Stuffing box seal assembly
In accordance with illustrative embodiments of the present invention, the arrangement of a combination stuffing box and pressure transmitter system for use with a reciprocating or rotating rod on pumps or pumping systems is disclosed. The stuffing box assembly includes a housing that holds a primary and second seal that are separated by a lubricating reservoir filled with a refined environmentally friendly sacrificial lubricant from the unknown fluid being pumped. The secondary seal transmits the pressure of the fluid being pumped to the sacrificial lubricant that is being sealed from the atmosphere by the primary seal. The secondary seal has its outside diameter sealing against the housing liner and has its inside diameter sealing on the pump rod. It is free to move with respect to the liner and the rod to transmit the pressure of the fluid being pumped to the sacrificial lubricant between the primary and secondary seals, as well as balance the pressure across the secondary seal. By design, any unbalance of pressure across the secondary seal will always be in the direction of the fluid being pumped. The primary seal operates under optimum conditions to prevent leakage of the refined safe lubricant, having known characteristics, to the environment.
