Seeking help with double-end face mechanical seal issues
Thread Content
For PLAN53 flushing systems using volatile hydrocarbons with a density of C5 or lower as the medium, can a combination of cemented carbide and cemented carbide be used as the material for the friction pairs of the stationary and rotating rings in the mechanical seal on the medium side? Are there any relevant specifications or standard requirements?
No, refer to API 682-2014 for shaft seal systems for centrifugal pumps and rotor pumps.
Hard-to-hard mechanical seals are not recommended; soft-to-hard seals are more suitable~
