Plan 65 - Single seals - External leakage detection reservoir

Features

Description: Plan 65 is a liquid leakage detection plan normally used for single seals. It utilizes a level switch on a reservoir to set off an alarm when excess leakage is detected.

Advantages: Provides an alarmed indication of excessive seal leakage that can shutdown equipment if necessary.

General: The system includes a loop to by-pass the orifice to prevent high pressure on the atmospheric side of the seal. The gland throttle bushing design should be consistent with the fluid’s properties. Gland throttle bushing designs can vary from fixed designs to segmented bushings.
