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).

Machine stopped working after factory warranty expired
My Cricut Maker 3 stopped working after 2.5 years and luckily I had bought this insurance for 3 years. I summited my claim and Asurion provided a UPS prepaid shipping label, I had to pack the machine and send it but I did not have a box beg enough to put the machine so it took me around 5 days to find one. When I tried to print the shipping label, it was not working so I contacted Asurion customer service, the customer service associate was very friendly and helped me to get a new shipping label. Did no have any issues, so would recommend to get this protection in case your factory warranty runs out.

NO WARRANTY EVEN IF YOU PAY EXTRA FOR IT.
Beware I purchased a casement window air conditioner AND the asurion 3 year warranty extension for the unit. The air conditioner was faulty from day one in that the temperature control did NOT control temperature and the compressor would not stay on unless the unit was set at the minimum 62 F setting. I called the manufacturer/distributor of the air conditioner and they informed me that there was NO WARRANTY on the unit because it was sold by a third party. The unit was only warranted if it was purchased directly from the distributor themselves. I then checked with the extended warranty company *asurion" and was told they would not warrantly the product until after 12 months subsequent from purchase. I highly suggest that anyone concerned with receiving a working product from Amazon should take care to investigate thoroughly before placing an order. I contacted Amazon and they will replace or refund these items however I see no choice but to get a refund. Replacement with a non-warrantied product seems like something even a very foolish person would not consider. Asurion's policy on not honoring it's extended warranty until 12 months after purchase is also hmmmmm unusual and makes their warranty products a questionable purchase.

Prompt service
Excellent service and got my refund via e-gift card. My portable ac heat combo unit failed after almost 3 years of use and I was refunded my purchase price. It’s easier to claim using their chat support.

Amazing, effortless, easy!
Excellent experience! I made a claim and they immediately issued an Amazon gift card for reimbursement. Entire process from start to finish was probably 2 minutes or less. Amazing, effortless, easy! Will purchase again for any other items that qualify.
