The OWP-BL300H-D3-3 Electric Coolant Pump is a high-performance fluid handling solution engineered to excel in glycol circulation boosting and diverse industrial cooling applications. Combining advanced 永磁无刷 (permanent magnet brushless) technology with a compact, durable design, this pump delivers reliable operation even in harsh environments, making it a top choice for industries requiring precise fluid circulation and temperature control.

This electric coolant pump stands out with its closed impeller design, which ensures large flow capacity, high pump efficiency, and low noise emission (≤60dB) for quiet operation. The permanent magnet brushless motor not only reduces the pump's overall size and power consumption but also enhances energy efficiency, aligning with modern industrial sustainability goals. Its shaft system features ultra-long-life friction pair materials, paired with a shielded structure, to minimize wear and tear, extending the service life to over 20000 hours. With an IP68 protection rating, the OWP-BL300H-D3-3 is fully protected against dust and continuous submersion, ensuring reliable performance in wet or dirty conditions. Additionally, PWM speed regulation allows for precise flow control, while high/low-level fault feedback signals enable real-time monitoring and quick troubleshooting.

The OWP-BL300H-D3-3 Electric Coolant Pump is specifically optimized for glycol circulation boosting, a critical function in industries such as HVAC, refrigeration, and industrial process cooling. Its rated flow rate of 2880L/H at 17.5M head and maximum flow capacity of 5000L/H make it ideal for boosting glycol-water (50-60% glycol) circulation in large-scale cooling systems, ensuring efficient heat transfer and temperature stabilization. Beyond glycol circulation, this versatile pump is compatible with dielectric oil and electronic fluorinated solutions, expanding its utility to electronic cooling, power generation, and industrial machinery cooling applications. The pump's ability to operate continuously at medium temperatures ranging from -40℃ to 85℃, combined with its 300W rated power and 22M max lift head, makes it suitable for demanding environments where consistent fluid circulation is essential. Whether used in glycol-based cooling loops for data centers, dielectric oil circulation in transformers, or electronic fluorinated solution handling in semiconductor manufacturing, the OWP-BL300H-D3-3 delivers superior performance, durability, and energy efficiency. Its compact design, low noise (≤60dB), and IP68 protection further enhance its suitability for both indoor and outdoor installations, while the long service life of over 20000 hours reduces maintenance costs and downtime for businesses.
