Forgun DC 12V D3 Peristaltic Dosing Pump 3x5mm DIY Head Tube for Lab Analytical Liquid

in a previous project video of mine I showed you how to create a crude cocktail machine the most important components of the system were three peristaltic pumps those are basically motors to which mechanical structure is attached which compresses a silicon tube while the motor shaft is rotating this way a pressure difference is created which can force liquids through the pump without their touching any mechanical parts that makes such a pump suitable for clean / sterile or aggressive fluids and best of all it delivers a precise amount of fluids per minutes in my case around 525 liters per minutes now while all of that sounds fantastic the price of those particular pumps is certainly not move around $30 per piece that do exist cheaper versions though but their flow rate is also around five times smaller so in this episode of DIY or buy we will try to create our own peristaltic pump which
