To reduce leakage in a mechanical seal, a blocking agent may be introduced, the seal ring may be attached to a gasket, the seal ring may be integrally formed with the gasket, and/or the seal may be provided with an access window to allow adjustment of the seal ring, seal ring joint, gasket, and/or seal ring-gasket mating surface without removing the seal from the shaft. The blocking agent may be introduced into a fluid contacting a mechanical split seal or is present in the seal in tablet form and released by contact of the tablet with the fluid. The blocking agent migrates through the seal and lodges inside or plugs leakage paths such as the mating points of the split surfaces of the seal face segments, and the joints of the seal rings and gaskets, reducing further fluid leakage therethrough. |
