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).

Sturdy and cute!

So easy to install. It was my first time using drywall anchors and it was a breeze. Only the middle screw is in a stud and two other screws in anchors. They are very sturdy. Very pleased with this purchase. I bought a second set for our second bathroom too.

These are beautiful. Great choice
Color: Black, Size: 24"W x 6.5"D, 2Packs
I initially had brought these and had to return them, because I brought the wrong size. I returned them and got the correct size. I love them, they are very sturdy and well made. They are easy to install, looks great and the size was perfect too. They are great and are worth every penny. I DEFINITELY RECOMMEND THEM and will be getting another pair.

Decent enough, but needs better anchors
Color: Rustic Brown, Size: 27.5"W x 6.5"D, 2Packs
The included wall anchors are brittle. One out of 8 would shatter just on screwing them into drywall. All of them shatter and strip from driving the screw in. That said, the bracket holds, and the shelves are nice for dry locations. Thin fiberboard with thin vinyl veneer, tilted very slightly towards the wall. Each kit comes with a magnetic level, and each shelf comes with an extra screw, anchor, and securing screw. Easy to intuit how to install, but includes easy instructions for those who do best with visual examples. I got 8 shelves and am content with them.
