ABSTRACT:
The rollers of a peristaltic pump are provided with an unyielding surface, so as to insure uniform compression of the pumped tube. The rollers are mounted on their driving axles by means including yielding rubber bushings, whereby the rollers accommodate to varying diameters of pump tubing and do so without generating objectionable noise. Because the rollers yieldingly ride over the irregularities, two adjacent tubes of slightly differing diameters can simultaneously be contacted and stripped by one set of rollers.
