- seals off non-flooded compartments if flooding occurs
- ensures a safe return to port
- allows large radial (5 mm) and axial (30 mm) play
- can be used for low- and high-speed shafts
How it works
During shaft operation the lip seals will be lifted from the inside face of the aluminium housing, because of the circumferential force, being free from wear. To ensure proper lubrication at start-up and at slower speeds, the seals are prelubricated with silicon spray.
In case of larger bulkhead passages for penetrating shaft flanges, a passage flange ring is available on which the bulkhead seal can be installed. The water-lubricated face type seals have the capacity to handle up to 2.0 bar draught water pressure. The Supreme Bulkhead seal is available for shaft diameters from 110 to 710 millimetres.

With the fully split design it is not necessary to pull the shaft during dry dock sessions. The lip seals can be bonded in situ due to the fully split design, making it easy to install and maintain. We also provide gas-tight bulkhead seals on request. Please contact us to discuss the options.
The Supreme Bulkhead seal consists of aluminium divided housing parts with Supreme lip seals that are fitted on the shaft by ball chains.
