API Plan 32 External Flush

Swagelok Alabama | Central & South Florida | West Tennessee Services Mechanical Seal Support Systems Process Side Plans (Kits & Assemblies) API Plan 32 External Flush

API Plan 32 delivers a clean flush fluid into the seal chamber from an external source. Typically used with a close-clearance throat bushing, this arrangement can be used to ensure a higher pressure in the seal chamber. Flush fluid will migrate past the bushing, so it is important to ensure the flush fluid is chemically compatible with the process fluid and that process fluid dilution is not a concern.
