PUMP MAINTENANCE
Seal Wear-In Procedure
Recommended after replacing
standard seals only (5063-6589)
Important: Do not perform this procedure
when installing normal phase seals
(0905-1420).
It will cause severe
d
amage to the seals.
1. Fill the bottle with 100 ml of isopropanol,
and place it in the solvent cabinet. Then,
place the new pump head’s tubing
(
including bottle head assembly)
into the bottle.
2. Screw the adapter to the Active Inlet
Valve. Connect the inlet tube from the
bottle head directly to the adapter.
(
quat pumps and binary pumps with
selection valves only)
3. Connect the restriction capillary to the
purge valve. Insert the other end of the
capillary into a waste container.
4. Open the purge valve and purge the
system for 5 minutes with isopropanol
at a flow rate of 2 ml/min.
5. Close the purge valve and set the flow
to a rate that is adequate to achieve a
pressure of 350 bar. Pump for 15 minutes
a
t this pressure to wear in the seals.
You can monitor the pressure at your
analog output signal using the handheld
controller, ChemStation or any other
controlling device connected
to your pump.
6. Turn OFF the pump flow and slowly open
the purge valve to release pressure from
the system.
7. Disconnect the restriction capillary and
reconnect the outlet capillary to the
purge valve. Reconnect the appropriate
tubing to the Active Inlet Valve.
8. Rinse your system with the solvent that
you plan to use for your next application.
