Abstract
Embodiments of the invention provide a pump including an inlet port, an outlet port, a pumping chamber, and a porting system. The porting system includes an inlet tube including a trap in which a first volume of fluid can be collected. The porting system includes a reservoir with a first chamber and a second chamber separated by a partial port wall. The second chamber receives fluid directed over the partial port wall from the pumping chamber. The reservoir collects a second volume of fluid substantially equal to the first volume of fluid. The first volume of fluid and second volume of fluid provide enough fluid trapped inside the pump to allow the pump to temporarily operate when substantially no fluid is flowing into the inlet port.
