Plan 13 in Sealban

Flush from Chamber to Suction

API Plan 13 recirculates flow from the seal chamber to the suction side of the pump. This plan is common for vertical pumps.

This plan:

 Removes heat and flushes particulate from the seal chamber

Allows the seal chamber to be self-venting when used with horizontal pumps

Plan 13 is available as a kit of components ready for field assembly.
