| Bearing lubrication | per the manufacturer's interval, typically annually |
|---|---|
| Mechanical seal inspection | annually or on leakage |
| Strainer cleaning | weekly to monthly depending on water quality |
| Wear ring/clearance check | at overhaul, typically every 4-6 years |
| Coupling alignment check | annually or after disturbance |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Impeller/wear ring clearance | typically increases several-fold from new-build clearance before capacity loss becomes significant for this pump class - confirm the specific figures in the ALP-series manual rather than a generic value |
|---|---|
| Bearing vibration trend | assess against the vessel's own baseline reading; a sustained rise is more meaningful than any single absolute figure |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
If serving an essential cooling system, class will expect this pump (and any standby unit) to be on the PMS with completed maintenance history, and to demonstrate correct auto-start/changeover if configured as a standby pump.
Estimated lifetime: Seawater-duty centrifugal pumps of this size commonly reach on the order of 20,000-30,000+ running hours between major overhauls when maintained correctly - actual life depends heavily on water quality, cavitation avoidance, and seal care.
