Repairing the Pump
Exchanging the Pump Seals and Seal Wear-in Procedure
Exchanging the Pump Seals and Seal
Wear-in Procedure
When required:
Seal leaking, if indicated by the results of the
leak test
Tools required:
4-mm hexagonal key, Wrench 1/4 inch
Parts required:
Seals (pack of 2) 5063-6589 (standard) or
0905-1420 (for normal phase applications)
For the seal wear-in procedure:
Adapter AIV to inlet tube (0100-1847)
Restriction capillary (5022-2159)
1 Disassemble the pump head assembly (see
Removing and Disassembling the Pump
Head Assembly on page 110).
2 Using one of the plungers carefully remove
the seal from the pump head (be careful not
to break the plunger). Remove wear
retainers, if still present.
3 Clean the pump chambers, ensure all particu-
late matter is removed. Best cleaning results
will be achieved by removing all three valves
(see pages 103, 106 and 108) and injecting
solvent into each chamber.
