Functional description
The SPX6000A4 flush unit continuously supplies flushing media from an external source to the mechanical seal. This plan is almost always used in combination with a throat bushing which serves as a throttle device to maintain a higher pressure in the stuffing box to isolate the pumped product from the seal chamber.
