ABSTRACT:
A fluid separator device allows for introducing air entrained in a liquid flow to a centrifugal pump in a manner that will not allow the pump to become gas bound. One example device designed according to this invention includes a housing having an inlet and an outlet downstream of the inlet. An air chamber is positioned on an opposite side of the inlet from the outlet. An air flow passage allows air from the air chamber to be introduced near a rotor assembly input of a centrifugal pump such that relatively small air bubbles are introduced to the liquid flow through the rotor assembly in a manner that prevents the air bubbles from recollecting into a larger bubble that would otherwise interfere with the centrifugal pump operation.
