, but also want something soft. I almost ordered the really pricey pillows on Amazon, but was turned off by all the odor complaints. I needed something quick to at least hold me over until I could get exactly what I want, so I took a shot with this pillow with the plan of it being a temporary fix. However, this pillow turned out to be exactly what I was looking for. The first time I laid on it I was skeptical. It had support, but felt like it may have been too soft. It took a bit to get accustomed to, but by the second night I knew this is the pillow. No chemical odors, it's quality at a low cost. I figured this pillow would've been quickly replaced and put into the leg pillow rotation, but it is shockingly a really great pillow. It is not lumpy, stays way cooler than standard or shredded memory foam and is comfy. Hopefully it holds up for a long time. I've paid triple what these 2 pillows cost for a single pillow that isn't as good.

Favorite pillows
Color: White, Size: Queen (Pack of 2)
These pillows are amazing! They are huge and plush but you can change that if you prefer. I really like that the outside cover can be washed and is also filled. It held up great in the washer and dryer. I just followed the directions on the tag. Great price for the quality and look very nice and fluffed on the bed.

Good option
Color: White, Size: Body(Pack of 1)
I’ve been using the ACCURATEX Full Body Pillow for Adults – Hybrid Shredded Memory Foam for a few weeks now, and overall I’m really happy with it. The blend of shredded memory foam gives it a firm, supportive feel, but what I love most is that you can adjust the filling to get the exact firmness you want. Whether you prefer something more structured or slightly softer, it’s easy to customize by adding or removing foam. Comfort-wise, it’s definitely a step up from standard body pillows. It keeps its shape throughout the night and offers great support for side sleeping. That said, it is a bit firmer out of the box than I expected, which is why I’m giving it 4 stars instead of 5. If you’re looking for a body pillow that won’t go flat and lets you tweak the feel to your liking, this one is a solid choice.

Favorite pillow!!
Color: White, Size: Body(Pack of 1)
I honestly wasn’t expecting to love this pillow as much as I do. Buying pillows online always feels risky because you can’t actually feel them beforehand, but this ended up being one of the best blind buys I’ve made on Amazon. The quality is genuinely shocking for the price. It feels way more expensive than it is. It’s insanely comfortable, supportive without feeling stiff, and just has that “perfect” cozy feel. I have neck problems, so I’m really picky about pillows, and this one somehow manages to be the perfect balance. It’s supportive without being stiff or overstuffed, but also not too flat where your neck feels unsupported. It has that perfect “sink in but still supportive” feel that’s hard to find. I loved the body pillow version so much that less than a week later I’m already ordering the regular pillow version too. Easily 5 stars from me!!

Probably going to replace all the pillows in the house with these
Color: White, Size: King (Pack of 2)
These pillows are just about perfect. They have to be the best pillow for the money out there at least. I didn't even know that this kind of pillow existed but was asking Google Gemini what kind of pillow would best suit my list of needs and this is what we came up with. - High loft for comfortable side sleeping, but can be reduced by removing foam to be less high - Gives initially, but stays at that new same thickness throughout the night b/c it's memory foam chunks - Doesn't feel lumpy because it has the 1cm outer pillow layer that covers the memory foam pieces I'm 6/3" 210lbs and after a couple nights of adjusting I found that removing about 1 gallon ziploc of foam chunks from each pillow was about perfect. I saved the foam in ziplocs in case I change my mind. They come REALLY loaded at first so should fit literally anyone with some adjusting. It was definitely too big the first two nights until I got it just right.
