PD 76

Leakage Detection

Used to detect and monitor leakage of the inboard seal, these seal support systems can detect liquid leakage (API Plans 65 and 75) or gas leakage (API Plan 76), or a mixture of gas and liquid leakage (API Plan 75). A PD 76 (API Plan 76) system diverts non-condensing inner seal leakage from a dual unpressurized seal where the outer seal is dry running, to a flare or vapor recovery system.

PD 76


  • Can be used to test the inner seal while the pump is operating.
  • A PG 72 (API Plan 72) system can be used in conjunction with PD 76 to ensure fugitive emissions are not released to the environment.
