Peristaltic Pump Simple

prusaprinters

3d print a simple waterpump! This is a peristaltic waterpump with high pressure and low waterflow. I used it in a small automatic greenhouse where it connected to a spray nozzle. Hardware required:Yellow TT-motor (ideally low rpm and high torque)M3-Screws & NutsWasher (not necessary)Silicone-tubing (5mm outside diameter)Tips when building:Apply a light coat of grease on the pins where the rollers are mounted and on the roller-support screw. I can recommend using some metal-tubing to prevent the silicone tubing from moving. The rotor is a tight press-fit on the tt-motor shaft. Print 3 rollers. Supports:Supports are needed for “Housing”, “Housing 2” and “Rotor”
