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).

I like the content
Good for my biblical education. The book was recommended by a Pastor who visited the church. I read it and found it very informative and inspiring. These books are worth reading continuously. And more than just reading its content must be acted upon.

Awesome Beyond Mere Words
Format: Paperback
Unaware of its full content within, I found this book has revolutionized my inner self's awareness: of WHO I am in Christ, and Who's Inside Me and has been since accepting Christ! This book helped to 'show the way' how; to convert from academic "knowing" thinking to "Spirit-led living." This is a major transitional shift, but one God wants, the Spirit led me to, and what my prayers had been asking for all along without MY-understanding even realizing it! until I 'let go of MY-understanding and let Holy Spirit have the upper hand. It's really a "tuff job!" but one 'worth fighting for'; by letting go. With His 'Power' within, there's no other way but UP. I strongly recommend this book to those seeking a closer/deeper connection with Jesus Christ and God's Holy Spirit. The wording is so very easy to read, yet its depth very profound.

The Supernatural You
I was pleasantly surprised by 'The Supernatural You' by Brenda Kunneman. She exposes you to the power that every believer has inside of them, but is rarely teached in the average church. She talks about her growing up and how she learned about this supernatural power. Very practical tips on how to access your hidden power. I would recommend it to other Christians that want to go deeper in God. Ironically - I hit "Buy This Book" by accident. Now I realize it wasn't an accident....

Biblically sound, step-by-step instruction
Format: Paperback
If you're ready to challenge the current, prevalent (and wrong!) paradigm, this book may be for you: Yes, it IS possible for modern-day, born-again Christians to live in miracles as did the first apostles after receiving the Holy Spirit (Holy Ghost) at Pentecost. This book guides you through the process of stepping into that full, abundant life promised by God.
