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.

  • 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).

Entertaining and helpful lessons
Format: Hardcover
My family loves this book. Used to read it to my daughter as a young girl and now she’s a teen. We still talk about the lessons learned in this book! The characters and illustrations crack me up: Smash, rip and ruin taught us a lot! And the ones without hands and noses! I couldn’t believe how long ago this book was written when we got it- all lessons still applicable today.

... over with my 3yo and 5yo boys but they loved it!
Format: Hardcover
I wasn't sure how this would go over with my 3yo and 5yo boys but they loved it!! They always enjoy pulling it out and now I can refer back to the characters to remind them of their manners in a more positive way. The only thing is I kinda wish they had used a different animal than pig, since for some reason I don't like saying "don't be like the pigs" (since I don't really want them calling eachother or other kids pigs). But so far it has been fine :) It's also very nice they included "Be kind to animals, they have feelings too." We say that all the time around here since we have kitties. Also the part about table manners is great since we had already been teaching the kids to ask before being excused from the table.

Manners Can Be Fun
Format: Hardcover
What a cute book! I bought it for my 2 and 3 year old boys. We are attempting to teach them simple, common manners in a fun way and they love learning through books. Manners Can Be Fun presents manners in a simple, easy to understand, engaging way. The boys enjoy reading this book and it's a great way to have positive conversations about specific situations they experience daily like sharing toys, picking up after themselves, whining, meal time. It's a fun book!

Wonderful, simple book for children of all ages
Format: Hardcover
I am 65 years old and this was one of my first books. The revisions along the way have not changed the drawings that much. It is simple, but well illustrated, and gives a basic idea of good manners. I recommend it for every child - it makes them think about behavior. The way the author demonstrates "me first" and "whinney" have stuck with me all these years.
