API Plan 65

Leakage from seal faces is collected via the drain port & directed to a liquid collection system via a vessel equipped with a high-level alarm.  


  1. The quench fluid acts as barrier in between atmosphere and process fluid.
  2. The quench fluid reduces oxidation and coking of product & also cools seal faces.
  3. Flushes away undesirable material build up under seal faces.        
  4. Can be used with water, steam or an inert gas.
  1. In services where seal leakage is condensing.
  2. Used for single seals. Caution  
  3. Vent connection should always be plugged.  
  4. Orifice downstream of the level switch should be located in vertical piping leg to avoid accumulation of fluid in drain piping.
  5. Shut down the pump as soon as high-level alarm is activated & attend the seal.
