Abstract
A peristaltic pump includes a panel member having a rotatably driven rotor with roller elements on it, two projections which each have insert-receiving slots, two cover-supporting slots each extending away from a respective projection, and an orientation tab disposed between the projections. A one-piece insert has a platelike portion with ends slidably received in the insert-receiving slots, a recess which receives the orientation tab, and two pairs of aligned projections on opposite sides thereof, the insert further including a flexible tube extending around the rotor and having its ends engaging respective projections on one side of the platelike portion. A cover member is removably supported on the panel member by flanges which slidably engage the cover-receiving slots and by locking surfaces thereon which engage locking surfaces on the projections, the cover member including a curved surface adjacent and facing the roller elements on the rotor, and serving as a cover for the tube and rotor.
