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).

Kitchen accessory holder
Color: Black
This is a black dishcloth and accessory holder made of steel. It has a wire bin with an angled bottom plate to allow water to run off into the sink rather than pool (a plus!) It has a bar that clips on and hangs across the front to hold our dishcloth. We put a hand soap dispenser in along with sponges and a scrubbing pad. It does come with a clear plastic sticky strip with molded catches if you want to hang it in the sink, but we set ours on the top of the sink. Works well and doesn't move around or fall. A nice kitchen gadget.

Perfect sink organizer, keeps everything dry and clean
Color: Black
I honestly didn’t realize how much I needed this until I got it. My sink area used to always look messy with wet sponges, soap bottles, and water all over the counter. This sink caddy completely fixed that. It keeps everything in one place — my dish soap, spray, sponge, and even a towel — and allows everything to dry quickly instead of staying wet. I also like that it’s sturdy and doesn’t take up too much space. It makes my kitchen look more organized and clean without any effort.

As advertised. Good size for my sink area. Room for dish soap, hand soap pump and kitchen sponge. A place to hang my kitchen wash cloth too.

Very sturdy and well designed organizer
Color: Black
Sturdy kitchen sink organizer. I measured and it truly is small. It holds large bottle soap, smaller bottle of cleaner, small round dish brush cleaner. The rack clips to the front and folds dish cloth. The tray slants toward sink for water to drain easily. I could have used a few inches longer. This makes a difference and I recommend for its sturdiness and useful design.
