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).

hard to read display, no manual included.
Color: Black/Black/Digital
I haven't decided yet whether or not I will keep the watch. Problem is there is no instruction manual attached and you cannot find one online. However if you call Timex support they will email you the manual if you give them the model number which is included in Amazon's product description. However even with the manual watch is very hard to set. It lacks some functions normally Timex has like time can only be set up there is no down button. And most importantly display is minuscule. So it is really hard to read to set. Watch is a ladies watch. It is small and I like it a lot. But buttons are hard to operate and it is hard to read.

My boyfriend loved it!
Color: Ingram Black
I have total and complete confidence that you will be 100% satisfied when you purchase this product and begin to use it. I will definitely be buying more products from this vendor again in the near future. I would highly recommend this seller to everyone including my friends and family members. I was searching for a new wallet for my boyfriend for his birthday and wanted one that would accommodate all of his cards. His old wallet was falling apart but this one does not seem like it will do that as it is such good quality and seems to hold a lot of stuff inside it. He was super happy when he received it and has been using it for about a month now and it still looks good as new. I’m thinking of getting this for other members of my family who need a new wallet. The leather is smooth and in great condition, no imperfections. The trifold is perfect for anyone who is looking to store a bit more in their wallet. I shopped around for a bit before choosing this one and I’m happy I chose this. Fossil really does make great products and I’m sure I’ll be buying more in the future. I like the simplicity of the design; it’s not too flashy but nice enough to show that it really is high quality. Young or old, any man (or woman) will be pleased with the purchase or gift of this wallet. I also really liked the color as it was super rich and dark looking, not dull at all. Really great and a staple for any man (or woman) looking for a new and sturdy wallet. The shipping for this product was just on time as promised and the product was just as described so that is great!! It just works just perfectly and it is exactly what I was looking for! What an awesome product, I’m glad that I came across this product when I did. This is a great product to invest in, as it is very affordable and seems like it will last for a long time – you should try it out. My reviews are my very own opinion of the product received and just my opinion. Everyone is different and could have a different opinion of a product. I do not receive any monetary payment for my reviews, and I always keep them honest. Therefore, you have no need to worry about whether or not my review is genuine, because I’m telling you, it is. If after my initial review something changes I DO make sure that I go back and update the reviews, for good or bad reasons. I am under no obligation to provide a positive review and received no incentives or rewards for doing so, as I previously mentioned. My aim is to highlight features and drawbacks that I would want to know about as a buyer, not hype the product for the manufacturer to increase sales. My remarks are sincere and true. I work very hard trying to write insightful and thoughtful reviews for each item. My hope is that these reviews are helpful to others who may be interested in potentially purchasing this product for themselves or as a gift for others who may be interested in the product. Please let me know how I am doing by voting “YES” if you think that my review helped you in any way. If it did not, please comment with how I can improve because this helps me to be a better reviewer. I hoped you enjoyed reading.

Timeless design with excellent quality!
Color: Wilder Black
I love the sizing and material, it feels well made and durable. While some might find it a bit small, I think the size is just right for its purpose. It’s practical, stylish, and the simple design makes it look great anywhere.
