This is a great little pump! It’s positive displacement and self priming. The best part is, it’s reversible!
In the vid, we use this pump to actuate a syringe plunger back and forth.
Out of the box it’ll provide 1.3 Bar of pressure (19 PSI for our American friends). We used hook-up wire to clamp the tiny tubes and got it up to 1.8 Bar (26 PSI). On a 1″ diameter syringe (a big one) that’s enough pressure to lift nearly 10 kg!!!!
Arduino controlled hydraulic robot anyone?
Move fluid safely from here to there with this very nice little pump. Unlike most liquid pumps, this is a peristaltic type – the pump squishes the silicone tubing that contains the liquid instead of impelling it directly. The upshot? The pump never touches the fluid which makes this an excellent choice for any food/drink/sterile based pumping such as for making drink-bots or gardening robots!
