Where bulkhead openings for shafts are required to be watertight to protect adjoining spaces against flooding, the Centrax bulkhead seal offers the optimum solution.

In an axially split housing made of aluminium which is mounted on the bulkhead opening are two segmented carbon rings which run directly on the shaft.

Two garter springs and a sectioned thrust ring ensure proper contact of the sealing faces on the shaft and on the housing sides.

Radial and axial shaft movements are taken up by the Centrax bulkhead seal without any problem. There is practically no wear owing the the very good self-lubricating property of the carbon rings. Aside from standard design shown here there are special designs with greater radial and/or angular movement available.

The Centrax bulkhead seal is a well proven product, in service with merchant and naval shipping.

If a gas-tight and water-tight seal is required we can offer our Simplex-Compact bulkhead seal.

The design is based on forward Simplex-Compact seal. However, the two sealing rings face each other, thus acting as a barrier chamber which is filled with oil.

This chamber is connected to a 4l oil tank and by means of the circulator a permanent lubrication and cooling is provided. This seal can also be supplied completely radially and axially split.

For this seal to recess, pitch circle and outer diameters can be adapted to the dimensions required to pass shaft flanges, coupling, bearings etc. through the bulk head.
