Common signs of failure:

  

• Water leaking from the sea water pump body

• Corrosion or staining near pump shaft

• Pump rebuilt but shaft seal was not replaced

• Seal lip hardened, torn or distorted

• Reduced pump reliability after impeller service

• Replacement required during complete raw-water pump rebuild
