  • Patent number: 10399090
    Abstract: An apparatus includes a manifold plate-like structure having two end regions and an opening located in the recessed region configured to allow fluid flow therethrough and a clamping device. The clamping device includes a first clamping block and a first mechanical fastener to couple the first clamping block and the manifold. The apparatus also includes a vibratory separator including a basket having support structure therein, the manifold coupled to the support structure with a clamping device. A pan is disposed above the manifold and coupled to the manifold and a screen is disposed on the pan. A pressure differential device is coupled to the manifold and configured to provide a pressure differential across the screen. A method includes coupling the manifold to the support structure, disposing the pan on the support structure, and coupling the pan to the manifold.
