Wärtsilä Modular Waterjets (WXJ)
Wärtsilä WXJ modular axial-flow waterjets in sizes 510 to 2350, with up to 3% more thrust, 35% more cavitation margin and 10% lower weight than the earlier LJ mixed-flow design; for fast ferries and naval craft.
Description
Wärtsilä WXJ modular waterjets are single-stage axial-flow waterjets offering a high level of customisation for high-speed vessels. Compared with the predecessor LJ type with mixed-flow pump, the axial pump design delivers up to 3% more thrust, a 25% smaller mounting flange diameter, 10% lower overall weight and a 35% increase in cavitation margin, while keeping small transom interface dimensions.
Range
- Sizes 510 to 2350 (510, 570, 640, 720, 810, 910, 1000, 1100, 1200, 1300, 1400, 1500, 1620, 1720, 1880, 2020, 2180, 2350)
- Steerable (SR) and booster (B) versions
- Mass from 750 kg (510 steerable) to 53,000 kg (2350 steerable)
Key features
- Axial design requires less transom space and allows higher power density on narrower hulls
- Inboard-mounted thrust bearing block
- Optional inboard hydraulics
- Duplex stainless steel high-performance components
- Guaranteed impeller tip clearance due to axial shape
- Customisable and available as fully integrated solutions
Sizing example
A ship with four 1,250 kW engines at 33 knots needs four size 510 waterjets; at 40 knots and 1,250 kW, size 450 can be used.
Applications
Fast ferries, littoral combat ships, fast patrol boats, rescue vessels, fast yachts, fast supply vessels and workboats, and landing craft.
