Liquid cooling micropumps in the Japanese market: projected to reach 45.31 million USD by 2026, with a growth rate of 23.2%.
What is a liquid-cooled micro pump? A liquid-cooled micro pump is a small precision pump that circulates coolant within a micro liquid cooling circuit. It sends coolant to components such as cold plates, microchannels, heat exchangers, radiators, and piping, efficiently removing heat from chips, power devices, and battery modules. Compared to conventional pumps, it emphasizes compact design, low noise, low power consumption, stable flow rate, and high reliability. There are various types, including piezoelectric, diaphragm, electromagnetic, small centrifugal, and brushless motor-driven pumps, and it is not a standalone cooling device but a core component of a liquid cooling system that works in conjunction with cooling plates and control electronic components. Global market size of liquid-cooled micro pumps According to the latest research report published by Global Reports titled "Global Market Size, Share, Company Rankings, Sales, and Demand Trend Forecast for Liquid-Cooled Micro Pumps (2026-2032)," the global market is expected to expand from approximately 34.55 million USD in 2025 to about 45.31 million USD in 2026. The compound annual growth rate (CAGR) from 2026 to 2032 is projected to be 23.2%, reaching approximately 158 million USD by 2032.

basic information
AI servers and small electronic devices drive demand The growth of the liquid-cooled micro pump market is supported by the increasing heat density of AI processors and high-performance electronic devices. As air cooling and passive cooling become difficult to manage, pumps that provide sufficient flow rate, head, long continuous operation, and durability are required in AI servers and data centers. On the other hand, in slim smartphones, laptops, and AR/VR devices, piezoelectric micro pumps with thin structures and excellent quietness are a strong option. Furthermore, applications are expanding to communication equipment, high-power lasers, medical devices, and batteries and power electronics in electric vehicles. Production volume, price, and profitability The global production volume in 2025 is estimated to be approximately 874,700 units, with a production capacity of about 1 million units, and the average market price is around $39.5 per unit. The typical gross profit margin is reported to be between 20% and 40%. To achieve both miniaturization and high performance, it is necessary to optimize not only flow rate and pressure but also driving efficiency, component precision, sealing performance, and long-term durability. Particularly in combination with cooling plates that have fine flow paths, it is important to design considering not only the performance of the pump itself but also the overall pressure loss of the circuit and the flow characteristics of the coolant.

Applications/Examples of results
Advancements in Technical Methods and System Integration Products are classified by structure into piezoelectric diaphragm type, small centrifugal type, and small gear type, and by drive method into piezoelectric drive and electromagnetic drive. Additionally, they are categorized into open-type and closed-type liquid-cooled micropumps based on the configuration of the cooling system. In the future, along with miniaturization, increased efficiency, and reduced power consumption, intelligent control of rotation speed, integration of pumps and valves, and integration with cold plates are expected to progress. In automotive applications, resistance to temperature changes and vibrations, compatibility with coolant, and compliance with automotive quality standards are essential.
