Main Cooling Seawater Pump (Centrifugal) · Pumps
The LKH Evap is a low NPSHr, high efficiency centrifugal pump is optimised for evaporation application.
| Mechanical seal inspection | typically every 4000-8000 hours or condition-based on leakage |
|---|---|
| Bearing lubrication/renewal | per the maker's schedule for the specific motor/bearing housing fitted |
| Impeller and wear part inspection | typically at each seal service or annually |
| O-ring/gasket renewal | at each disassembly for seal or impeller service |
Where this pump serves the fresh water generator/evaporator, class and flag expect documented product water quality monitoring rather than a pump-specific survey item; the pump itself is typically covered under general auxiliary machinery maintenance records.
Estimated lifetime: Close-coupled hygienic-design centrifugal pumps of this type commonly run 10-15 years in continuous evaporator service with periodic seal and bearing renewal; a single fixed operating-hour figure is not meaningful without knowing the actual duty cycle and water quality.
