HJ Series
The Most successful range of waterjet propulsion in the
world today
TOTAL WATERJET SOLUTIONS With experience spanning over seven decades, HamiltonJet provides a totally integrated waterjet propulsion solution to the marine industry. Proven over many years to perform in all operating conditions, the HamiltonJet HJ waterjet range provides superior thrust, efficiency and cavitation performance over other similar sized waterjet models.
The current HJ Series waterjets include models for power inputs from 260 to 900kW (350hp – 1200hp), with integrated features such as intake and transition duct for easy installation, as well as steering and reverse components.
SPECIFICATIONS
The HamiltonJet Difference
HIGH SPEED PERFORMANCE & EFFICIENCY
Advanced impeller and intake designs provide peak efficiency andperformance over a wide speed range.
LOW SPEED PERFORMANCE
High thrust at low speeds ensures excellent station-keeping, bollardpull, load carrying and manoeuvring.
ACCELERATION
The ability to apply full power at lower speeds ensures fast accelerationfor patrol boats, rescue craft, pilot boats and recreational vessels
STEERING CONTROL
HamiltonJet’s JT steering system out-performs all others, reducing thrust losses when steering to give tighter turns and maintain vessel speed during the turn.
AHEAD / ASTERN CONTROL
HamiltonJet’s split duct reverse deflector provides up to 60% of forwardthrust, resulting in highly responsive control at slow boat speeds whereengine is set to higher than idle RPM and the reverse duct is used toregulate forward and aft thrust.
CONTROLS RESPONSE
HamiltonJet controls respond quickly to skipper input to improvemanoeuvring control and safety. The company develops hydraulic andelectronic control systems to maximise control benefits of its waterjets.
MATERIALS
All HamiltonJet waterjets are manufactured using high quality materialsto ensure the best mix of durability, weight, corrosion resistance andcost.
IMPELLER RATING ACCURACY
Impellers are cast as a single piece to ensure more accurate ratings forall impellers and a better match to peak engine rating.
APPLICATIONS ENGINEERING
HamiltonJet provides the highest level of technical expertise and adviceto builders, designers and end users throughout the entire vesseldesign, build and commissioning phases, and for the operational life ofa vessel.
INTERGRATED ENGINEERING
Each HamiltonJet waterjet is a complete packaged, factory tested,propulsion module, with reverse and steering control systems fullyintegrated with the jet to simplify installation and maintenance.
INTERNATIONAL SUPPORT
HamiltonJet’s service and support network extends around the globe toprovide immediate assistance and spare parts supply.
