Claim 5:
6. A pump rotor assembly comprising:
a hub configured to couple with a drive shaft of a pump, the hub comprising at least a first hub interface surface that extends longitudinally in a direction parallel to a hub rotation direction along the hub and an axial face that is transverse to the hub rotation direction;
a first roller assembly comprising a first support frame, a first axle and a first roller, the first roller assembly further comprising a first roller assembly interface surface configured to permit the first roller assembly to slide longitudinally in the direction parallel to the hub rotation direction along the first hub interface surface, through the interaction of the first hub interface surface and the first roller assembly interface surface to seat the first roller assembly onto the hub; and
a collar configured to couple with the hub, so that the collar engages the axial face of the hub, wherein the collar is selectably movable between (1) a first position wherein the collar is engaged with the axial face of the hub and the collar permits the first roller assembly to be removed from the first hub interface surface by moving towards the axial face and (2) a second position wherein the collar is engaged with the axial face of the hub and the collar blocks the first roller assembly from separating from the first hub interface surface.
