Abstract

A suction port and check valve assembly for use with a pump head. The assembly comprises a port body and a check valve. The port body may have an inlet side, an outlet side, and a top, and may comprise a horizontal bore extending from the inlet side to the outlet side and a vertical bore extending from the top to the horizontal bore. The check valve may comprise a valve seat, where the valve seat rests atop the port body with only a gasket therebetween, and a valve body atop the valve seat. The port body may attach to the pump head via alignment spacers, such as springs, minimizing misalignment and resulting leaks.
