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.

OBSESSED!!!!!
Format: Paperback, Format: Paperback
I gave it 5 stars because it deserves the flowers. I do wish the paper was a little better quality. I think it would help make the pictures pop more. Regardless, this book is worth every penny. I haven't found anything else like it. The book is clear, concise, and isn't bogged down with too many details - just the facts m'am. It's a perfect starting reference to send someone down 101 different rabbit holes. I hope someday he puts out a hardback version on thick, slick paper with beautiful, glossy photographs. That would be lovely. For now, this will more than suffice. You get just enough about each artifact to get you going. From there, you can decide how to use your favorite search engine.

A great reference for Biblical factual archeology
Format: Paperback
I just received this book and I am so excited. It is a great tool and reference for Biblical studies. Each artifact has a great photograph next to the quick eye catching dates, discovery, period, keywords and Biblical passage. Then a brief but to the point description. It is simple and effective. Very easy to refer when reading your Bible or if you are just interested in archeology. Each artifact is about 2 pages and nothing more which is perfect for references. What a great book!

Excellent and in-depth archeologic finds that authenticate Bible history.
Format: Paperback
Archeology is proving much of the Bible's history as true. This book really delves into various sites and provides a lot of detail. My type of reading.
