Plan 14 in Sealban

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.

This plan:

 Removes heat and flushes particulate from the seal chamber

Controls seal chamber pressure on vertical pumps

Plan 14 is available as a kit of components ready for field assembly.
