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 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.

  • 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:

  • Auto deaeration during pump standby to avoid stand-still due to air-locking.

Fantastic Fragrance Free Vitamin C
Really nice Vitamin C product. It goes on nicely without any off putting scent. I tried this one after trying another Vitamin C serum my dermatologist recommended, but the consistency and smell of the other one makes this one a dream to use in comparison. Instead of a dropper, it is dispersed using a pump. The consistency is thin, but not watery. It does not leave my skin feeling sticky. I love not having it drip all over my face. Leaves a nice glow without being shiny. Time will tell how effective it is at fading brown spots, but as with the other Good Molecules products, this is a great product for a great price.

Great buy and a have to try
This is a very nice vitamin C serum/cream. It spreads nicely, so you do need a lot. A little really does go a long way. I wash my face, apply serums, and then apply this on top before my moisturizer. It doesn't pill up at all for me. In fact, it layers really well. It's dry time is fairly quick, and it's a GREAT value for your money. It's also not oily at all. I've been using it for over a week now and I can tell my complexion is brighter and the one dark spots are s bit lighter. I'd say it's pretty effective.

Nice creamy texture
I like this serum because it's more like a cream rather than the oily types of serums. It goes on nice and softens my skin. I'll know more over time when I use it longer.

Brightened My Skin and Feels Lightweight
I’ve been using this Vitamin C serum consistently and I really like how lightweight and gentle it feels on my skin. It absorbs quickly without leaving a sticky feeling and layers well with my moisturizer. After a few weeks of use, my skin started looking brighter and more even, especially around dark spots and dull areas. I also appreciate that it did not irritate my skin or cause breakouts. The packaging is simple and the product feels high quality for the price. A great addition to my skincare routine!
