Panasonic Develops a Cooling Water Circulation Pump for Data Centers — Promoting the Strategic Enhancement of the Pump Business

Last Updated on: 13th June 2025, 01:08 am

Osaka, Japan — Panasonic Corporation today announced that its Living Appliances and Solutions Company (Panasonic) has marked the 70th anniversary of its pump business. The company’s pump business, which began with home pumps (well pumps) that supply water to homes, has consistently contributed to the realization of comfortable and affluent lifestyles through built-in pumps for water heaters, heating appliances, and bathroom equipment. This time, Panasonic will enter the cooling pump market for data centers, aiming to expand its business areas and contribute to customers.

In recent years, with the evolution of AI technology, the number of data centers has been increasing globally. In generative AI data centers, the heat generated per CPU or GPU chip is rapidly increasing due to advanced computational processes. Previously, air cooling using air conditioners and fans was the mainstream method. However, growing demand for more effective and efficient cooling has brought increased attention to liquid cooling, which has high cooling efficiency.

Panasonic has developed a next-generation cooling water circulation pump specifically for data center cooling, integrating its proprietary technology and system design capabilities refined over 70 years of its pump business. This product is designed for integration into CDUs (Coolant Distribution Units), the core components of cooling systems, and offers high efficiency, a compact form, and long service life. It meets the cooling needs of next-generation infrastructure by simultaneously reducing environmental impact and ensuring stable operation.

Starting with its entry into the data center market, Panasonic will contribute to cooling solutions for infrastructure-related heat countermeasures to expand its pump business, aiming for cumulative shipments of 100 million units by 2035. The company will continue to contribute to safe and comfortable lifestyles and industrial development through reliable technology, while earnestly responding to environmental changes and customer feedback.

New product features

1. High performance

By fully utilizing advanced simulation technologies, such as magnetic field analysis, fluid dynamics analysis, and flow analysis, Panasonic has achieved a 75% improvement in pump performance (from 40 to 70 L/min) while maintaining the same size as conventional pumps. This product contributes to improved energy efficiency across entire data center systems and simplifies cooling system design.

2. Compactness

A compact housing has been achieved by leveraging the company’s design expertise, honed through the development of built-in pumps for equipment. This feature enabled the circulation pump to be housed within CDUs that have limited space. The compact housing offers layout flexibility, significantly increasing the design freedom of CDUs.

3. Long life

The adoption of submersible sliding bearings and optimized structural design ensures long-term stable operation and reduces maintenance workload. This feature supports high reliability and cost optimization in data center operations.

Panasonic pump business — 70 years of progress

Panasonic’s pump business began with the launch of home pumps (well pumps) in 1955.

In 1980, the company began developing and selling built-in AC pumps for water heaters, contributing to enhanced product value (reheating function) provided by them. Since then, the company has been developing products that simultaneously deliver energy efficiency and environmental friendliness, including built-in DC pumps for equipment. In 2025, the pump business has marked its 70th anniversary, with cumulative shipments exceeding 53 million units.

The range of appliances incorporating these pumps extends beyond the company’s own products. Manufacturers in Japan and abroad have also adopted Panasonic pumps in their combustion-type water heaters and heating appliances as well as air-to-water heat pumps. Additionally, the new pump has been adopted in cooling equipment for data centers in the current fiscal year. Panasonic pumps are distributed globally from its Hikone Factory in Shiga Prefecture through customers’ equipment, contributing to comfortable lifestyles around the world.
