A peristaltic pump works by using a method called “positive displacement”. Fluid is fed through the tubing by rollers that rotate while squeezing a flexible tube against the pump housing. As the roller moves over the tubing, it expands and creates a vacuum to allow more fluid to enter.

Atlas Scientific's line of peristaltic pumps has been specifically designed for engineers who need an accurate chemical dosing system that works right out of the box. Our EZO™ pumps have all the functions of a medical-grade IV pump combined with the bulk dosing requirements of an industrial chemical pump. Just tell it what you want to do, and it takes care of the rest.
