<p>A stuffing box for a high-pressure, reciprocating pump. A high pressure reciprocating pump has a mounting plate secured: to the plunger end of a pump drive housing and a suction and discharge manifold hingedly connected thereto. A stuffing box in an opening in the mounting plate has a central bore receiving one end of the plunger and forming a plunger pressure chamber coaxial with the plunger. A tapered packing assembly in the stuffing box surrounds the plunger in sealing relation. A suction and discharge valve cartridge in a valve cavity in the manifold block is coaxial with the plunger. The stuffing box includes a body and a sleeve. The body includes a longitudinal socket having an inner surface with a taper extending longitudinally a predetermined distance. The sleeve is disposed in the socket of the body. The sleeve includes a bore longitudinally disposed therein configured to receive a plunger of the pump. The sleeve has an outer surface tapered such that the outer surface of the sleeve substantially corresponds to the inner surface of the body. The body compressively retains the sleeve.</p> |
