Doen
| Waterjets & Controls DOEN Pacific Pty. Ltd., has been designing and manufacturing Doen Waterjet Propulsion Systems in Melbourne, Australia since 1970. Over 45 years of commercial operational, design, and manufacturing experience, in conjunction with our ongoing Research and Development Programs, ensures that our current range of waterjet models offer outstanding performance and reliability. All models are built to meet the exacting standards of the marine classification societies. Doen Pacific’s expertise in waterjet propulsion application and installation, ensures correct selection and matching of the Doen waterjets to marine engine combinations from 100 kW to over 3000 kW (120hp to over 4000hp). Doen waterjets are currently in operation in many countries throughout the world having gained a worldwide reputation for reliability, simplicity, performance, service and support.
100 Series The DOEN 100 Series range of models can be matched to engines from 100kW to 900kW. These commercially rated units employ the latest in Waterjet Propulsion technology developed over 40years of in field experience, together with our ongoing Research and Development programs.
The 100 Series waterjets are constructed from strong, corrosion resistant and corrosion compatible materials. The stainless steel impeller is a one-piece casting, housed in a stainless steel liner. The intake ducting, impeller casing, and discharge nozzle complete the pump housing and are all manufactured from cast aluminum. The steering and reverse ducting is also manufactured from cast aluminum. A modular construction is used for simplicity of assembly and ongoing maintenance. This minimizes the need for special tools to remove these components.
The 100 Series pump features a single stage axial flow impeller design, optimised to deliver high volume thrust. This provides superior cavitation resistance and enhanced load-carrying ability together with excellent top speed performance. Each model has a comprehensive range of efficient high thrust impellers which when coupled with DOEN’s engineering expertise in waterjet propulsion application and installation, ensures correct selection and matching of waterjet, engine and gearbox combinations.
The DOEN 100 Series of waterjets can be installed as single, twin or triple jets in fibreglass, aluminium and steel hulls. They can also be supplied as booster jets.
200 & 300 Series The DOEN 200 Series range of models can be matched to engines from 400kW to 2500kW. The DOEN 300 Series range of models can be matched to engines from 1300kW to 4000kW. These high performance units are specially designed and built for continuous commercial use and to meet the exacting standards of marine classification societies. They can be installed as single or as multiple jets in fiberglass, aluminum or steel hulls. They can also be supplied as booster jets.
The prefabricated duct is manufactured from Aluminum or Steel plate material resulting in an extremely strong and lightweight structure. The duct is supplied ready to weld or bolt in (Fiberglass vessels). Custom designs are possible to optimise vessel performance and to improve installation and machinery interfacing.
The 200 Series waterjet is manufactured using only corrosion resistant materials. The impeller, impeller casing and discharge nozzle are manufactured from stainless steel to provide maximum service life in the most arduous operating environment with extreme resistance to erosion, corrosion and cavitation. The balance of the waterjet is manufactured from marine grade aluminum. This combination of materials provides a new and unique alternative to operators at a very competitive price.
A CAN BUS based electronic control system provides a fully integrated multi-station waterjet, engine and marine gear control. The system also provides alarm, monitoring, back up and emergency control function.
eDOCKmulti function electronic joystick for single lever vector control and close quarter docking is available. |
