Abstract
A peristaltic pump comprising a race having an internal surface for supporting a flexible tube in a tube pumping region, and a rotor rotatably mounted about a rotor axis and carrying rollers that travel in a circular path adjacent to the tube pumping region, the rollers having a large diameter central portion between smaller diameter portions to cause the tube to be self-aligning at the central portion. Also disclosed are a cover mounted on the race for movement in a direction parallel to the rotation axis between a loading position spaced from the race sufficiently to permit insertion of the tube through a tube insertion opening into a tube mounting region and an operational position in which the tube insertion opening is closed; and self-loading a tube into a peristaltic pump via rollers having a small diameter end portion and an adjacent larger diameter portion.
