The following pages describe maintenance (simple repairs) of the pump that can be carried out without opening the main cover.
Procedure | Typical Frequency | Notes |
|---|---|---|
|
If solvent filter is blocked |
Gradient performance problems, intermittent pressure fluctuations | |
|
If internally leaking |
Pressure ripple unstable, run Leak Rate Test for verification | |
|
If internally leaking |
Pressure ripple unstable, run Leak Rate Test for verification | |
|
If internally leaking |
Pressure ripple unstable, run Leak Rate Test for verification | |
|
If internally leaking |
Solvent dripping out of waste outlet when valve closed | |
|
If the frit shows indication of contamination or blockage |
A pressure drop of > 10 bar across the frit (at a water flow of 5 mL/min with open purge valve) indicates blockage | |
|
If pump performance indicates seal wear |
Leaks at lower pump head side, unstable retention times, pressure ripple unstable - run Leak Rate Test for verification | |
|
Exchange pistons, see シールウォッシュの無いポンプヘッドのメンテナンス |
If scratched |
Seal life time shorter than usual - check pistons while changing the seals |
