Abstract

A stuffing box includes a housing and an internal sleeve positioned within the housing. Bearings are positioned in an annular space between the internal sleeve and the housing, such that the internal sleeve is journalled for rotation within the housing. Static seals are positioned within the internal sleeve to engage a rod. A mechanical seal is disposed in the annular space between the internal sleeve and the housing to block the passage of produced well fluids into the bearings.
The mechanical seal has a first body with a first sealing surface secured to and rotating with the internal sleeve and a second body with a second sealing surface secured to and remaining stationary with the housing. Biasing springs are provided to maintain the first sealing surface and the second sealing surface in sealing engagement.
