Abstract: A pump cartridge for mounting on a drive rotor includes a roller assembly having first and second hubs maintained in a spaced apart relationship and defining an axis, and a plurality of planetary rollers arranged in a circumferentially spaced orientation about the axis, the rollers mounted to the hubs displacement radially outward. One or more compressible tubing lines are interposed between the rollers and an interior wall of the pump cartridge housing. The housing and the first and second hubs collectively define a passageway through which a spreader on the drive rotor extends and may be rotated relative to the roller assembly to displace the rollers radially outward to thereby compress the tubing lines against the interior wall. A coupling feature on the first hub engages a roller driving feature of the rotor, so that rotation of the rotor causes rotation of the roller assembly about the axis.
