Abstract
A passive sequential pump system for use in moving a fluid is provided. The system comprises a plurality of valves. Each valve of the plurality of valves is positioned adjacent to another valve of the plurality of valves. Each of the plurality of valves includes an opening and an inner surface. The inner surface is expandable towards the opening. The system also comprises a conduit defined by the opening of each of the plurality of valves. The system further comprises an air source providing air to each of the plurality of valves and a controller controlling the air source to each of the plurality of valves. The system generates peristaltic motion to move a fluid through the conduit by increasing the air in each of the plurality of valves, thereby correspondingly closing each opening in sequence, peristaltic motion is generated to move a fluid through the conduit.
