I searched ali express for a peristaltic pump for $1.50. Then I bought it on Amazon Prime for $7.00. Because I want to actually receive it.

  haha, I don't know what peristaltic is, but I'm happy for you!

    It's basically a rubber hose, and rollers that squeeze the hose to push liquids through. The motor runs the rollers. Also means that the liquids don't touch the motor.

      Very common in medical equipment that works with blood in fact

        Very good, it's for a micro-aquarium so I won't hurt any humans if it's cheap (but I take good care of my critters, not to worry).
