TLDR
A peristaltic pump as mentioned in this paper is a rotatable drum having rollers 5 or cams 5' for squashing a flexible tube against a profiled surface 10 of a presser plate 7.Abstract:
A peristaltic pump comprises a rotatable drum 2 having rollers 5 or cams 5' for squashing a flexible tube 9 against a profiled surface 10 of a presser plate 7. Tube 9 is mounted between supports 14 and 15 on presser plate 7 and is automatically movable between an inoperative and operative (pumping) position by pivotal movement of plate 7 about axis 8 produced by an electro mechanical actuator. A flexible membrane 33 is sandwiched between rollers 5 or cams 5' for eliminating shear forces on the tube 9. The construction of the pump and shape of profile 10 are such as to mimimise pulsations in the output flow. Systems for supplying a sample for analysis to spectroscopic apparatus using the peristaltic pump are also described.read more

Reduced pulsation tapered ramp pump head
TL;DR: In this paper, a peristaltic pump includes a plurality of rollers for compressing and sealing a collapsible and resilient tube, and a housing and a pump arm with a specific arcuate surface and position with respect to the housing enable the successive contact and gradual compression of the rollers with the tube in a manner for moving a fluid through the tube without creating substantial fluid back pressure in an opposite direction.
