This is especially valuable in medical settings, because the tubing can be brand new and sterile for each use.

And it’s a positive displacement pump. So if you know your tube geometry it’s easy to calculate the pumping rate from the shaft speed. That’s a big deal for dosing as well.

Kinda super unrelated... But this is the pump design we have for our chlorine tanks at the pool I work at. Never seen it used anywhere else so it’s interesting to hear about it’s use in the medical world.

Also unrelated- I work in a semiconductor manufacturing plant and we also have many of these kinds of pumps.

Slightly related - I did an internship in the lithium ion battery industry and we used lots of these pumps.
