Abstract

A reciprocating pump includes a fluid end having a body defining a plunger bore that engages a plunger sleeve with a threaded interface, where the plunger sleeve defines throughbore configured to receive a plunger operatively reciprocating within the plunger bore during operation of the reciprocating pump. A packing assembly including a plurality of stacked annular seals is disposed between the plunger sleeve and the plunger. A packing nut having a threaded profile for engagement with a threaded surface of the plunger bore asserts a load against the packing assembly to ensure a positive engagement with the plunger.
