A peristaltic pump having a housing which is formed with an annular recess which has an arcuate cross-sectional configuration, is provided with a conduit extending within the recess. The conduit has a back wall shaped to conform to the cross-sectional configuration of the recess and a flexible front wall extending transversely between opposite side edges of the back wall. Slide flanges are provided at each side edge of the front and side walls and are secured with respect to the housing to secure the conduit with respect to the housing and to hold the flanges taut. A pumping member is provided which has a rotor mounted for rotation and a plurality of rollers mounted on the rotor. The rollers each have a profile adapted to mate with the arcuate cross-sectional configuration of the recess and the pumping member is mounted with the rollers extending into the recess to an extent sufficient to compress the conduits to form transversely extending nips in each conduit. A drive motor is provided for rotatably driving the rotor.
