ABSTRACT:
A well head stuffing box leak detector and container is installable about the stuffing box of an oil well pump installation and provides for containment of any fluid leakage from worn packing or seals within the stuffing box. The device is relatively inexpensive to construct, being formed essentially of sheet and angle material. The lower seal or gasket is raised above the floor of the device, in order to prevent fluid saturation and outflow from the lower seal, and a non-concentric offset sump is also provided. The sump includes an explosion proof float assembly and switch which may be set at a predetermined position to activate an alarm and/or shut off the pump, if excessive fluid escapes from the stuffing box and collects in the sump. The device is formed in two semicylindrical halves which are hingedly connected, thus providing for easy installation about the well head T beneath the stuffing box and the polish rod extending from the top of the stuffing box.
