4.6.3 Double mechanical seal - tandem
arrangement
Flushing liquid
In order to continue functioning, the mechanical seals require
a flushing liquid, some of its purposes being:
•
Preventing leaks
•
Dry-run protection
•
Lubrication and cooling of the mechanical seals
•
cutting off the air from substances which react unfavoura-
bly with oxygen.
A pure liquid, compatible with the pumped liquid, serves as a
flushing liquid.
Ensure the functioning in this way:
1. Open feed line for flushing liquid
2. Bleed seal cartridge
3. Ensure unpressurized circulation.
A pure liquid, compatible with the pumped liquid, serves as a
flushing liquid.
In case of abrasive media provide a „lost“ flushing, i.e. where
the flushing liquid is discharged directly.
