ABSTRACT:
A check ball valve seat assembly for a diaphragm pump is provided that includes an annular carrier plate which accommodates an annular seat member. The assembly is sandwiched between two components of a diaphragm pump, such as a component for providing a retainer for the ball component of the check valve and a retainer providing a backing support for the check ball valve seat assembly. The annular seat member sealingly engages the ball retainer component and the support component of the pump which prevents the fluid that is being pumped from coming into contact with the annular carrier plate.
