Abstract: A suction dredge pump apparatus includes a manifold having a body defining a plurality of compartments, an intake chamber disposed adjacent to the compartments along upper ends thereof, a plurality of intake valves connected to the upper ends of the compartments, and a plurality of outlet valves connected to lower ends of the compartments. The compartments have bottoms which slope downward from the upper ends to the lower ends thereof so as to produce gravity flow of a fluid mixture therethrough.
