Abstract
A dual priming system connected with a centrifugal pump to evacuate gas therefrom includes a positive displacement pump fluidly connectable with the centrifugal pump and a venturi fluidly connectable with the centrifugal pump in parallel with the positive displacement pump. The dual priming system is operational in a first mode, wherein the positive displacement pump is inactive and the venturi is activated, and a second mode, wherein the positive displacement pump is activated and the venturi is activated.
