    Formerly known as DSS (Deep Sea Seals) Manejet PSE, Composite PSE and EXJ, the Wärtsilä Jetguard range is specifically developed for demanding operating conditions, such as the high speeds and varying pressures typically seen on waterjets. It is available as both commercial and military (shock capable) options.

    Partially and fully split options are available to enable maintenance and seal replacement without removing the shaft. Maintenance can also be done afloat through the use of an inflatable seal.

    WFS1R-P-J & WFS1R-P-LJ, main components of the commercial types manufactured from bronze. Corrosion free composite materials are also available for easy maintenance and reduced weight.

    WFS1R-P-M & WFS1R-F-M, military type, largely of aluminium and bronze construction with 00 pressurized interfaces.
