Abstract

A stuffing box assembly (4) comprising a primary housing (8) having a longitudinally oriented hollow bore (11) extending therethrough, a hanger assembly ( 9 ) within the longitudinally oriented hollow bore of the primary housing, and drive means (10) received within the hollow bore of the hanger assembly. The hanger assembly has a longitudinally oriented hollow bore extending therethrough. The drive means has means (15) to releasably secure the drive means to a pump rod such that the pump rod is hung from and supported within the primary housing by the hanger assembly. Rotation of the drive means causes a corresponding rotation of the pump rod. The hanger assembly includes one or more seals (17) to contain well fluids and to help prevent the flow of well fluids into the bore of the hanger assembly.
