2.5KW Electronic Coolant Circulation Pump- DC48V Input for Energy Storage Thermal Management

The OWP-BL2000H-D3-1 is a horizontal single-stage centrifugal canned electronic pump designed specifically for thermal management systems in energy storage projects. As a core component of heat dissipation infrastructure, this pump is engineered to deliver reliable fluid transfer performance with deionized water or antifreeze as the working medium. Its integration of a brushless permanent magnet synchronous motor and canned centrifugal structure ensures high efficiency, long service life, and leak-free operation—key requirements for maintaining stable thermal conditions in energy storage applications. With a rated voltage of DC48V, maximum flow rate of 275 L/min at 30m head, and IP67 protection rating, the pump is optimized to adapt to harsh operating environments while meeting the strict thermal management demands of energy storage systems.

Energy storage thermal management faces unique technical challenges that directly impact system safety and operational efficiency. First, leakage risks in fluid circulation systems can lead to short circuits or equipment damage, posing severe safety hazards in high-voltage energy storage environments. Second, energy storage systems operate under fluctuating voltage conditions, requiring pumps to maintain stable performance across a wide input voltage range without efficiency loss. Third, extreme environmental conditions—including temperatures ranging from -40℃ to 60℃ and high humidity (5~95%)—demand robust protection and material durability to ensure continuous operation. Fourth, thermal management systems require precise flow control to match varying heat loads, as inconsistent flow can result in overheating or inefficient energy consumption. Fifth, long-term reliability is critical, as unplanned downtime for pump maintenance can disrupt energy storage operations and incur significant costs. Additionally, noise pollution in industrial settings necessitates low-noise operation to comply with workplace standards. Finally, compatibility with standard communication protocols (e.g., RS485) is essential for seamless integration into centralized monitoring systems, enabling real-time performance tracking.

To address the aforementioned industry main requirements, the OWP-BL2000H-D3-1 integrates technical features that directly translate to practical solutions:

1. Leak-free Operation: The centrifugal canned pump design eliminates dynamic seals, completely eliminating leakage risks—a critical solution for high-voltage energy storage environments where fluid leakage could cause catastrophic failures.
2. High Efficiency & Long Lifespan: Equipped with a brushless permanent magnet synchronous motor, the pump achieves high energy conversion efficiency while extending the service life to ≥40,000 hours. This directly addresses the demand for long-term reliability, reducing maintenance frequency and operational downtime.
3. Stable Voltage Adaptability: With a working voltage range of DC42~58V, the pump maintains consistent performance under fluctuating power supply conditions, ensuring uninterrupted thermal management even when the energy storage system’s output voltage varies.
4. Precise Constant Flow Control: The built-in constant flow control function ensures stable fluid delivery regardless of pressure changes, matching the dynamic heat load requirements of energy storage systems and preventing overheating or inefficient cooling.
5. Comprehensive Protection Mechanisms: The pump incorporates reverse connection protection, dry running protection, overvoltage/overcurrent protection, and overload/overtemperature protection. These features safeguard the pump and the entire thermal management system from damage caused by abnormal operating conditions, enhancing overall system safety.
6. Harsh Environment Adaptability: With an an IP67 protection rating, the pump is dustproof and waterproof, capable of operating in humidity levels of 5~95% and ambient temperatures from -40℃ to 60℃. The cast aluminum wetted parts ensure corrosion resistance against deionized water and antifreeze, meeting the material durability requirements of extreme industrial environments.
7. Low Noise Operation: Operating at ≤70dB (measured 1 meter from the pump), the pump complies with industrial noise standards, addressing the demand for low-noise equipment in workplace settings.
8. Seamless System Integration: The RS485 communication interface enables real-time data transmission to centralized monitoring systems, supporting remote performance tracking and facilitating integration into the overall energy storage control architecture.

The OWP-BL2000H-D3-1 is exclusively designed for thermal management in energy storage projects. Its high flow rate (275 L/min at 30m head) and rated power of 2500W enable efficient heat transfer, making it suitable for large-scale energy storage systems where rapid heat dissipation is critical. The pump’s compatibility with deionized water and antifreeze aligns with the fluid requirements of energy storage thermal management systems, while its wide operating temperature range (-40℃ ~ 60℃) ensures performance stability in both indoor and outdoor energy storage installations. Additionally, the IP67 protection rating and corrosion-resistant cast aluminum components make it adaptable to the harsh operating conditions commonly encountered in energy storage facilities, ensuring reliable long-term operation.

The OWP-BL2000H-D3-1 operates based on the principle of centrifugal force generated by a rotating impeller. The brushless permanent magnet synchronous motor drives the impeller to rotate at high speed, creating negative pressure at the inlet that draws the working medium (deionized water or antifreeze) into the pump cavity. The rotating impeller imparts kinetic energy to the fluid, which is then converted into pressure energy as the fluid flows through the volute, generating the required head to circulate the medium through the energy storage thermal management system. The canned structure isolates the motor from the fluid, eliminating dynamic seals and preventing leakage. The built-in constant flow control system adjusts the motor speed in real time based on pressure changes, ensuring a stable flow rate regardless of system resistance. Comprehensive protection mechanisms monitor operating parameters (e.g., voltage, current, temperature, and fluid presence) and trigger protective actions (e.g., shutdown, speed adjustment) when abnormalities are detected, safeguarding the pump and the thermal management system. The RS485 communication interface transmits operational data (e.g., flow rate, temperature, status) to the central control system, enabling real-time monitoring and remote management.

In thermal management systems, the industry generally follows the calibration method of "1.5L/min flow rate corresponding to 1KW heat dissipation capacity" to match pumps with heat load requirements. Based on this industry practice, the OWP-BL2000H-D3-1’s maximum flow rate of 275 L/min at 30m head can be used to estimate its matched range for heat dissipation systems. Calculating based on the industry’s common calibration, the pump’s flow capacity corresponds to a heat dissipation range of approximately 183KW (275 L/min ÷ 1.5L/min per KW). This indicates that the pump is suitable for CDU (Cooling Distribution Unit) and other heat dissipation systems supporting energy storage hosts with heat loads within this approximate range. When selecting, it is also necessary to consider the actual system pressure (compatible with -0.9Bar ~ 10Bar), medium type (deionized water or antifreeze), and environmental conditions (temperature, humidity, altitude) to ensure alignment with the pump’s specifications. Additionally, the pump’s rated power of 2500W should be compatible with the power supply capacity of the energy storage system to avoid operational issues caused by power mismatches.
