ABSTRACT:
A hand held an portable pump has a housing with an inlet on the bottom and an outlet on its side. A central tube extends up from the housing and has a bulb attached at its end. An inlet gate is positioned proximate the inlet to operate between a closed position in which the flow of liquid there through is inhibited and an open position in which liquid may flow through the inlet. The outlet has an outlet gate that is positioned to inhibit the flow of liquid into the housing in its closed position and to permit the flow of liquid out of the housing and into a discharge tube in the open position. The bulb is operated between an at rest position and a deflected or compressed position to urge fluid into and out of the bulb and in turn draw liquid through the inlet into the housing and to urge the liquid out of the outlet and into the discharge tube.
