Peristaltic pump

grabcad

Update: 02 Sep 2019, I've shared the code for an Arduino-controlled peristaltic pump on GitHub. This pump is perfect for precise dosing and continuous pumping of liquids. It's also safe to use with food and other applications due to the tubing separating the liquid from other parts. To maintain the pump, it's easy to access and assemble. I created my own design after reviewing various options and would appreciate any suggestions for improvement. The pump capacity is approximately 160ml per minute, but it can be increased without damaging the tubing. I've included step-by-step assembly photos, and the project started with a user interface utilizing an Arduino Mega2560 and TFT screen. The parts needed include various screws, bearings, and PharMed BPT tubing (see attached image for details). Feel free to ask any questions, and I've also shared the 3D printing files on Thingiverse and additional information on my website. Check my website for more updates, including a video showcasing the pump's functionality: http://karim.lakras.eu/ I made adjustments to the M3 nut holes after printing and marked the triangle sides that lock bearings in place. If you choose to print rollers, ensure their edges are smooth to prevent damage to the tubing. Print settings are available on my website, along with a simple schematic for driving the stepper motor. I'm always open to feedback and improvements, so please let me know if you have any suggestions!
