Canned Pump- DC48V 2.5KW 275L_min 30m Head for Energy Storage Thermal Management

The OWP-BL2000H-D3-1 is a horizontal single-stage centrifugal canned electronic pump designed specifically for thermal management in energy storage projects. It integrates advanced canned motor technology and permanent magnet synchronous brushless motor design to realize efficient, leak-free circulation of heat transfer media.

With a rated voltage of DC48V and a rated power of 2500W, the pump delivers a flow rate of 275 liters per minute at a head of 30 meters, ensuring sufficient heat transfer capacity for high-power energy storage systems. Its robust structural design and IP67 protection level enable reliable operation in complex environmental conditions, while multiple built-in protection functions guarantee long-term operational stability.

Energy storage systems, especially large-scale energy storage projects, generate substantial heat during charging and discharging cycles, requiring thermal management solutions with high flow rates, stable head output, and consistent heat dissipation performance. The harsh operating environments of these projects—including wide temperature fluctuations, high humidity, and potential exposure to dust or water—demand equipment with strong environmental adaptability and sealing reliability.

Additionally, energy storage systems operate continuously for long periods, necessitating components with extended service life to minimize maintenance downtime and costs. Electrical safety and system compatibility are also critical, as thermal management equipment must integrate seamlessly with existing control systems and withstand voltage fluctuations or abnormal operating conditions without failure.

The OWP-BL2000H-D3-1 is tailored for thermal management systems in energy storage projects, where it circulates deionized water or antifreeze to transfer heat generated by battery packs during operation. Its 275L/min flow rate and 30m head ensure efficient heat dissipation, even for high-power energy storage modules, while the -40℃~60℃ ambient temperature range and -30℃~60℃ medium temperature range enable reliable operation in both cold and hot climates.

The pump operates based on the centrifugal force principle: the brushless permanent magnet synchronous motor drives the impeller to rotate at high speed, creating negative pressure at the inlet to draw in the heat transfer medium (deionized water or antifreeze). The rotating impeller imparts kinetic energy to the medium, which is then converted into pressure energy to push the medium through the outlet into the thermal management loop.

The canned motor design isolates the motor rotor from the medium, eliminating mechanical seals and achieving leak-free operation. The built-in control module regulates motor speed to maintain constant flow output, while real-time monitoring of electrical parameters (voltage, current) and operating conditions (temperature, media presence) triggers protective actions (e.g., shutdown, speed adjustment) when abnormalities are detected, ensuring safe and stable operation.

Based on the industry convention that 1.5L/min of flow rate corresponds to 1KW of heat dissipation capacity, the OWP-BL2000H-D3-1’s maximum flow rate of 275L/min (at 30m head) can theoretically support a heat dissipation range of approximately 180KW to 190KW for host equipment in energy storage systems.

This range is for reference only, as actual matching depends on factors such as system pipeline resistance, medium thermal conductivity, and operating temperature. For systems with longer pipelines or higher resistance, the effective flow rate may decrease slightly, and selection should account for a 10-15% margin to ensure sufficient heat dissipation capacity.
