1. A pump, comprising:
a pump rotor, the pump rotor including at least one indentation and at least one protrusion extending radially outward from the pump rotor beyond the at least one indentation; and
a plurality of balls displaced by the pump rotor, the plurality of balls configured to displace a fluid in the pump;
wherein the pump contains no linkage members and no piston other than the plurality of balls; and
wherein the pump rotor pushes the plurality of balls outwardly from a center of the pump, the at least one indentation and the at least one protrusion of the pump rotor successively engaging one or more balls of the plurality of balls during rotation of the pump rotor, the one or more balls of the plurality of balls being disposed radially outward from the center of the pump by a first distance when the at least one indentation engages the one or more balls of the plurality of balls, the one or more balls of the plurality of balls being disposed radially outward from the center of the pump by a second distance when the at least one protrusion engages the one or more balls of the plurality of balls, and the second distance being greater than the first distance.
