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).

Powerful and eye-opening
Format: Paperback
A therapist on TikTok recommended this (thank you Kendyl!) and it is easily the most important book I've purchased in years. It pulls together the threads of otherwise "unimportant" early life events and helps to piece together a clearer picture of how those shape our thoughts, feelings, and behavior as adults. It's written for clinicians but would be helpful for a curious client who understands the basics of "parts" work and wants to use this as a resource in conjunction with therapy.

Amazing
Format: Paperback
It’s very academic—what I mean by that is that if you need to be well-educated in psychology to GRASP *everything*… I am not well-educated in psychology (I minored in it and love reading easier books on it), but I LOVE this book. This woman is brilliant

Started w/ audiobook, now I'm ordering the print too
Format: Paperback
This book is GREAT!! The integration of theory she uses to support her claims is masterful. I began listening to the audiobook, because it was cheaper & I go through a ton of counseling & psych books. I am a grad student in social work, and I'm also a therapy client trying to heal myself. I appreciate that this book targets "chronic shame" which as a central experience to a bunch of issues. The hundreds of books and articles I've researched seem like they were mostly ALL working back to this issue. In a psychology culture that is big on cognitive and chemical solutions to mental health, the relational approach that she emphasizes is critical to the healing process. I appreciate the research she uses from object relations, affect regulation, interpersonal, etc. I purchased the hard copy because 1. I can't underline/highlight an audiobook and 2. I want a copy of the references of theorists and study's that she draws from, because they are pure gold. All therapists need to understand the contents of this book! Unless you are perfectly fine offering band aid solutions. Clients and self-helpers beware. It's not triggering in terms of content, it is activating in the sense that she describes the felt experience of shame SO WELL. I could locate my own felt sense of shame which is, by default, unpleasant. Some stabilization and a decent therapeutic connection is probably necessary before cracking this book open. But that's why I love it. I needed to go deeper and get the core issues. And this book is like a map that guides you right to it.

A must read.
Format: Audiobook
The best book I have read in a very long time. Transformative. I am slowly processing my new understanding of my relational trauma so well detailed in this book.
