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.

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:

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

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 communication interface (integrated Modbus RTU and TCP; Profibus DP, Profinet and Ethernet IP via CIM/CIU models).

You won't be sorry
Size: 10.5-11.5 Women/9-10 Men, Color: Black
Great padding for comfort and terrific warmth. I bought a pair of Acorns 30 years ago and still have them. Updated to a new color and now feel the benefit of newer padding! I used the sizing listed for shoes and like the roominess for thicker sox. Well made and a joy to put on. (Wisconsin)

Extremely comfortable, leather sole. Hard to find a style.
Size: 13.5-14.5 Women/12-13 Men, Color: Navy Blue, Size: 13.5-14.5 Women/12-13 Men, Color: Navy Blue
Totally worth the price. This type of style is very hard to find, my husband had another pair a few years ago that he was never able to replace. These fit his wide feet and are very comfortable. The elastic at the ankle is not too tight. So glad I was able to find him a replacement. We bought the blue in a size 12. Love the fact that they are washable.

Very comfortable Slippers. Great buy!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
I bought these to replace a pair of slippers that I have had for years that are very similar to the slippers I bought, but I had worn a hole in the leather on mine, so I had to find something new and similar. These slippers are worth the money they are very comfortable, and I am sure they will last for years. They are a little tight around the ankle cuff but they are still new and I am sure they will wear in a little more when I start wearing them more.

Great slippers but disappointing quality.
Size: 7.5-8.5 Women/6-7 Men, Color: Ash, Size: 7.5-8.5 Women/6-7 Men, Color: Ash
Extremely comfortable, attractive slippers but the stitching came loose on both leather trim areas almost immediately. I tried to sew/glue down the stitching (as seen in photo) but it kept unraveling. Disappointing as these slippers are great in every other way (though they do run a bit big...I wear a 9 but ended up with a 7.5-8.5 which fits with a bit of room to spare even with thick socks). I just hope they hold up after my latest attempt to stop the thread from pulling out any more as I do really love wearing them. Perhaps I just got a bum pair?
