To test the pump an inlet container filled with water was added below the height of the pump and the inlet tube of the pump was submerged in the water. An empty outlet container was placed above the height of the pump and the outlet tube of the pump was inserted into the outlet container. To actuate the pump, the plunger of the syringe was retracted, sucking in air to the barrel and deflating the actuator pockets. This created a vacuum in the pump that pulled water from the inlet container through the inlet valve into the pump. Water was pulled into the pump despite not priming the pump with water beforehand and having air in the line. The plunger was then advanced, pushing air into the pockets of the actuator, inflating them. The inflated pockets displaced the fluid in the chamber analogous to muscle contraction in the heart, pumping fluid out of the pump through the outlet valve into the outlet container. The one-way inlet and outlet valves prevent fluid from moving from the outlet to the inlet, directing flow only from the inlet to the outlet.
