API Plan 41 Cooled Flush with Cyclone Separator
API Plan 41 is a cooled version of Plan 31. Solids are removed from the flush fluid by incorporating a cyclone separator. Flow is routed from the discharge side of the pump through the cyclone separator. Clean flush fluid leaving the separator is routed through a cooler before being returned to the seal chamber. Flush fluid containing solids is tubed back into the suction side of the pump. In order for Plan 41 to be effective, it is recommended that the specific gravity of the solids be twice the specific gravity of the flush fluid.
- Removes solids from the flush fluid
- Provides clean and cooled flush fluid to the seal chamber
