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.

  • Manual dosing in ml/h, I/h or gph.
  • Pulse control in ml/pulse (incl. memory function).
  • Analog control, 0/4-20 mA (scalable).

  • 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.

Soft and fluffy after a wash & dry
Color: 02 Ashley Blue, Size: Throw XL (50" X 70"), Color: 02 Ashley Blue, Size: Throw XL (50" X 70")
Perfect, lightweight and warm. I got this for a chaise that I use. It’s not thick, but enough to keep you warm and cozy if you’re just reading and relaxing. I washed it and dried it as soon as I took it out of the box. It fluffed out perfectly, so don’t be fooled by the flattened squishy blanket that arrives. It doesn’t shed, which is a bonus.

High Quality Comfort!
Color: 01 Sage Green, Size: Queen (90" X 90")
This is definitely one of the most comfortable blankets I have ever owned. The material is thick, soft, warm, durable, and resistant to shedding & fibers breaking off. All of these favorable qualities work together to create optimal sleep conditions, and I would say it protects against cold temperatures in the environment (natural air & A/C, for example) very well. It is SO extremely cozy!!! It has become a comfort item of sorts, as well. It fits my Queen-sized bed absolutely perfectly. I've been searching for a blanket to fit my entire bed, and this blanket most definitely is the one. When this blanket is nearby, it's nap time! I love the the slightly raised texture of this blanket's material, and the checkered pattern adds a subtle, yet stylish touch to its overall appearance.

Loving my Bedsure Blanket
Color: Cream, Size: King (108" X 90")
I love this blanket. It’s for summer use & is the perfect weight. I feel both cozy and cool! Plus color & size are as shown. I washed it immediately and it was easy & came out soft; no shrinkage or shedding in the dryer.
