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).

More than a technical guide this book is a masterclass in design leadership using Figma!
Format: Kindle
Sharma's expertise from leading design teams at major companies shines through, offering real-world insights that integrate Figma into a strong design process. What sets this book apart is Aditi’s genuine expertise. She doesn’t just teach the mechanics of Figma—she brings the wisdom of someone who has led design teams at Amazon, JPMorgan, and Walmart, weaving in real-world insights that make the tool feel like an extension of a strong design process. The structured approach, practical exercises, and advanced techniques helped me not only sharpen my skills but also rethink how I lead design collaboration in my teams. For design leaders aiming to elevate their Figma expertise and use it effectively at scale, this book is an essential resource, making the transition both seamless and impactful.

Practical, Engaging, and Worth Every Penny
Format: Paperback
I’ve read a few Figma books, but this one stands out because of how engaging and hands-on it is. It’s written in a way that makes you feel like you’re learning from a mentor, not just reading a manual. The exercises are practical, and the step-by-step approach makes even complex concepts easy to grasp. I also loved the section on integrating plugins and designing responsively for multiple devices—it’s these little details that make a big difference in real-world design work.
