API Plan 13 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.
- Removes heat and flushes particulate from the seal chamber
- Allows the seal chamber to be self-venting when used with horizontal pumps
See page 11 of the Mechanical Seal Support Systems Applications Guide for additional details.
