Product Overview
The Diesel Engine Long-Arm Paddlewheel Aerator (16 Impellers, 16HP) is specially designed for large-scale shrimp and fish farming ponds, particularly in areas where stable electricity is unavailable. Powered by a robust 16HP diesel engine and equipped with a long-arm paddlewheel system, it provides strong water circulation and high oxygen transfer capacity over a wide pond surface.
This aerator is the ideal solution for high-density aquaculture farms that demand reliable, high-horsepower aeration to maintain dissolved oxygen, improve water quality, and support healthy shrimp growth.
Key Characteristics
- High Efficiency Gear Transmission
- Arcuate bevel gears replace traditional worm gears, improving efficiency and saving over 20% energy compared with conventional models.
- Durable Gear Material
- Bevel gear made of chromium-manganese-titanium alloy with surface carbonitriding treatment, ensuring long service life and high rigidity.
- Reliable Mechanical Seal
- Mechanical seal design extends service life 2–3 times longer than traditional oil seals, reducing maintenance needs.
- Motor Protection System
- Built-in protector prevents accidental motor burn-out, enhancing operational safety and reliability.
- Premium Materials
- HDPE floats: corrosion-resistant and UV-protected
- Nylon impellers: strong and wear-resistant
- 304 stainless steel solid shaft: durable and anti-corrosion
- Sturdy frame: long-lasting and stable in harsh environments
Advantages
- Wide-area Oxygenation: With 16 impellers on a long-arm design, the aerator creates strong water currents and turbulence, ensuring dissolved oxygen is distributed evenly across large ponds.
- Diesel-driven Independence: Perfect for remote aquaculture regions lacking stable electricity, the diesel engine ensures powerful and continuous aeration.
- High Horsepower for Intensive Farming: 16HP engine delivers the torque and performance needed for large-scale shrimp ponds with high stocking density.
- Energy-efficient Operation: Advanced gear design reduces power loss, offering better performance and lower fuel consumption compared with traditional models.
- Durability & Low Maintenance: High-quality materials and mechanical seals extend lifespan and minimize downtime.
Application
✅ Shrimp ponds with large surface area
✅ Aquaculture sites in power-deficient or off-grid regions
✅ High-density fish and shrimp farming requiring continuous, high-capacity aeration
