According to Eagle Burgmann, "A high-point vent must be provided in the vertical pump seal chamber (or seal gland) to ensure that seal faces never see vapors."

Suspect this high point from the seal chamber is to allow of escape of flash vapor produced in the sealing liquid as a result of the heat generated at the seal faces. This would be valid for process liquids with bubble point temp lower than say 15-20degC above the max operating temp of the process liquid at minimum normal operating suction pressure.
