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.

Cute and company, but packing makes it VERY wrinkled
Color: Black, Size: 16 Inch
The bag is really cute and designed so well, can't believe how spacious it is yet compact! Not bulky and doesn't take up much room, lots of pockets. Perfect for both fashion and function. Took off stars thought because it came folded in half in its package and it's VERY wrinkled. Kind of takes away from it's look and makes it look bad :( pretty major wrinkles everywhere and I'm not sure if it can come out in this material, though I will try ironing it. If the company shipped it better it would be 5 stars.

Great stylish work backpack
Color: Black, Size: 16 Inch
I’ve had this backpack for a year and a half now and it has held up very well. I use it for work and work trips. It has many pockets for organization and fits everything I need including my 14 inch work laptop. Very stylish (not sporty) and appropriate for the office.

i love my new work bag
the fabric was water resistant and none of my belongings got wet under light rain. it fit my laptop, chargers, notebooks, two toiletry bags, plus a puffer vest and a wool tucker jacket. it got me through international customs and TSA quickly. when asked to search my bag for liquids prior to boarding an international flight from south america to the US, the agent complimented my bag, and i made record time through the line and to my seat on the plane. the zippers work great and have yet to fail me. lightweight and surprisingly sturdy. do be advised that the lighter colors will take on some damage after a few dozen bus rides, but it’s to be expected and i’m not mad at it. great purchase for the price !
