HamiltonJet HT series waterjets represent the next evolution in waterjet propulsion technology. Developed from the highly successful HamiltonJet HM waterjet range, HT series waterjets incorporate improved efficiency and cavitation performance to enhance the existing benefits of HamiltonJet's superior propulsion systems. HT series waterjets feature a mixed flow pump with a greater nozzle to inlet ratio than comparible size axial flow waterjets. This provides high efficiency over the entire vessel speed range. A new optimised compact astern deflector retains the performance of HM series type...

HamiltonJet HT Series Features 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 Inboard thrust bearing assembly • 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...

Hydraulic System • Inboard hydraulic sub-assemblies • Independent hydraulic system on each waterjet for redundancy Inboard steering and ahead/astern hydraulics • No hydraulic system plumbing required by the shipyard Adhead/Astern deflector Complete Integrated Design • Each HamiltonJet waterjet is a complete packaged, factory tested, propulsion module • Ahead/Astern & Steering control systems are fully integrated with the jet to simplify installation and maintenance Ahead/Astern Deflector • Split-duct astern deflector provides powerful, high efficiency astern thrust under all conditions of...
