This is another variation of peristaltic pump.

I used HS-755MG servo whose electronic was broken and connect power supply (5V) directly to the motor. Next "vitamins" is 6pcs of 625 ball bearing, several M5 screws and nuts, M3 threaded rod and spring as you can see on images.

As tubing is used standard silicone aquarium hose of diameter 4/6 mm (INT/EXT); servo has enough torgue to handle it.
