1. A pump system including an outflow pump, the pump system comprising:
a stationary housing defining an internal volume and a front face outside the internal volume extending in a first direction and a second direction transverse to the first direction;
the stationary housing including at least one tube support outside the internal volume extending outwardly from the front face for aligning and supporting a first tube and a second tube;
at least one pinch member being movable relative to the at least one tube support;
a power actuator comprising a first solenoid core and a second solenoid core of a solenoid assembly radially separated from one another and disposed in the internal volume and operably coupled to the at least one pinch member, the power actuator being movable along a longitudinal central axis;
a first shaft half coupled to the power actuator by a first bracket half extending from a first core axis toward the longitudinal central axis, the first core axis extending in parallel to the longitudinal central axis;
a second shaft half coupled to the power actuator by a second bracket half extending from a second core axis toward the longitudinal central axis, the second core axis extending in parallel to the longitudinal central axis and spaced from the first core axis; and
the power actuator configured to have three orientations that define:
a first arrangement of the at least one pinch member relative to the at least one tube support configured to pinch closed the first tube,
a second arrangement of the at least one pinch member relative to the at least one tube support configured to pinch closed the second tube, and
a third arrangement of the at least one pinch member relative to the at least one tube support configured to pinch closed neither the first tube nor the second tube.
