Regular maintenance is crucial to ensuring the reliable operation of your marine-rated equipment, and the Alfa Laval LKH centrifugal pump is no exception. To keep this electrically driven process/service pump running efficiently, it's important to address common issues such as mechanical seal leakage, cavitation erosion, impeller wear, and motor bearing wear. These problems can be mitigated by regularly checking for seal leaks, monitoring motor current, and inspecting for any vibration during service intervals. Additionally, the wetted parts and seals should be inspected thoroughly during planned maintenance to prevent unexpected downtime. To make these tasks easier, it is recommended to keep a stock of essential spare parts, including the mechanical seal, O-ring kit, bearings, and impeller. By following these service notes and maintaining a supply of critical components, you can extend the life of your Alfa Laval LKH pump and ensure it continues to handle clean liquids and process water effectively in marine applications.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
