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:

helps my swelling in my ankles and feet
Color: Black, Item Shape: Classic
I was having issues with my feet swelling because I sit all day for work. After using this my feet don't swell like they did. The product is also comfortable. I would recommend this foot rest. The best part is its two and one. You can use the rest or turn it over and rock it with your feet which helps. The foot rest is sturdy and durable.

Very Comfortable & Useful Foot Rest
Color: Navy, Item Shape: Teardrop
This product is a lifesaver for me since I sit at my desk for hours on end. Just the simple act of raising my feet up onto this heavenly soft foot rest makes a huge difference in how my back, legs, and feet feel at the end of the day. Very high quality materials and workmanship. You can also remove the zippered cover from the memory foam pillow and wash it.

Very Comfortable and Supportive, Minor Flaws
Color: Gray, Item Shape: Classic
I’ve been using this ComfiLife adjustable memory‑foam foot rest under my desk for a few weeks now, and it’s made a noticeable difference in how my legs and lower back feel. What I Like: The high‑density memory foam is plush but still supportive, conforming nicely to my feet whether I wear shoes or sit barefoot. Under Yours +2 ShipItFurniture +2 The adjustable height feature is super helpful — you can add or remove a base layer (2-inch detachable bottom) to set the footrest exactly where you want it. ComfiLife +1 The removable cover is machine washable, which is great for keeping it clean. Under Yours The bottom has a non-slip rubber surface, so it stays in place nicely under my desk. ComfiLife It’s multipurpose: you can even flip it over and use it as a rocker or support it under your knees. Under Yours What Could Be Better: Because it’s memory foam, it compresses a bit over time—not a deal-breaker, but you’ll notice it loses some height after prolonged use. ShopSavvy While the height adjustment works, I found it a little less stable when fully extended. ShopSavvy The fabric cover can collect dust or dirt, so you might need to clean it more often than a plastic footrest. Fakespot Overall: This footrest is a strong pick if you spend a lot of time sitting at a desk and want something soft, supportive, and adjustable. It’s not perfect, but the comfort and ergonomic benefits are absolutely worth it.

Comfortable, Adjustable, and Great Value!
Color: Gray, Item Shape: Teardrop, Color: Gray, Item Shape: Teardrop
This footrest is exactly as described. The two-piece design offers excellent flexibility, allowing for multiple configurations to suit different needs. Both pieces are comfortable and adjust easily as intended. I’m especially glad I chose the teardrop style—it works perfectly for my setup. I’ve experimented with several of the suggested configurations and can see how the various options would accommodate different preferences and ergonomic needs. For me, this was an ideal choice. The overall design and construction appear to be high quality and durable. When used with socks, the surface is very comfortable, and the base grips the floor securely when in use. Overall, I believe this product offers great value for the price.
