PUMP MAINTENANCE
Purge Valve – Exchanging the PTFE Frit 1100 standard pump modules
Purge valves feature a gold seal held in
p
lace with a plastic cap. Small leaks can
occur here, so you will need to replace the
gold seal after the valves have been
removed more than once or twice.
When replacing the frit, make sure that
t
he cutout side faces up, which provides
more surface area on the side facing the
solvent flow.
1. Remove capillary and waste tube.
2. Use a 14 mm wrench to
unscrew the valve.
3. Remove the plastic cap and
the gold seal.
4. Use tweezers to remove the old frit
and install a new frit.
5. Replace the gold seal and
the plastic cap.
6. Install the valve.
