API Plan 14 Flush, Combination of Plans 11 and 13

API Plan 14 combines Plan 11 and Plan 13. Flow is recirculated from the pump discharge into the seal chamber and from the seal chamber to the pump suction. Fluid flow is increased since the seal chamber is continuously vented, leading to higher cooling capacity.

plan 14 


  • Removes heat and flushes particulate from the seal chamber
  • Controls seal chamber pressure on vertical pumps

See page 13 of the Mechanical Seal Support Systems Applications Guide for additional details.
