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.
  • Multi-parameter dashboard function to provide further information on up to 4 parameters.
  • Counter for total dosed volume (resettable), operating hours, etc.
  • Save, copy and load customised settings as well as reload factory settings.

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).

Am almost done reading
Format: Hardcover
This book came recommended by a very hospitable friend. I'm almost done reading and wanted to drop by here to leave a positive review. Lots of good useful ideas in this book and it has an engaging writing style. I think the author is specifically gifted in the area of hospitality - not everyone can live like she and her family do, but there are a lot of practical tips if you're hoping to grow in that area of your life.

Hospitality is the Most Important Thing
Format: Hardcover
The author does an excellent job making a case for how important and underrated hospitality is to a hurting world. She captures my attention instantly with her story about her neighbor Hank. She leaves me hanging through a couple of chapters before I get more details about his story. I almost put down the book permanently when she gets on her high religious horse. I suspect she and I would disagree about some of our theology. And I didn't need to be persuaded, so those chapters weren't written for me. If you skim (or skip) that beginning section, it's well worth the practical ideas for how to open up your own home and life in hospitality. A great challenge that I shall take up. May all our neighbors become friends and our friends become family.

Didn't Notice Difference
The taste is actually pretty good, honestly it's more like a treat than a supplement... but I haven't noticed any significant changes after going through the entire bottle. They didn't cause any upset stomach or side effects, which is a plus, but the overall benefits feel negligible.
