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 sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head and displays them in plain text in the alarm menu. FCM measures the actual pressure and flow rate and eliminates the need for additional monitoring and control devices (accuracy of ± 1.5 % of the set value in a trouble-free process). The measured pressure and flow are displayed and can be integrated into the process control system, e.g. SCADA. In addition, the AutoFlowAdapt function automatically adjusts the pump speed to the process conditions to maintain the target flow even with fluctuating back pressure or air bubble formation (degassing drive strategy). 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,
  • A pressure sensor.

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:

  • The sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head.
  • Measurement of actual pressure and flow.
  • AutoFlowAdapt automatically adjusts the pump speed to the process conditions (what you set is what you get).
  • Degassing drive strategy in case of air bubbles detected in the dosing head and Auto Deaeration during pump standby avoids stand-still due to air-locking.
  • ConditionCheck analyses the pump and the system where the pump is installed.
  • 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 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).

Excellent Handbook!
Format: Paperback
This is a great book for anyone from beginner to seasoned activist. Kazu Haga breaks down Kingian Nonviolence and other justice and healing modalities in a way that makes them very accessible to a wide array of readers. I plan to give this to several elder activists - and my 14 year old niece. Haga breaks down the Six Principles of Kingian Nonviolence, Restorative Justice/Practices (RP), separates & defines four types of conflict as well as other clarifying enumerations of large concepts. As an RP practitioner, I found his handling of restorative work to be excellent, and I found the Kingian principles revelatory and beautiful. Kingian Nonviolence dispels the myth that nonviolence is passivity "Nonviolence is not about what not to do. It is about what you are going to do", and has clear steps toward justice and conflict work that have proven efficacy. Haga's handling of nuance and contradiction is unique and powerful, as well as his personal approach to understanding alternate perspectives (listening to right wing radio on regular basis - with an open mind -for instance). More than one thing can be true at the same time, we can expand to hold contradiction, and still seek accountability and healing. The clarity of why shaming and punishment doesn't work for preventing future harm, or healing harm that has occurred is present not only in the concepts in the book, but his personal experience via years of offering trainings in prisons. There is still a lot of resistance to RP and nonviolent approaches to harm - especially in Law Enforcement and Corrections, and I think the accessibility and clarity in this book are useful to help naysayers possibly see the light of why these healing and justice practices ultimately protect us all.

This is the one
Format: Paperback
If you read one book this year about how to deal with conflict, this is the one. His language is crisp, his examples simple to understand, his reasoning is easy to follow. Best of all, he interprets Dr. King's Philosophy of Nonviolence through his own, hard-won experience with organizing in Oakland, CA, Occupy Wall Street and myriad other struggles. All that experience has taught him that Dr. King was right to focus on relationship building. Kazu asks the hard questions, toughs out the answers, learns from myriad mistakes and shares his hard-won lessons with us. He also references some great resources. I gave this book 5 stars. Normally I would have awarded 4 stars, because there are some typos sprinkled throughout the book. However, I added back that star because the book is so very well-written, absolutely authentic to the Kingian Nonviolence curriculum, and urgently useful NOW. Kingian Nonviolence (not non-violence) is more useful and effective than any other strategy, for the long-term, and often for the short term as well. Let's build this world of Beloved Community. Thank you Kazu, Dr. Lafayette, and Dr. King, for giving us a head start.

The Inner Game of World Changing
Format: Kindle
This book bridges the gap between activism and spirituality, making the argument that the world will never change for the better in a lasting way without both working together. Yes, the systems of injustice must be dismantled, but it will be impossible to build new systems that work for all without the inner foundations spelled out in this book. Yes, we need to love one another, but we also need to deal with the material realities of injustice and oppression. Without the principles laid out in this book, we are left with a toxic culture of shaming and ineffectual anger on the side of the activists and a loving but disconnected-from-reality culture on the side of the spiritual while the violence-fueled industrial-growth complex goes on wreaking its destruction. If you despair of things ever changing for the better, read this book. It's THE way forward.
