SANYO DENKI Launches San Ace Pump for Liquid Cooling Systems with High Flow, Low Power Consumption, and Long Life

SANYO DENKI Launches San Ace Pump for Liquid Cooling Systems: High Flow, Low Power Consumption, and Long Life for AI Data Centers

As AI Power Density Increases, Liquid Cooling Is Becoming Essential

The rapid growth of generative AI, large language models (LLMs), high-performance computing (HPC), and hyperscale data centers is driving server power densities to unprecedented levels.

Traditional air-cooling solutions are increasingly reaching their thermal limits, especially in applications such as:

• AI GPU servers

• High-density data center racks

• Liquid-cooled server systems

• Edge computing facilities

• High-performance computing platforms

As a result, liquid cooling technologies are becoming a critical part of next-generation thermal management strategies.

To address these growing cooling demands, SANYO DENKI officially launched the San Ace Pump on June 2, 2026. Designed specifically for liquid cooling systems, the new pump delivers high flow, low power consumption, and long service life to support the cooling requirements of modern AI infrastructure and data centers.

Introducing the New San Ace Pump

The San Ace Pump is a liquid cooling circulation pump engineered for high-performance cooling systems.

Key design features include:

• Non-self-priming centrifugal pump design

• 48V DC operation

• High-flow performance

• High-head capability

• Long-life architecture

The pump is designed to enhance coolant circulation efficiency in liquid cooling systems used for AI servers, data center equipment, and advanced computing platforms.

Key Features

1. High Flow and High Head Performance

As server thermal loads continue to rise, coolant circulation capacity becomes increasingly important.

The San Ace Pump delivers:

Maximum Flow Rate

160 L/min

(at a head of 6 m(H₂O))

Maximum Head

32 m(H₂O)

This combination of high flow and high head helps improve:

• Cold plate cooling efficiency

• Coolant Distribution Unit (CDU) performance

• Rack-level liquid cooling systems

• AI server thermal management

The result is greater cooling capacity for high-density computing environments.

2. High Efficiency and Lower Energy Consumption

Energy efficiency is one of the most important considerations for modern data centers.

Cooling infrastructure can account for a significant portion of overall facility power consumption.

Despite its high-performance output, the San Ace Pump maintains excellent efficiency.

Power Consumption at Maximum Flow

648 W

Benefits include:

• Reduced cooling system energy usage

• Improved data center energy efficiency

• Lower operational costs

• Support for sustainable and green data center initiatives

For large AI facilities operating hundreds or thousands of cooling loops, efficiency improvements can have a significant impact on total operating expenses.

3. Long Service Life for Continuous Operation

Reliability is critical in mission-critical computing environments.

A pump failure can affect:

• AI server availability

• Training workloads

• Cooling system stability

• Data center uptime

The San Ace Pump offers:

Expected Life

70,000 Hours

Equivalent to approximately:

8 Years of Continuous Operation

Test conditions:

• Water as the working fluid

• Rated voltage

• Continuous operation at maximum flow

• Ambient temperature: 45°C

• Fluid temperature: 45°C

The long service life helps reduce:

• Maintenance frequency

• Downtime risk

• Spare parts inventory requirements

• Total cost of ownership (TCO)

Why Liquid Cooling Pumps Are Becoming More Important

Rising Thermal Loads in AI Infrastructure

The thermal design power (TDP) of modern computing hardware continues to increase dramatically.

As thermal loads rise, traditional air cooling faces challenges such as:

• Airflow limitations

• Higher noise levels

• Increased energy consumption

• Reduced cooling efficiency

Liquid cooling offers several advantages:

• Higher heat transfer efficiency

• Lower PUE (Power Usage Effectiveness)

• Greater rack density

• Improved thermal stability

At the heart of every liquid cooling system is a reliable coolant circulation pump.

Typical Applications
