API 682 PLAN 65A

API 682 Plan 65A is used as a seal leakage detection system for a single mechanical seal with either an outboard segmental bushing or containment seal. This system is actuated by high flowing leakage levels entering the reservoir and should only be used on condensing fluids.

When the primary inboard mechanical seal fails, high flowing leakage enters the reservoir of the Plan 65A. This will actuate a level transmitter at a desired set point. Over flow from the reservoir is diverted to the facilities drainage collection system. This system is ideal for seals which have the tendency to weep during regular operation because level actuation only occurs in high flow situations.
