Kongsberg Steel Waterjet S-3

The Kamewa S3 is developed for the largest and most demanding applications. The waterjets are equipped with a mixed-flow pump for maximum efficiency. To facilitate the hydrodynamic performance of the pump the built-in bearings keep the impeller in correct position and provide control of the important tip-clearance. The outboard bearing position also simplifies the overall load distribution in the aft ship and leads to efficient use of the inlet duct as load carrying structure.
