NOTE It is especially important to regularly replace end-line
filters when using aqueous eluents, which may
contaminate the filter with bacteria or algae. The
bacterial buildup may not be visible.
•
Blockages in inlet tubing
Kinked or clogged tubing causes the pump to be “starved” for eluent. Replace
the tubing and fittings (see
Section 5.3 ).
•
Dirty check valve
Clean or replace the pump check valve (see Section 5.5 ).
•
Liquid leaks at junction between pump head and pump casting
Use the open-end wrench (P/N 014605) provided in the ICS-2000 Ship Kit
(P/N 057905) to tighten the two acorn nuts that attach the pump head to the
pump housing (see
Figure 5-11 ). Tighten the nuts evenly (12 in-lb torque).
If the leak persists, replace the piston seal (see Section 5.6 ).
•
Liquid leaks from the seal wash port
Replace the piston seal (see Section 5.6 ).
•
Scratched pump piston
Check the pump pistons for scratches and replace if necessary (see
Section 5.7 ).
