This industrial-grade DC liquid cooling pump is engineered to deliver efficient, consistent heat dissipation for demanding applications. Operating on the principle of electromagnetic drive, the pump converts electrical energy into mechanical power to circulate cooling fluid, with PWM (Pulse-Width Modulation) speed control enabling precise flow regulation based on real-time thermal demands. Its robust design ensures stable performance across extreme temperature ranges, making it ideal for scenarios where thermal stability directly impacts system reliability.

#### Key Applications

The pump excels in diverse liquid cooling scenarios, including **data center server liquid cooling**, **small marine engine/battery cooling**, **copper-component liquid cooling systems**, **energy storage cabinet/lithium-ion energy storage cooling**, and **electric vehicle (EV) charging/swapping station liquid cooling**. It is specifically tailored for systems requiring efficient heat transfer in compact or harsh environments.

#### Core Advantages

- **Precision PWM Speed Control**: Offers ±2% duty cycle accuracy, with adjustable speeds (stop, min, linear control, max) across 50-1000Hz (recommended 500Hz) for optimized energy efficiency.

- **Exceptional Durability**: Boasts a working life exceeding 20,000 hours, IP68 protection (dust/waterproof), and resistance to -40℃ to 85℃ operating temperatures (media and environment).

- **Comprehensive Protection**: Features reverse polarity, no-load, locked-rotor, over-voltage, and under-voltage protection to prevent damage and ensure operational safety.

- **High Performance**: Delivers 400W (±5%) rated power, 3000L/h flow rate with ≥20m head, and low noise (≤60dB(A) at 1m under load) for quiet, efficient operation.

- **Superior Sealing**: Maintains airtightness with ≤0.8mL/min leakage at 0.35Mpa, preventing fluid loss and system contamination.
