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.
