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,

This is Truly the Best Pillow!
Size: Queen
This is the side sleeper version of the best pillow out there. My 26 year old son was always complaining about his pillow and his neck and back hurting. About every year I’d buy him the next “best” pillow promising to be the best but they never worked for him. I read an article saying THIS pillow was the “Goldilocks” of pillows. So since he sleeps in all positions, I got him the regular shaped pillow. The next morning after his first night with the pillow, he came out of his room talking about how wonderful his pillow is. Same thing the next morning. And the next. And the next. Then I thought to myself, my current pillow is the best I’ve had but I’m not in love with it. But I’m a side sleeper so I purchased this particular contoured pillow for me. NOW I UNDERSTOOD WHAT MY SON WAS TALKING ABOUT. I became the person who went on and on about my pillow. Until my husband told me to replace his with one of these side sleeping versions for himself. And he loves it. Then we got a regular pillow (for those who sleep in all positions, but this same company) for our guests. My best friend came to visit, immediately noticed the pillow upgrade from previous visits and when she returned home, she purchased one for herself. This pillow is like a feather pillow except it is filled with tiny squares of memory foam. And it comes with an extra pack of stuffing, so you can add or remove stuffing to customize it perfectly for you. None of us in the house added filling, and my son removed some that came with his pillow. I also sleep with a body pillow and have for years. And I was wishing this came in a body pillow version until I realized I could make my own. I bought a zippered body pillow case. The larger size. I think it was 54 inches long. And I bought a king size pillow and used the extra stuffing pack that came with that pillow along with the 4 packs that came with the other pillows that we didn’t use. Though you could probably do the same thing with two standard size pillows. These pillows are on the expensive side but they go on sale during every holiday. That’s when I purchase them. Oh and my body pillow is HEAVEN. Between that and the pillow, I spend my nights in fluffy cloud goodness.

Not as great as I was hoping.
Size: Queen
I was hoping this was going to be my miracle pillow. I have had terrible neck pain for years. It arrived with too much stuffing. Removed some and it caused terrible occipital headaches. I’ve slowly been adding stuffing, hoping to find the right fit.

Best pillow ever!!!
Size: Sapphire Queen
I have actually tried dozens and dozens of pillows in my life, and dozens in the past three years, but this is it. Some cheap, some very very expensive, and some very famous brands. This one beats them all. So awesome and comfortable (side sleeper). I tried one and loved it so much I ordered a second right away. It is exactly what I've been searching for forever!!! Stays in shape, extremely comfortable. Only thing is you definitely need a 32" pillowcase to cover it, and I wish they made a 34" pillowcase, but no luck. I used the pillow the same night and it's definitely worth the money. No neck pain, super squishy but supportive, and no odor.
