Abstract
A piston assembly for a reciprocating pump comprises a piston disposed within a liner, a flange extending radially outward from the liner, and a hollow cylindrical end part insertable into a bore in a fluid end of the reciprocating pump. A groove is formed about a circumference of an outer surface of the hollow cylindrical end part and is positioned to face a cylindrical, inner side wall of the bore in the fluid end when the end part is inserted into the bore. A seal element is seated in the groove and is configured to protrude radially outward therefrom. The seal element includes a sealing surface oriented generally parallel to a longitudinal axis of the hollow cylindrical liner to form a seal between the end part of the piston assembly and the cylindrical, inner side wall of the bore when the end part is inserted into the bore.
