ABSTRACT:
A system for maintaining a constant biasing pressure upon the sealing members of a rod pump stuffing box utilizes a hydraulic system under a constant preset pressure to bias the seal member into sealing engagement against the pump polished rod. Means are also disclosed for continuously monitoring the amount of wear undergone by the seal means and for actuating a warning light or shutting down the pumping unit when the seal means has undergone extensive wear or when leakage from the stuffing box has reached a predetermined level.
