ABSTRACT:
An inherently flushing piston rod is provided for use with a reciprocating pump. A piston rod having a rod portion and a piston portion is mounted for reciprocating movement within the housing of the reciprocating pump. An axial bore is defined through the piston portion and the rod portion and fluidly connects the external environment of the rod portion to an internal chamber within the piston portion. Throughout the stroke of the piston, a flushing fluid is inherently drawn through the axial bore and into the internal chamber of the piston portion, and is subsequently delivered to a flushing space defined about the perimeter of the piston portion.
