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,

  • 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:

Very relavant for today's times
Format: Hardcover
I sometimes felt isolated when it came to reading the bible and then looking up at the news and seeing the parallels and then I found this book. Then I discovered Turning Points and the best minster I ever listened to. Unfortunately he is in San Diego but thanks to modern technology I can listen to him anywhere and anytime. I'm a history buff, but the stories he pulls from the past are none I had heard. His knowledge base of the bible is unmatched in my opinion. He brings past events, the modern nightmare of the world and the bible all together. You can't put it down. After your done you don't feel scared because you know where your salvation lies. It just feels better when you know someone older and wiser than you sees what you see. Now the book will make the round of a small circle of my Christian friends.

Timely message of hope.
Format: Kindle
This is a timely book for Christians and non-Christians alike due to the anxieties related to the chaos of this present world. Anyone who is asking, " Is this the end?" Can find a lot of information that could serve to challenge preconceived ideas regarding scripture and it's viability to what we are currently experiencing in this world. It's a book of hope for those who feel hopeless. It offers clarity to those feeling confused. It places all we currently see within a very detailed historical context that allows us to see the big picture as well as connecting history to prophecies regarding the future. Definitely a good read.

Small group study
Format: Hardcover
Some were apprehensive in our small group of 18 due to the initial appearance of negativity of the world. BUT, we are all in and getting our heads out of the sand to understand what is going on in the world around us. It is eye opening. It is good to read, discuss and be aware. Excellent study.
