A peristaltic pump is like squeezing a hose filled with fluid to move fluid forward as the finger slides forward. The principle of peristaltic pumps is that their fingers are replaced by rollers. Fluid is pumped by alternately pushing and releasing the flexible supply hoses of the pump. Similar to pinching a hose with two fingers, when the fingers move, a negative pressure is created in the tube and the fluid flows.

A peristaltic pump is the part of the pump tube between two rollers that form a "pillow" shaped fluid. The volume of the "pillow" depends on the inner diameter of the pump tube and the shape of the rotor. The flow rate depends on the product of the speed of the pump head and the size of the "pillow" and the number of "pillows" generated per revolution of the rotor. The size of the "pillow" is generally constant (except when pumping particularly viscous fluids).
Compared to pumps with rotors of the same diameter, pumps producing larger "pillow" volumes have larger volumes of fluid supplied per revolution of the rotor, but the resulting pulsations are also greater. This is similar to the case of the membrane valve. The pump that produces the smaller "pillow" volume has a smaller volume of fluid supplied per revolution of the rotor, and furthermore, the smaller "pillows" formed quickly and continuously create a smoother fluid Provide a flow of This works the same as a gear pump.
