ABSTRACT:
A system comprising a top mounted rotating stuffing box is provided for use with downhole pump (e.g., Progressing Cavity Pump) applications. The system also includes a split standpipe configuration that allows the stuffing box to be quickly installed or removed as needed. The split standpipe feature combined with the top-mounted aspect of the stuffing box allow for the corresponding drive units to stay intact while the stuffing box is being installed or removed.
