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 sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head and displays them in plain text in the alarm menu. FCM measures the actual pressure and flow rate and eliminates the need for additional monitoring and control devices (accuracy of ± 1.5 % of the set value in a trouble-free process). The measured pressure and flow are displayed and can be integrated into the process control system, e.g. SCADA. In addition, the AutoFlowAdapt function automatically adjusts the pump speed to the process conditions to maintain the target flow even with fluctuating back pressure or air bubble formation (degassing drive strategy). 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,
  • A pressure sensor.

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:

  • The sensor-based FlowControlMeasurement (FCM) system detects malfunctions such as air bubbles, line breaks or overpressure directly in the dosing head.
  • Measurement of actual pressure and flow.
  • AutoFlowAdapt automatically adjusts the pump speed to the process conditions (what you set is what you get).
  • Degassing drive strategy in case of air bubbles detected in the dosing head and Auto Deaeration during pump standby avoids stand-still due to air-locking.
  • ConditionCheck analyses the pump and the system where the pump is installed.
  • 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 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).

Surprisingly good
Size: Gravity, Color: Deep Space Grey
I bought a very old Lexus as a second backup car and as such, it doesn't have any of the amenities we are used to. This phone holder is surprisingly smartly designed. Every time I put my phone in it I'm impressed that it holds it in place.

Outstanding! 5 Stars for Mobility, Durability, Functionality and Ease of Use.
This little invention is outstanding! It holds phones of multiple sizes very securely in place without any bonding or sticky attachments that could damage your vehicle. Mobility is simple as it's easy to add and remove to any vehicle with air condition vents. Best of all, various size devices can be easily held in place with a quick squeeze of the side mounts and just as easily removable with a single press of a release button on the back side. The mount is also very strong and holds up to various temperatures. For example, in the summer it can become very hot in an enclosed vehicle and this mount holds up when other mounts tend to fail from over exposure to heat. The failure causes the joints or fittings to loosen, which will cause your device to slip from an intended position. Well, that is not a problem with this one. It has stood the test of time as I have used this mount for over a year in extreme environments. In the end, it appears that my family has come to like this product too. Ahem, my wife just took mine! So, I have returned to purchase another one for myself and two more for my daughters. Then I don't have to worry about my daughters taking mine either. Yes, I'm finally thinking ahead, so maybe you should think ahead and get additional copies for your family members. Either way, try one and you'll likely be back for more. It makes a great gift. I highly suggest this product to everyone who needs a mobile device mount for their vehicle.

Excellent Product and Exceptional Quality and Service – Highly Recommend!
I recently purchased the LISEN Car Phone Holder Mount [Military Stable] and couldn’t be more impressed! From the moment I unboxed it, I could tell it was built to last. The design is sleek and modern, and it holds my iPhone 15 Pro Max securely without any wobbling, even during bumpy rides. The military-grade stability lives up to its promise—this mount stays firmly in place, and the adjustable clamps fit my phone perfectly. What really stood out to me was the ease of installation. It attaches to my car vent effortlessly, with no tools required, and doesn’t block any air flow, which is a huge plus. It’s also compatible with various phone models, including the latest iPhone 16, so I know it will be a long-term solution for my future upgrades. In addition to the great product, the customer service from Linsen was outstanding. They provided timely and clear communication, answering all my questions before I made the purchase. It’s rare to experience such excellent support these days, and it made my buying experience even better. If you’re looking for a reliable, sturdy, and easy-to-use car phone holder, this is the one to get! https://www.amazon.com/dp/B0CXLQDY5B Highly recommend!

Well made, but not a good fit for Volvo XC40
One issue with this style of holder, is that the swing arm and holder add a fair amount of weight and extends that weight away from the vent, applying quite a bit more leverage on the vent. It may not be as much of an issue on horizontal vents, but the vertical vents on an XC40 will want to swing side-to-side with all that weight. As for the build of this particular holder, my only real gripe is the adjustment for the swing arm - after tightening the knob, there will still be some play in the arm...you have to jiggle it while tightening it down to fully secure it. The position of the release button allows one-handed removal of the phone, but really only works by pinching with your thumb on the screen. The clip for the vent accommodates relatively wide fins and the tabs can be rotated to help with stability or removed to provide more clearance (though rubberized tabs would be much more helpful).

Good solid product
Purchased in February of 2025. Very solid item. Use it constantly in our 2011 4Runner and 2017 CX5. This unit attaches firmly to vent fins in both cars. I use iPhone for maps programs and streaming music. When traveling I'm constantly rotating device 90 degrees to use phone in portrait and landscape positions. Unit has shown no signs of losing ability to firmly hold desired position despite frequent rotations. It holds firmly where you place it. Initially I had concerns about placement on dash and blocking view of radio face, clock, MPG indicator, and other displays. Didn't take too long to realize the flexibility of this thing and the many, many positions you can place it due to multiple rotational joints. Pricing was fair. If this ever wears out, I will want to buy another.
