    Abstract: A seal system for an oil well head, wherein the shaft rotates about its axis to drive a progressive cavity type pump. Primary and secondary polytetrafluoroethylene seals surround a sleeve that encircles the shaft. Pressure detectors connect to the space between the seals to detect leaks past the primary seal and signal a remote repair facility. The secondary seal assumes the sealing function while repairs are scheduled.
