Plan 65B

Description: Plan 65B is a TOTAL liquid leakage detection

system measuring accumulated liquid leakage. Normally for

Arrangement 1 single seals. Seal leakage will collect in a

containment vessel with a level

transmitter and bypass line to

prevent pressure build up. This

plan will require that the operator

periodically drain the collection

vessel to allow for continuous

operation. Use with closeclearance

gland throttle bushing.

Objective: Safely detect seal

failure and allow for shutting

down the pump and containing
