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. The apparatus also includes a plurality of drums deformable between expanded and contracted conditions, conduits connecting the drums with the tops of the compartments, and a motion transmitting arrangement pivotally connected to the drums for repetitively rotatably moving through a rotation cycle to cause deformation of the drums between expanded and contracted conditions for producing vacuum and positive pressurized conditions at separate times in each of the compartments to cause entry of the flow of the fluid mixture into the compartments from the intake chamber via the intake valves in response to producing the vacuum condition therein and exit of the flow of the fluid mixture from the compartments to the discharge area via the outlet valves in response to producing the positive pressurized condition therein.
