Abstract
A fluid cylinder for a fluid end section of a reciprocating pump includes a body having a pressure chamber and a plunger bore that fluidly communicates with the pressure chamber. The plunger bore includes a packing segment configured to hold packing. The fluid cylinder includes a sleeve received within the packing segment of the plunger bore. The sleeve is configured to hold a plunger within an internal passage of the sleeve such that the plunger is configured to reciprocate within the plunger bore during operation of the reciprocating pump. The fluid cylinder includes a retention mechanism secured within the plunger bore such that the retention mechanism is configured to retain the sleeve within the packing segment of the plunger bore.
