Municipal Water Supply and Drainage

Perfect for deep wells in water treatment plants, sewage discharge, and urban flood control, the pump’s customizable long shaft ensures precise adaptation to different water depths. The external motor allows for easy outdoor maintenance, and its IP55-rated protection resists dust, rain, and snow, ensuring continuous and safe operation for urban water supply and drainage systems.

Mining Dewatering

In medium and large-scale mines, the pump handles deep well drainage and tailings pond dewatering with water levels from 5–50 meters. The sand-proof bottom design prevents abrasive particles from entering the pump, while durable materials ensure stable operation with slightly sedimented water, helping maintain safe and efficient mine operations.

Water Conservancy Projects

Ideal for large reservoir water transfer, river ecological replenishment, and water hub conveyance, the pump accommodates varying water depths with a wide flow range of 800–25,000 m³/h, matching diverse project scales. Its stable transmission system ensures long-term, uninterrupted water transfer for critical water conservancy applications.

Power Plant Cooling Water

For power station circulation, the Durable Deep well vertical axial flow pump can extract water from the bottom of cooling pools, providing high-efficiency flow to meet large cooling demands. The variable frequency control allows the pump to adjust flexibly to the plant’s operational water requirements, ensuring consistent performance and energy efficiency.How to use this product correctly?

Ensuring proper operation and regular maintenance is essential for the long-term stable performance of the Deep Well Vertical Axial Flow Pump. Designed with an external motor, long-shaft transmission, and deep water adaptability, following these key guidelines will help maximize pump reliability and fully leverage its deep-water performance.

Installation Tips

Long-Shaft Alignment: Make sure the pump is vertically installed and the pump shaft aligns precisely with the motor shaft to avoid eccentric vibration that can damage components. The base must be firmly fixed and leveled, and for deep-water installations, intermediate supports should be added to enhance shaft stability.

Motor Placement & Protection: Install the external motor away from standing water. For outdoor use, a protective rain and dust cover ensures the IP55 rating is effective. Proper cable routing is essential to avoid dragging, crushing, or damage, and all connections must be properly sealed.

Pump & Sand Protection Check: Ensure the bottom sand-proof device is installed correctly, manually rotate the shaft to confirm smooth movement without obstruction, then proceed with test operation.

Operation and Maintenance

Real-Time Monitoring: Continuously check motor current, voltage, shaft temperature, and pump vibration. If abnormal current, unusual noise, rapid temperature rise, or increased vibration occurs, stop the pump immediately and inspect. Avoid dry running, and do not pump media exceeding 1.5% sand content or 60°C water temperature.

Routine Maintenance: Every 3–6 months, check motor insulation, bearing lubrication, and seal integrity. Replenish or replace lubricant as needed. Clean the sand-proof device and pump cavity to remove sediment, inspect the long shaft for wear, and straighten or replace it if necessary.

Long-Term Storage: Before prolonged shutdown, drain the pump cavity and apply anti-corrosion treatment to the shaft, impeller, and other components. Before restarting, perform a full equipment check to ensure safe operation.

By following these installation, operation, and maintenance guidelines, the Deep Well Vertical Axial Flow Pump delivers safe, efficient, and reliable performance for deep-water municipal, mining, water conservancy, and power projects.
