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,

  • 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:

Very soft, not firm at all
This pillow is very floppy and not firm at all. It is quite large and I was surprised at the size. My dog has taken a liking to it and decided it's now her new dig bed, which is fine by me, because it's really too soft for my liking. If you like soft pillows then this is for you. If you require something with a bit more support then you won't enjoy this pillow.

Soft and supportive
I recently purchased the this pillow and I am happy with the quality and comfort it provides. Pillow is soft, plush, and supportive without being too firm. The down alternative fill offers the balance of fluffiness and structure, making them ideal for all sleep positions. Whether I’m sleeping on my back, side, or stomach, these pillows adapt beautifully and keep me comfortable throughout the night. They’re also breathable and skin-friendly, which is a huge plus for anyone with sensitive skin. After using them, I wake up feeling well-rested and free of neck stiffness. I like it.

Pillow
These DIORIS pillows are a game-changer! I’ve tried many pillows over the years, but these are by far the best. The down alternative fill is incredibly soft yet supportive, providing just the right amount of fluffiness without feeling too firm or too soft. I sleep on my side, and these pillows cradle my head and neck perfectly, giving me the support I need for a restful night. They’re breathable and skin-friendly, which is great since I tend to get hot while I sleep. The queen size is just right for my bed, and the pillows maintain their shape night after night. They feel like luxury hotel pillows! Highly recommend for anyone looking for a comfortable, supportive, and durable pillow.

this pillow does work
For months my neck had been brothering me every morning when I woke up. Figured it was stress and I always planned on getting a massage. But I never did it. I ended up seeing this pillow on Amazon and got it. It was almost an instant 180. My neck pain is gone! This pillow is stuffed very full but isn't super firm. It's a bit hard to describe. The seams are well sewn and the pillow has held up very well for a week now. No weird smells or any type of red flag that I found. It's easy to flip and reshape in an instant.

Comfortable to use with firm support
This set of queen-size pillows has a great balance between softness and support. The down alternative fill feels plush and comfortable. The pillows also provide enough firmness to support the neck and shoulders. A better sleep quality achieved with less tossing and turning. For sleeping on side, back, or stomach, the pillows keep their shape and offer consistent comfort. A good choice for the improvement of sleep quality with more comfort.
