Abstract:
1. A peristaltic pump, comprised of at least one of a flexible resilient tube and hose occluded between and formed over staggered opposed curved surfaces in a traveling wave pattern to move a flow-able material through said at least one transfer tube such that two occlusions occur on each curved surface at points of tangent between said curved surfaces along said at least one transfer tube, wherein said at least one transfer tube is occluded, comprising: a pump frame; a platen operatively associated with said pump frame, the platen having a series of curved surfaces, and where each curved surface extends out from the platen and is perpendicular to the flow of the pump; a pressure assembly including a plurality of curved surfaces operatively disposed to said curved surfaces of said platen and generally perpendicular to the direction of flow through the pump, each of said pressure assembly curved surfaces centered on a space between two curved surfaces of said platen; said at least one transfer tube sandwiched between the platen and said pressure assembly in the direction of flow; a drive assembly operatively associated with said pump frame for driving at least one of said platen and said pressure assembly in a wave sequence so as to sequentially occlude portions of said at least one transfer tube corresponding to the adjacent center between the curved surfaces on the platen and pressure assembly to promote a peristaltic pumping action in said at least one transfer tube.
