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.

Top quality low budget watch!
The one thing budget watch collectors should know is that this Casio model is the only watch under $25.00 that comes with a mineral glass screen and not that cheap Acrylic plastic screen that scratches easily. It's also a 200 meter WR watch which is about 2 football fields in depth if you love snorkel diving off the coast. The screen visibility of reading the time and other features is outstanding. It also has 4 time zones you can program in , 5 Alarms, count down timer and stop watch. You can set it for 12/24 hours time format. I always order the steel bracelet that comes off another model of this because it not only looks and feels like a top quality watch but also matches the steel bezel. Do not buy the negative display version because it's unreadable.

Casio's best yet!
Casio is by far the best digital watch company in the world but it just seems like this watch wins it all. The upcoming list is of reasons why I think this Casio watch is the best one you can buy. Reason One: The price is unbeatable! I have never seen such a great watch for the price of $13! And coming from Casio you know it won't be a rip off! There are plenty of other Casio watches that can do the same thing that this watch can do for a price twice as much! With a price like $13 nothing can go wrong and it won't be such a bummer is you don't like it overall. 5/5 Reason Two: The amount of things it can do. This watch is capable of doing world time in twenty different spots worldwide, you are able to bookmark your four most favorite spots (one of them being were you live), it has five different alarms with exceptional sound when it goes off, and it has a timer and stopwatch that can go to up to 24 hours. This watch was obviously built for a busy life style. 5/5 Reason Three: Its water proof and has ten year battery. This watch is water proof up to 200 meters under water so you definitely won't need to worry about your watch getting destroyed by water. Its ten year battery makes it so that you won't need to replace the battery for quite a long time. 5/5 To sum it up this watch is cheap but not cheaply made, has world time, five alarms, a stopwatch and timer, can go under water for 200 meters and has a ten year battery! This is worth the buy!

100% functional watch
Light is subpar , but a 100% functional. Digits size is fine (I am 60). Labels could be brighter, but Casio rarely does modifications to these models. My dad has the same model, now over 15 years.
