Abstract: A peristaltic pump that reduces electrical current flowing through a pumping tube segment includes a central rotor mounted on a central rotation axis, a shoe with a curved surface facing toward the central rotor, multiple rollers mounted along the circumference of the central rotor and the pumping tube segment positioned between the curved surface and the central rotor. Each roller of the plurality of rollers is a member of a roller group, each roller group includes at least two rollers, rollers in a particular roller group are physically located closer to each other than to rollers in other roller groups, and at least two rollers pinch a portion of the pumping tube segment against the curved surface through a full rotation of the central rotor.
