Entering a New Growth Market: Liquid Data Center Cooling
As artificial intelligence (AI), cloud computing, and high-performance computing continue to accelerate, data centers are under increasing pressure to manage rising heat loads while maintaining maximum uptime, efficiency, and scalability.
To meet these requirements, many operators are transitioning from traditional air cooling to advanced liquid cooling technologies. As a result, pumps have become a critical component of modern cooling infrastructures, ensuring reliable coolant circulation, precise temperature control, and continuous 24/7 operation.
This development opens a significant growth opportunity for CIRCOR Pumps and Allweiler.

Why This Market Matters
- Liquid cooling is rapidly becoming a strategic technology for next-generation data centers supporting AI and high-performance computing applications.
For OEMs, cooling system manufacturers, system integrators, EPCs, and end users, the challenge is no longer simply removing heat. The focus has shifted toward maximizing system availability, reducing energy consumption, and enabling future computing expansion.
For Allweiler, this trend is particularly relevant because cooling requirements are evolving. While earlier liquid cooling systems often relied on smaller commodity pumps, today's Cooling Distribution Units (CDUs) increasingly require higher flow rates and more demanding operating conditions. As a result, pump requirements are moving into the performance range of industrial pump solutions. This shift creates new opportunities for Allweiler to apply its proven expertise in industrial fluid handling to a rapidly growing market segment.

Understanding Customer Challenges
When engaging with customers, focus first on understanding their cooling architecture, operational requirements, and future growth plans.Typical challenges include:
- Achieving reliable 24/7 system operation Minimizing downtime and operational risk
- Ensuring compatibility with various cooling fluids
- Preventing leaks and maintaining system safety
- Improving energy efficiency and reducing operating costs
- Integrating pumps into Cooling Distribution Units (CDUs)
- Designing scalable systems for future AI and HPC demands
These challenges create opportunities to demonstrate how proven industrial pump technology can contribute to overall cooling system performance and reliability.
The As our understanding of this market continues to evolve, we are increasingly focusing on Cooling Distribution Unit (CDU) manufacturers, where pump selection plays a critical role in overall system performance. For many CDU applications, requirements follow a similar pattern. The primary variables are flow rate, pressure requirements, and the choice between a mechanically sealed solution or a magnetic drive design.
- To address these needs, Allweiler is currently focusing on two proven pump platforms:
- NB Series
Mechanically sealed centrifugal pumps designed for demanding industrial cooling applications.

Beyond pump selection itself, customer discussions increasingly focus on system integration topics, including:
- Integration of pumps into CDU designs
- Control and monitoring concepts
- Interface and communication requirements
- Reliability and maintenance considerations
- Opportunities to simplify overall system design
These discussions provide an excellent starting point for identifying how Allweiler can support customers not only with pump technology, but also with application expertise and system integration know-how.
We encourage all channel partners to actively monitor developments in the data center market within their regions. In particular, keep an eye out for:
- CDU manufacturers
- Companies developing liquid cooling systems
- Planned or expanding data center projects
- Engineering companies involved in cooling infrastructure
- Allweiler is ready to support these opportunities.
