Abstract
A packing assembly provides a seal for an annular space between a pump plunger and a pump body of a reciprocating plunger pump. The pumping assembly includes an elastomeric header ring disposed in a high pressure end of the annular space for preventing migration of fluid through the annular space due to radial compression of the header ring. At least one V-shaped packing ring is disposed in the annular space behind the header ring and has a concave side thereof facing the header ring. A female adapter ring is disposed in the annular space behind a last V-shaped packer ring. A V-shaped anti-extrusion ring is disposed in the annular space between the last V-shaped packing ring and the female adapter for preventing extrusion of the last V-shaped packing ring between the female adapter and each of the pump plunger and the pump body. The present invention relates generally to packings for use in an annular packing space between a first cylindrical member which reciprocates within a cylindrical bore of a second member, and more particularly, but not by way of limitation, to such packing sets specifically designed for use in sealing the high pressure ends of a reciprocating plunger pump u…
