What component is used to squeeze the flexible tube in a flexible tube pump?

In a flexible tube pump, the component that is used to squeeze the flexible tube is primarily a compression ring. This component is designed to apply pressure at specific points along the flexible tube, effectively creating a pumping action as it compresses the tube. When the compression ring squeezes the tube, it forces the fluid within it to move through the tubing and into the desired delivery system.

While other components like diaphragms are used in various pumping systems, and hydraulic pressure plays a role in some pump mechanisms, the compression ring is specifically configured to fulfill this squeezing action in a flexible tube pump, facilitating the movement of the fluid through the system. The oval rotor, on the other hand, is not associated with this type of pump operation.
