Engineered to meet the rigorous cooling demands of 5G infrastructure, the OWP-BL43-440C Electric Coolant Pump delivers reliable, high-performance thermal management for high-power AAUs (Radio Frequency Units) in 5G base stations. With advanced BLDC motor technology, multi-layer protection mechanisms, and extreme environmental adaptability, this pump ensures uninterrupted operation of critical 5G equipment—even in harsh outdoor conditions.

• Precision Flow Control & Efficiency: Equipped with constant flow regulation and PWM speed adjustment, the pump adapts dynamically to cooling demands while maintaining optimal performance. Its BLDC motor, validated through professional electromagnetic theory design, achieves 3-5% higher efficiency than industry counterparts.
• Superior Hydraulic Performance: Advanced hydraulic simulation software optimizes the impeller and volute design, ensuring perfect matching for enhanced hydraulic efficiency—delivering a maximum flow of 4600L/H and lift head of 23M to tackle high-heat loads in 5G AAUs.
• Comprehensive Protection Mechanisms: Integrated reverse polarity, dry running, over-voltage, over-current, overload, and over-temperature protection safeguards both the pump and 5G equipment, minimizing downtime.
• Extreme Environmental Adaptability: With an IP68 rating, operating temperature range of -40℃ to +85℃ (medium), and ambient temperature resistance up to +120℃, the pump performs reliably in harsh outdoor conditions—from freezing winters to scorching summers.
• Long-Lasting & Quiet Operation: A service life exceeding 20,000 hours ensures long-term reliability, while noise control ≤60dB maintains a quiet working environment.

5G base stations rely on high-power AAUs to deliver fast, reliable connectivity—but these units generate significant heat that can degrade performance or cause failures if not properly managed. The OWP-BL43-440C Electric Coolant Pump is specifically engineered to address this challenge, providing efficient, consistent cooling for 5G AAUs.

Its high flow rate (up to 4600L/H) and lift head (23M) ensure effective heat dissipation, even for high-power AAUs operating at maximum capacity. The clamp quick-connect fitting enables easy installation and maintenance, while the magnetic force transmission (shield pump structure) prevents leaks—critical for protecting sensitive electronic components.

With resistance to extreme temperatures, humidity, and dust (IP68 rating), the pump thrives in outdoor 5G base station environments, ensuring uninterrupted operation 24/7. Whether deployed in urban areas, remote regions, or coastal locations, the OWP-BL43-440C delivers the reliability and performance 5G networks demand.

Invest in the OWP-BL43-440C Electric Coolant Pump for robust, efficient cooling that keeps your 5G base station high-power AAUs running at peak performance.
