Perfect interaction between gear and propeller results in perfect performance. Our gears are characterized by high efficiency degrees and great longevity. Development based on difficult givens in conditions of use.
In adequacy to your ship, our tailored shaft lines meet your visions and needs. One of many great features is the low maintenance effort our shaft lines require.
For ships with high transmission performances, it is recommended to install a propeller nozzle that helps to provide the necessary thrust. This results in an increase of the effective transmission of the engine performance despite a constant diameter. Therefore, propeller nozzles are recommended for ships that are to carry great weights in shallow waters. Each propeller nozzle is manufactured individually to accommodate any given operating conditions.
Not only do we offer classic nozzles such as the 19A or 37 types but also wing nozzles for fast ships and Optima nozzles for best thrusts possible in case of extreme strains. All nozzles are available either stationary or rotatable. In addition, we also offer special devices for the application to rudder propellers. Promarin focuses on innovative designs which correspond the constant changes in technical and economic requirements.
Operating conditions, ship design, noise emission requirements, speed and thrust conditions define each individually manufactured propeller. Our propellers are made of premium, well-proven materials such as propeller bronze or stainless steel. High degrees of efficiency, low noise emission and unconditional reliability distinguish our products.
State-of-the-art techniques combined with decades of experience enable us to build propellers of the highest efficiency.
The number of blades will be determined by our expertise and precise calculations in accordance with the actualities. An ideal ascending slope as well as vibrational behavior and noise patterns define our design.
We combine efficiency and maneuverability in innovative rudder designs. We find solutions that match your requirements, whether it’s a profile rudder, a flanking rudder or a flap rudder. Our innovative technologies create state-of-the-art rudder that can conquer the most difficult challenges.
