| Introduce the basic functions of the product |
Core basic functions It adopts the principle of axial flow propulsion to realize the underwater medium transportation of large flow rate and low head, and is suitable for fluids without large particulate impurities such as clean water and light sewage. Specialized functions Agricultural irrigation: Long-distance water conveyance and pumping for large areas of farmland, orchards, and tea gardens. Flood control and drainage: Rapid drainage of urban flooding, factory waterlogging, and low-lying areas. Water circulation systems: Circulating water supply for rivers, landscape lakes, and power plant cooling systems. Engineering drainage: Daily drainage and emergency water conveyance for water conservancy projects and industrial and mining enterprises. |
| Usage Environment |
1. Media environment: Clean water, lightly polluted water, rainwater, etc.; free from large particulate impurities (particle size < 5mm), strong corrosiveness, and fibrous entanglement. 2. Diving depth: The standard maximum diving depth is 5m, while the customized version can reach 10m; the minimum submersion depth must cover the water inlet bell mouth. 3. Temperature environment: Medium temperature: 0℃~40℃; ambient temperature: -20℃~50℃. 4. Installation environment: Underwater vertical installation; suitable for ponds, rivers, reservoirs, wells, water storage tanks, sump pits and other scenarios; no pump room required. 5. Operating environment: It can operate continuously or intermittently; it is suitable for water conveyance conditions with large flow and low head; the explosion-proof type can be used in outdoor environments with flammable and explosive gases. 6. Electrical environment: It is compatible with three-phase 380V power supply; with an IP68 protection rating, it can operate underwater for extended periods. |
| Product Advantages |
1. Direct submersible connection, easy installation. 2. High flow rate, low head, high efficiency. 3. No pump room required, saving space. 4. High protection level, durable underwater. 5. Stable operation, extremely low noise. 6. Energy saving and low maintenance costs. 7. Wide compatibility, strong compatibility with various operating conditions. 8. Complete range of models, customization supported. |
