The OWP-BL43-426C pump plays a critical role in the liquid cooling systems of 5G base station AAUs (Radio Frequency Units)—a core application where its performance directly impacts network stability and energy efficiency. 5G AAUs operate at significantly higher power densities than 4G counterparts, generating intense heat during signal transmission and data processing. Excess heat can degrade AAU performance, shorten component lifespans, or even cause unexpected downtime, which is detrimental to 5G’s low-latency and high-reliability requirements.
This pump addresses these challenges by delivering consistent, high-efficiency cooling. Its rated flow rate of 2400L/H (up to 5000L/H max) ensures a steady supply of cooling media (such as 50-60% glycol-water mixtures) to absorb heat from AAU components. With a maximum lift head of 20M, it can circulate media effectively even in larger cooling loops, while PWM speed regulation allows real-time adjustment based on the AAU’s heat load—reducing energy waste when cooling demands are low. The IP68 rating also makes it suitable for outdoor 5G base station environments, where it may be exposed to dust, rain, or temperature fluctuations (-40℃ to +85℃), ensuring year-round reliability. By maintaining optimal operating temperatures for AAUs, the pump helps 5G networks deliver consistent performance and lower overall energy consumption.
