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 sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head and displays them in plain text in the alarm menu. FCM measures the actual pressure and flow rate and eliminates the need for additional monitoring and control devices (accuracy of ± 1.5 % of the set value in a trouble-free process). The measured pressure and flow are displayed and can be integrated into the process control system, e.g. SCADA. In addition, the AutoFlowAdapt function automatically adjusts the pump speed to the process conditions to maintain the target flow even with fluctuating back pressure or air bubble formation (degassing drive strategy). 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,
  • A pressure sensor.

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:

  • The sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head.
  • Measurement of actual pressure and flow.
  • AutoFlowAdapt automatically adjusts the pump speed to the process conditions (what you set is what you get).
  • Degassing drive strategy in case of air bubbles detected in the dosing head and Auto Deaeration during pump standby avoids stand-still due to air-locking.
  • ConditionCheck analyses the pump and the system where the pump is installed.
  • 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 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).

Spicy little organizer
Size: 7.4" - 3 Drawers (2.2" each drawer), Color: Black, Size: 7.4" - 3 Drawers (2.2" each drawer), Color: Black
I just love being able to organize a cupboard and make it neater and more efficient. This spice rack is just the ticket to help me do just that. The rack is very well made. The drawers slide out easily and are very sturdy. It was so easy to install - there was really no assembly required. It holds 30 of the average sized spice jars. Not only is it very functional, but it looks really good, too. Finding my spices will be much easier now. I would buy this product again. It was a really great price and a very good quality.

Great product & strong tape! Just check the width if ALL of your spices will fit first :)
Size: 7.4" - 3 Drawers (2.2" each drawer), Color: Black
It's great! I didn't have to put it together, it was already assembled. Organized my spices in the cabinet making it look way more neat and easier for me to access ALL my spices. It comes with the two-sided sticky tape that helps it stay in place. Only two things I would say is be careful when placing the rack with the tape down and wanting to pull it back up to rearrange or move it, the tape is really strong, and check the width of the organizer of where you place your spices because I didn't see if there were wider width options for my bigger spice bottles. Other than that, still love it :)

Good racks, 2 slides instead of 1, smooth action
Size: 7.1" - 2 Drawers (3.3" each drawer), Color: Black, Size: 7.1" - 2 Drawers (3.3" each drawer), Color: Black
Pros: 2 sliders instead of just one, smooth action on the slides, slides ‘lock’ into place when retracted Cons: none for me, other than no option for a single drawer in this size Needed a wide 2-tier rack to go along with other racks I bought at the same time. I chose this one primarily because: - it has 2 sliders, instead of a single one in the middle. - it’s shorter than others I looked at and I needed to fit some taller items. - there’s only screws attaching the sliders to the base, which I was going to remove to reduce height. I really only needed a single 2-tier rack in this size, but it was only offered as a double. Fortunately, the sliders were only affixed to the base with screws and not rivets, so dismantling a single drawer was easy and didn’t require doing any damage. If you happen to need to do the same, but still have to use the base to clear a lip at the bottom of the cabinet, the metal of the base should be easy to cut in half if you have or have access to the power tools to do so. If you don’t, you could still dismantle 1 rack and just create a new base with some thin wood, then screw both directly to the cabinet. No complaints, would buy again if it were offered in a single-drawer configuration. Having 2 slides was still definitely a big plus, nonetheless, but I now have half a unit that I don’t necessarily need. I would note that the sliders don't extend quite as far out as I thought they may, but it's really only ≤1" that I'm talking about and they still extend far enough to vertically pull the rear-most item out, so it's not a biggie, just worth noting. * I didn’t use the adhesive strip and just threw it away, as I intended to secure it with screws from the beginning. If you’ll be using the base, I’d suggest drilling holes through the base and securing it to the cabinet with screws. The adhesive could well be fine, but it’s asking for trouble to have this loaded with glass and have the adhesive give out. No doubt it would happen when you have 3 things on the stove, the phone is ringing and it was the also week you kinked your back something awful, right? (Item reviewed: 2 drawer x 3.3")

Excellent quality / size.
Size: 7.4" - 3 Drawers (2.2" each drawer), Color: Black
You magnificent SOB! This is an excellent product - it is exactly as advertised, saves space, is well-built and the measurements are spot-on. There is no assembly and the double-sided tape works perfectly to stabilize the unit. Great product and worth the price.
