# Stainless Steel Brushless Electric Water Pump OWP-BL400H-D2-21: Perfect for EV Charging & Swapping Station Liquid Cooling

The OWP-BL400H-D2-21 stainless steel brushless electric water pump is a high-performance solution tailored for critical liquid cooling needs, with a key focus on **EV charging and swapping station liquid cooling systems**. It also excels in other high-demand applications such as data center server liquid cooling, AI computing center liquid cooling equipment, small marine engine/battery cooling, copper-containing component liquid cooling, energy storage cabinet/lithium battery energy storage liquid cooling, and off-grid area power generation energy storage thermal management.

### Core Advantages

- **Exceptional Durability**: The water-contacting parts are made of stainless steel, ensuring resistance to corrosion and wear, while the working life exceeds 20,000 hours for long-term reliability.

- **Comprehensive Protection**: Equipped with reverse connection protection, no-load protection, locked-rotor protection, and over-voltage/under-voltage protection, safeguarding the pump and connected systems from damage.

- **Superior Environmental Adaptability**: With an IP68 protection rating, it operates flawlessly in harsh environments with temperatures ranging from -40℃ to 85℃ and relative humidity up to 90%.

- **Efficient Performance**: Features PWM speed regulation for precise flow control, and delivers a minimum head of 20m at a flow rate of 3000L/h, meeting the high cooling demands of EV charging and swapping stations.

- **User-Friendly Design**: Flange quick-connect inlet and outlet simplify installation and maintenance, while high/low level signal error feedback enables real-time monitoring and troubleshooting.

- **Low Noise Operation**: Produces a noise level of ≤60dB(A) at 1m under load, ensuring a quiet working environment.
