New Hamilton HJ364 Waterjet Released

22nd July 2007

New Hamilton HJ364 Waterjet Released

 
Hamilton Jet continues to set the standard in waterjet design and performance with the release of its latest waterjet model, the HJ364. With a 360mm diameter impeller the HJ364 supersedes the popular HJ362 model, with many additional features and benefits for high speed work and patrol boats, and recreational vessels. 
 
The design of the HJ364 allows a higher engine input power than the HJ362, with a maximum power of 670kW (900hp). A new higher rating impeller option is also available, allowing reduced shaft input speeds and improvements to the already superior cavitation resistance exhibited by Hamilton Jet designs at low speeds and when under loaded conditions. 
 
While the basic specifications of the HJ364 are similar to its predecessor, the new model includes several new design features to improve the installation and operation of the jet. It is available in either zero or five degree shaft angle options to suit different engine alignments and/or trim requirements. A more compact balanced reverse duct is fitted that features the same superior zero-speed and reverse manoeuvring performance. A reverse duct splashguard is fitted and the reverse cylinder is fully inboard. Overall the jet is a more compact, lower profile design. 
 
A key feature of the HJ364 is the new Hamilton Jet “blue ARROW” electronic control system option, in addition to the standard hydraulic control option. This micro-processor driven system integrates the jet steering and reverse controls, engine throttle and gearbox actuation to provide very simple and intuitive vessel control. The HJ364 may also be fitted with Hamilton Jet’s “MECS” electronic control system which provides additional configuration options and interface features.
 
As with all Hamilton waterjets, the HJ364 is compatible with a variety of engine models, either direct driven or via a gearbox, and the flexibility of the jet unit makes it suitable for many different types of vessel in single or multiple installations.
 
The jet features Hamilton’s highly efficient JT steering system, which minimises thrust loss when steering to provide superior manoeuvring control compared to other waterjet steering systems.   The HJ364 features stainless steel stator vane inserts in the tailpipe to improve durability in arduous conditions. Installation of the jet is simplified with the unit able to be fitted from inside or outside the vessel.
 
All hydraulic components are mounted on and fully integrated with the jet, including the oil pump, sensors and valves, the oil cooler, and hydraulic steering and reverse cylinders. This eliminates the need for any additional hydraulic tubing or pumps and simplifies jet installation and maintenance procedures.
 
Finite Element Analysis (FEA) was used extensively to optimise the strength and weight of the various mechanical components of the jet, and the HJ364 waterjet is designed to comply with all the principal classification societies. 
 
This new model can be ordered from any HamiltonJet authorised distributor worldwide. For more information contact Hamilton Jet, PO Box 709, Christchurch, New Zealand. Ph: +64 (3) 962 0530; Fax: +64 (3) 962 0534; Email: marketing@hamjet.co.nz; Website: www.hamiltonjet.co.nz
