Features
Optimized Blade Design
The high-angle, multi-blade design effectively reduces vibration and cavitation, ensuring smooth operation and protecting onboard equipment.
Strong Torque at Low Speeds
Provides strong torque at low speeds, crucial for the slow, stable movement required when hauling in nets.
Fuel Efficiency
Optimized blade geometry reduces engine load, helping to lower fuel consumption during long-haul fishing operations.
Customizable Specifications
Diameter, pitch, number of blades, blade skew, and hub design can be customized to suit vessel size, engine power, and fishing conditions.
FAQ
Q: Why is low-speed performance important?
A: Purse seiners need to move slowly and steadily while deploying nets or hauling catches. The propeller provides smooth, controllable thrust at low RPMs.
Q: What materials are used for these propellers?
A: Common materials include bronze, nickel-aluminum bronze, or stainless steel, which resist corrosion, wear, and seawater erosion.
Q: How many blades are typical for a purse seiner propeller?
A: Most designs use 4–5 blades. More blades reduce vibration and improve thrust stability at low speeds.
Q: Can these propellers be customized?
A: Yes. Buyers can customize diameter, pitch, blade number, blade skew, hub design, and material to match vessel size, engine power, and fishing conditions.
Q: How does blade design affect performance?
A: Blade shape, skew, and pitch influence thrust, torque, cavitation resistance, and vibration. Proper design ensures smooth operation and protects onboard equipment.
