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.

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).

Will definitely get more for my pig ear loving boy!
Flavor Name: Pig Ear, Size: 8 Count (Pack of 1)
My shar pei mix baby LOVES these! He is about 4 months old, teething and always has food on the brain. These do the trick! One ear lasts him about 2 days if he is really going at it, sometimes longer. He will work on it for hours at a time. They have little to no smell. He chews them on his white dog bed and they leave no stains or marks. I love that there aren't any extra ingredients so I know exactly what he is ingesting. I will DEFINITELY be buying more of these!

Is Milo allergic to pig ears?
Flavor Name: Pig Ear, Size: 10 Count (Pack of 1)
Milo sniffed the pig ear, paused, and then took it to his spot to eat it. A few minutes later he started rubbing his head on the floor. I also bought the cow ears and he ate them with no problem. I’ve snuck him the occasional piece of bacon so I don’t think he’s allergic to pork. I love and trust Nature Gnaws.

Great quality!
Flavor Name: Pig Ear, Size: 8 Count (Pack of 1)
I do not review items very often, but after considering that I have ordered these no less than 30 times, I decided it was time. I have four dogs who absolutely love them, so I go through them pretty quickly. They are generally very large, with occasionally one smaller one in the bag. These are the best price/quantity pigs ears I have been able to find. Each bag has eight ears. My dogs range in size from a (very food-motivated) mini dachshund to a pit bull, so the treats are good for any size. I order them for my sister’s and my boyfriend’s dogs, and my boyfriend breaks them in half to give to his dog if you don’t want them to have the whole one all at once. Would highly recommend!
