Fact sheet The FF-series waterjets are as tough as jobs they were created for Robust reliability Kamewa FF-series waterjets cover the power range between 100 and 2000 kW. Typical applications include naval craft, search and rescue boats, pilot boats, work boats and pleasure boats. The FF-series waterjet units are manufactured from strong, corrosion- resistant materials. Only the impeller, shaft and steering/reversing rods are made of stainless steel. All the other components are of aluminium construction based on thorough strength calculations to minimise The inlet duct is fabricated from marine aluminium plate for light weight, optimum hydrodynamic performance and resistance The pump is a single-stage axial-flow design providing a high volume flow with good pulling thrust in a wide speed range. Usually, the FF-series jets do not require reduction gears. All FF-series waterjets can also be supplied as booster units i.e. jet units without steering components. On delivery, the Kamewa FF-series waterjets are painted and complete with structurally dimensioned inlet ducts for easy installation by bolting or welding. Rolls-Royce - the professional supplier Rolls-Royce is the world leader in research, development and manufacture of waterjets for commercial, naval and pleasure-boat markets. It is also the only supplier in the industry with its own, fully equipped hydrodynamic research centre. The centre continuously develops and tests new products and refines the existing product line. All Kamewa FF-series waterjets are produced using the latest 3D CAD/CAM tools to ensure high level of quality and accuracy in design and manufacturing. Rolls-Royce also utilises its own proprietary, computerised design program, which contains the latest waterjet technology data combined with the actual results from earlier waterjet installations. Aided by this program, individual influences and the combined effect of all the existing outlet diameters and blade pitch angles will be studied to optimise the performance of every installation. Kamewa FF-series sets new standards for small and medium-size applications of waterjets in terms of performance, Wherever you are, Rolls-Royce's global service network will be there to provide extensive through-life support for Kamewa PROFESSIONALS CHOICE

Fact sheet Max recommended displacement per waterjet unit for planing fast craft Displacement table *) The table should be used for guidance only and based on appropriate hull size and weight ratio and hull lines. Best performance will be achived by selecting a larger waterjet size for craft displacements entering into the shaded area. The waterjet unit can be installed on both displacement and planing crafts as single, twin, triple or quadruple systems. Displacement hull application require a larger jet diameter than a fast planing hull at same power. Consult Rolls-Royce in all cases for a size...
