Fluid pump priming system

Abstract

An apparatus for priming a non self-priming fluid pump or siphon device includes three components: an outlet valve, priming pump and inlet check valve. All three components are integrated into the casting of the fluid pump or are attached separately to an already existing fluid pump or siphon device. Upon placement of the inlet check valve in a fluid, closing of the outlet valve and activation of the priming pump, positive air pressure and alternately negative air pressure are formed in the fluid pump. This action displaces air through the outlet valve and alternately draws fluid into the fluid pump from the inlet check valve. This action is repeated until the fluid pump is filled. The outlet valve is then opened and the fluid pump activated for use. The inlet check valve retains the fluid within the system regardless of whether the fluid source is depleted or the fluid pump deactivated.
