The pump's functionality is based on peristalsis, a mechanism employed by the human digestive system. This involves the rhythmic contraction and relaxation of a muscular structure surrounding a tube, resulting in the movement of its contents.
The pump itself utilizes an elastomer tube that is compressed repeatedly along its entire length by rollers. During the interval between successive passes of the propelling roller, the tube returns to its original diameter, generating a vacuum that draws in the product for transfer.
