Abstract
A pneumatic reciprocating fluid pump for pumping a fluid includes at least one check valve assembly that includes a check valve body insert, a ball within the valve body insert, and an annular sealing ring member disposed within a seat ring receptacle. The sealing ring member has dimensions smaller than corresponding dimensions of the seat ring receptacle, such that the sealing ring member is capable of moving within the seat ring receptacle. The ball is configured to slide back and forth between a first position and a second position within the check valve body insert responsive to forward and reverse flow of fluid therethrough. In one position, the ball is seated against the sealing ring member and prevents reverse flow of the fluid through the check valve assembly, and forward flow of the fluid through the check valve assembly is enabled when the ball is in another position.
