Steel Waterjet S-3

Low and high speed performance in the same package

At the heart of the waterjet is the fully stainless steel mixed flow pump. There are different impellers depending on application. Efficiency has been achieved by using the latest computational fluid dynamics (CFD) techniques combined with extensive testing in the cavitation tunnels at the Kongsberg Maritime Hydrodynamics Research Centre. The S-3 steel series waterjets can be individually optimised and selected based on boat design requirements and operational profile.

Heavy duty stainless steel pump unit

The S-3 steel series is as always equipped with a duplex stainless steel pump unit providing the best possible durability under any circumstances. Best in class components are used, providing long life and reliable service. These are enabling up to 25,000 h or 5 year time service/replacement of wear parts.

Bollard pull capability closing the gap to conventional propulsors

Kongsberg Maritime Kamewa waterjets have an optimized inlet duct design as standard, providing extremely good low and mid speed performance. In practice this means increased bollard pull thrust comparable to conventional propulsors. High speed inlets are available for speeds exceeding 45 knots.

Stand alone installation with inlet drawing

Available from size 56 to 200. Waterjets are supplied with drawings of hydrodynamic design of inlet ducts. This enables optimal performance and hull stiffness when building in FRP.

Remote control systems

Kongsberg Maritime can supply a number of different control systems for waterjets, ranging from rugged, standardised systems and up to multi station, custom design systems.
