ABSTRACT:
A self-loading peristaltic pump including a rotor rotatably mounted about a rotor axis, and a race having an internal surface for supporting a flexible tube in a pumping region between the rotor and the race, the surface including points that are at equal radii from the rotor axis in planes that are perpendicular to the rotor axis, the rotor including a roller for intermittently and progressively compressing the flexible tube against the race in the pumping region, the rotor including a radially extending rotor tab located outside of the pumping region for displacing the flexible tube toward the pumping region as the rotor rotates.
