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.

Very good LED sign for cars, studios, desks, etc
Size: 1PCS 15''x4''
Great! Item really stands out. This LED sign by Ray home features way more than just devil eyes. There's a lot of pre-built templates for every gig work there is out there for your car. Item was described. A bit dim during the day but at night really shines stands out. You can customize it with uploads withdrawing. You can have programs that animate between the different signage. It's a great product for a car or for your home. To be honest, I can see a lot of uses for this. High quality design. Easy to work app. The adhesive is great for glass. It's reusable plus it comes with strips. If you want to mount it permanently not on glass. Overall a great deal.

Use DUCT TAPE!
Size: 7''x3''
I actually ordered the window signs for cars. Even though it shows different, I got what I ordered. The problem comes in where it shows where they just stick in the window. WELL, THEY DON'T STAY FOR LONG. I drive for Lyft and Uber. I want those signs and need them to stay where I put them. The stuff they send with the signs is junk. USE DUCT TAPE AND BE DONE!
