ABSTRACT:
A peristaltic pump having a single pumping roller mounted on an eccentric portion of a drive shaft for compression of an elastomeric tube wrapped at least one revolution therearound. The peripheral surface of the roller around which the tube is disposed comprises a frusto-conical surface. A tube compressor includes a central bore having a frusto-conical surface coaxial with the drive shaft and corresponding to the surface of the roller. Means are provided for selectively adjusting the axial position of the tube compressor to either increase or decrease the degree to which the tube is compressed upon rotation of the roller, thereby providing selective control of the output pressure of the pump. The output of the pump may be selectively varied by variation of the speed of the drive shaft.
