Kumera - Angle Gearboxes

Bevel gearboxes can be used for a range of different applications, and traditionally most bevel gearboxes delivered by Kumera have been utilized for bow thruster applications.

Another typical application for Kumera gearboxes has been fire pump drives for offshore firefighting system, requiring high water volumes and securing trouble free operation in case of a fire.

Kumera has also developed and delivered bevel gearboxes for main propulsion purposes, e.g. for a series of SWATH vessels, and more traditional displacement vessels.
