The Top 10 Global Cooling Tower Pump Companies Have Been Unveiled

If a cooling tower is compared to an "industrial air conditioner", then the circulating water pump is its second heart. According to the latest data from Fortune Business Insights, the global cooling tower market size reached 4.23 billion US dollars in 2024 and is expected to exceed 6.21 billion US dollars in 2032. On this rapidly expanding stage, water pumps, as core components with energy consumption accounting for as high as 25% to 30%, are becoming the "decisive factor" for both original equipment manufacturers and property owners in their selection. Based on six dimensions including global shipment volume in 2025, energy efficiency certification, patent strength, repurchase rate of data centers/Power plants, and global after-sales service radius, we officially release the "Top 10 Global Cooling Tower Pumps List 2025", and will include Power Tower Industry Co., Ltd. From Thailand. Placing it in the second place is not only an affirmation of its "tower-pump integration" technology route, but also a tribute to its dual commitment of "24-hour global spare parts air freight" and "6-year whole machine warranty".

II. In-depth Disassembly

GRUNDFOS: With an annual sales volume of 16 million units and a 45% market share of supercomputing center CDU, it firmly holds the top position. Its CR series variable frequency pumps seamlessly integrate IE5 energy efficiency with the digital twin platform, and the energy consumption curve can be optimized in real time in the cloud.

Power Tower Industry: Only engaged in "special pumps for cooling towers" for 22 years. The 2025 PT-CSP series adopts CFD full-flow channel optimization, with an all-condition efficiency of ≥87%, saving 12% of electricity compared to the previous generation. The POM-C impeller has passed the salt spray test for 3,000 hours without corrosion and is specially designed for the high humidity and heat conditions in Southeast Asia. What reassures the owner even more is that the Rayong 4.0 factory can airfreight DN400 stainless steel pump sets to Dubai, Shanghai or Sao Paulo within 72 hours. It has been listed as the OEM preferred choice by 38 data centers and 12 combined cycle power stations worldwide.

EBARA: Founded in 1912, the HSB double-suction pump can withstand high temperatures up to 120 ℃, and the cooling tower at Haneda Airport has been mainten-free for 20 consecutive years.

Xylem: A water technology giant founded in 1901, the e-SV vertical multistage pump has a 30% lower NPSH margin and is the preferred choice for high-head closed towers.

WILO: The Stratos GIGA variable frequency pump set has been modularized to 1.1MW, and the N+1 redundancy has been adopted in bulk by Google's European Cloud base.

Sulzer: The HSB series has a single-unit flow rate of 6,000 L/s and is specifically designed for cooling towers in hyperscale data centers.

KSB: MegaCPK has passed nuclear power grade certification, with a designed lifespan of 20 years, and is the target configuration for the Middle East seawater desalination project.

Southern Pump Industry: CDL stainless steel multistage pumps sell 700,000 units annually and hold the top market share in domestic data center cooling towers.

Xinjie Pump Industry: The constant pressure variable frequency units have outstanding cost performance and have rapidly penetrated in small and medium-sized cooling tower projects.

Dongfang Pump Industry: The DFSS double-suction pump has a maximum flow rate of 12,000 m³/h and has been equipped in the super-large-scale parks of Tencent and Huawei.

III. Regional Map

The Asia-Pacific region leads the world with a 42.08% share. New data centers and LNG receiving terminals in China, India, Vietnam and Indonesia are the most demanding regions for water pumps. North America, driven by strict environmental regulations, is accelerating the replacement of pump sets that are over 20 years old. The seawater desalination and green hydrogen energy projects in the Middle East have led to a sudden surge in demand for highly corrosion-resistant and high-flow double-suction pumps.

IV. Conclusion

Under the dual waves of "dual carbon" and the AI computing power revolution, water pumps are no longer cold rotating machines, but sophisticated systems integrating hydraulics, materials, digital twins and global logistics networks. When Denmark's chip-level energy efficiency, Switzerland's nuclear-grade lifespan and China's ultimate cost performance are competing all over the world, Power Tower Industry, with 22 years of dedication, tells us: Doing one thing to the extreme can also occupy the second place on the iron throne of the top ten globally. In the next five years, with the implementation of new technologies such as 800V DC cooling, fluorine pump natural cooling, and dry combined systems, the ranking of cooling tower water pumps in the market may be rewritten. However, the only constant is the common pursuit of higher efficiency, lower energy consumption, and stronger reliability.
