A typical system for a simple mechanical seal is comprised of the seal, the stuffing box throat bushing, a liquid flush system, an auxiliary seal and flush, as well as barrier fluid, if necessary. Most modern pump systems are moving more towards mechanical seals as opposed to traditional pump packing and while there are many advantages to using the mechanical method, it does come with its potential failures.  ..
