The present invention relates to a pump utilizing multiple tubes that are arranged helically and with the ends of the tubes oriented axially and not tangential to the drive shaft. Operation of the pump is achieved by rotation of the drive shaft. Rollers are positioned on the shaft such that the compressible tubes are compressed to the point where fluid cannot move within the tubes past the line of compression. The lines of compression move along the tubes by rotation of the shaft. Due to the helical arrangement of the tubes the lines of compression also move axially along the shaft. The fluid enters the tubes at the entrance portion of the tubes and is forced through the tubes due to the moving lines of compression and finally exit the tubes at the exit portion of the tubes. Continued rotation of the shaft causes continuous pumping of the fluid. This results in a very economical and compact pump for use in confined spaces or requiring axial flow. The multiple tubes also provide for a high rate of flow.
