A peristaltic pump is a type of pump used to move fluids through a flexible tube by cyclically compressing and releasing the tube with a set of rollers. As the rollers squeeze the tube, they push the fluid forward in one direction. Because the fluid remains inside the tube and never comes into contact with the pump mechanism, peristaltic pumps are ideal for applications requiring high levels of cleanliness or for handling corrosive, sensitive, or contaminating fluids. They are commonly used in industries such as pharmaceuticals, medical devices (e.g., dialysis machines), laboratories, and food processing, where controlled flow and contamination prevention are crucial.
