Supreme® Bulkhead

SUPREME® BULKHEAD

In the event of a major water leak, safety on board should always be a priority. The Supreme Bulkhead seal is generally used to prevent flooding of the bulkhead seal’s adjacent compartments in the unlikely event of an accident.

Type of vessel(s)

Seagoing vessels
Inland vessels

Advantages

Seals off non-flooded compartments if flooding occurs
Ensures a safe return to port
Allows large radial (4 mm) and axial (30 mm) play
Can be used for low- and high-speed shafts
Gas-tight bulkhead seals on request.

HOW IT WORKS

During shaft operation the lip seals will be lifted from the inside face of the aluminum housing, because of the circumferential force, being free from wear. To ensure proper lubrication at start-up and slower speeds, the seals are pre-lubricated with silicon spray.

In the 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 can handle up to 2.0 bar draught water pressure. The Supreme Bulkhead seal is available for shaft diameters from 110 to 710 millimetres.

OPTIONS

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.
