In which application is a peristaltic pump typically used?

A peristaltic pump is typically used in small volume applications due to its design, which allows for precise control over the flow rate, making it ideal for accurately dispensing small quantities of liquids. The mechanism works by compressing a flexible tube, which creates a vacuum that draws the liquid into the pump and then pushes it out with each rotation. This operating principle is suited for situations where maintaining the integrity of the fluid is critical, as the fluid only comes into contact with the tubing, minimizing the risk of contamination.

In contrast, applications like high volume filtration or large-scale chemical dosing generally require pumps that can handle larger flow rates and deliver significant volumes under higher pressures. Gravity-fed systems rely on gravitational force rather than mechanical pumping, making them fundamentally different from how peristaltic pumps operate. Thus, peristaltic pumps are best suited for applications where precision and minimal handling of the fluid are priorities, aligning with small volume usage.
