The cover for the damper end (K 16501) is a protective closure that shields the damper’s working face and mounting from contaminants, moisture and mechanical damage on the Sulzer ZV40/48. By keeping dirt and corrosive salts away from the damping surfaces and bearings, the cover preserves damping efficiency and extends component life. Its design also provides a secure sealing surface and mounting interface, making inspections and replacement straightforward while supporting reliable vibration control in demanding marine service.
