Ship water-jet drive HT810

HT Series – The NEXT EVOLUTION in waterjet propulsion technology The current HamiltonJet waterjet range includes models for power inputs up to 5500kW (7372hp), with integrated features such as intake and transition duct for easy installation, as well as steering and reverse components. Controls • Utilises HamiltonJet’s proven MECS electronic control system • Electronic interface module and wiring loom integrated with the waterjet Thrust Bearing and Water Seal Assembly • Thrust loads from the waterjet impeller are taken by the inboard thrust bearing attached to the intake • Radial loads from the driveline are also taken by this bearing – typically no additional internal support bearings are necessary • Bearing housing is separate from water seal cavity – eliminates water contamination in case of a faulty seal • Thrust bearing oil is circulated through an oil cooler and filter by an integrated circulation pump • Waterseal located at forward end of mainshaft in area of low fluid pressure • Water seal can be replaced from inside the vessel Transition Duct • Factory supplied to suit hull material • Complete Transition Duct may be supplied by HamiltonJet in some cases. In other cases area forward and aft of the Transition Duct to be supplied by the boat builder to details provided by HamiltonJet • Transmits waterjet thrust to hull bottom rather than transom • Designed for optimum performance over a wide speed range • Includes an integrated removable intake protection screen • Waterjet intake flush with hull bottom Low Maintenance • Absence of exposed propulsion gear reduces risk of impact damage
