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.

Well written and eye opening
This book is easy to read and easy to comprehend. The writing is attractive and helps the reader understand with ease the challenges and difficulties in relationships with their significant other and or other people in their lives. After reading this, I believe love is perception based and it is a matter of just changing how you see things to understand and feel loved. The part that hit close to home for me was in the end where a man who had gone to prison had wrote the author to tell how he had never felt love from his mother but after reading the book, realized she had loved him all along but not in a language he spoke and it wasn't until he was about to be locked away from her that she spoke to him in the language of touch and opened his mind. It brought tears to my eyes because I identified myself with that man having that internal struggle When Love Was there all along. Love is the motivating factor in practically all of our life decisions. With it, we feel we can conquer the world and without it we feel abandoned and scared. It is all a matter of perception. Love yourself, love your family, love your friends, and all those that are close to you and unknown to you and the world is not such a scary place after all. This book is definitely going to be on the top of my shelf.

A quick and interesting read. It may help you broaden your horizons with relationships!
There is no real difference in terms of what you will take away from this book if you already read the original. This book gives you some manly homework, some insight into conflicts with perspectives that I did not think of. Suffice it to say, reading this book helped me grow as a person and helped with my relationship. You come out on top as a man since this book helps keep your cool. Basically what I'm trying to say is: If you never read any Love Language book and you want a more man-centric read. Get this and live it.

Bought as a gift
The young man is using the book to understand that we all have different love languages and I watch as he take interest in the content of the book. I gave both my daughters a copy last Christmas as part of their gifts as well. I have my copy of the book and it has helped me to understand others as well as myself more profoundly. Everyone one should get a copy for themself…a must have to help build better relationships.
