I needed for many things a water pump(liquid pump), I found the peristaltic pump the best for a precision dosing, can be used also for continuous pumping, the liquid is separated by the tubing from other parts, it can be used for food and many applications safely, offers easy maintenance.
After I watched many designs, as always, I like to design my own to see how far I can make it, so feel free to suggest any useful tips!
The capacity of this pump as you can see in the video is about 160ml per minute, you can push this value a little bit it upper, but I didn't want to destroy the tubing.
The pump is easy to assemble, but I attached pictures step by step.
