    Oil-Immersed Submersible Pumps (DQY Series) integrates the advantages of permanent magnet synchronous motors, variable frequency technology, and stainless steel component design. It is widely used in industrial construction, aquaculture, agricultural irrigation, flood control & drought relief, petroleum & chemical industries, and water treatment applications.

    • Garden irrigation
    • Agricultural irrigation
    • aquaculture
    • Flood control and drought relief

    Oil-Immersed Submersible Pumps excel in energy efficiency, reliability, and adaptability by combining high-performance motors with intelligent control systems. They are particularly suitable for applications demanding high energy efficiency and operational stability, making them a superior upgrade over traditional pumps.

    HIGH ENERGY EFFICIENCY

    • Permanent Magnet Synchronous Motor: 10%-20% higher efficiency than traditional induction motors. Maintains high efficiency even under partial load or low-speed operation, minimizing energy waste.

    • Variable Frequency Speed Control: Adjusts motor speed precisely to match actual operational demands. Eliminates the “oversized motor for small load” inefficiency, significantly reducing energy consumption.

    • Energy-Saving Benefits: Substantial long-term electricity cost savings due to optimized performance.

    STABLE OPERATION

    • Soft Start/Soft Stop: Reduces starting current, minimizes grid impact, and extends equipment lifespan.

    • Multi-Protection System: Built-in controller protections: over-voltage, under-voltage, over-current, phase loss, short circuit, water shortage, and over-temperature for enhanced system safety.

    DURABLE & RELIABLE EXTENDED SERVICE LIFE

    • Oil-Immersed Cooling Design: Superior thermal management through oil circulation cooling for both motor and bearings. Prevents performance degradation or damage caused by overheating.

    • Corrosion & Rust Protection: Full stainless steel construction. Suitable for seawater and corrosive environments.

    • Maintenance-Free Permanent Magnet Motor: Significantly reduced failure rate.

    SUPERIOR ADAPTABILITY

    • Wide Operating Range: Variable frequency drive enables precise speed adjustment. Adapts seamlessly to fluctuating flow and pressure requirements.

    • Low-Noise Operation: Frequency conversion minimizes mechanical vibration ideal for noise-sensitive environments.

    EASY INSTALLATION

    • Permanent Magnet Motor – Compact & Lightweight Design: High power density with optimized structure. Space-saving installation due to reduced footprint.

    ECO-FRIENDLY & COST-EFFECTIVE

    • Carbon Emission Reduction: High-efficiency energy-saving performance supports green manufacturing. Complies with global environmental regulations and sustainability standards.

    • Lower Lifetime Costs: Higher initial investment offset by long-term savings. Rapid cost recovery through reduced electricity and maintenance expenses.
