How Does a Tubing Pump Work?
pump head animationThe pump consists of only 2 parts, the rotor and the housing. The tubing is loaded between the rotor and the housing where it is squeezed (occluded).

The rollers of the rotor move across the tubing pushing the fluid or gas.  The tubing behind the rollers recovers it shape, creates a vacuum and draws fluid in behind it.

A "pillow" of fluid is formed between the rollers. This volume is specific to the pump design and tubing size. Flow rate is determined by the speed of the pump and the volume of the pillow.
