Abstract

A fluid seal and retaining arrangement for securing a cylinder liner within the frame of a reciprocating piston pump. The frame and the cylinder liner cooperate to form an annular chamber within the frame about the periphery of the liner which is filled with pressurized hydraulic fluid to maintain a differential force securing the liner to the frame while providing a fluid-tight seal between the liner and the frame.
