Reduce data centre energy costs with high efficiency pumping systems

The Importance of Energy-Efficient Pumping in Data Centres
Cooling systems account for a significant portion of a data centre’s total energy consumption. With the increasing demand for sustainable and cost-effective operations, improving pump efficiency is a key strategy for reducing energy costs. By selecting the right pump technology, optimizing flow rates, and leveraging modern energy-saving features, data centres can achieve lower operating expenses, improved cooling performance, and reduced carbon emissions.

How Crest Pumps’ AVF-C Sealless pumps Reduce Energy Consumption
The Crest Pumps AVF-C mag drive canned motor pump is specifically designed for energy-efficient fluid handling in data centre cooling systems. Key features that contribute to cost savings include:
•    IE5 Equivalent Motor Efficiency – One of the highest efficiency ratings available, reducing power losses and optimizing energy use.
•    Minimum Efficiency Index (MEI > 0.7) – Exceeding Europe’s toughest energy performance standards and ensuring superior hydraulic performance plus minimal energy waste.
•    Variable Frequency Drive (VFD) Integration – Adjusts pump speed based on real-time cooling demand, preventing unnecessary energy consumption.
•    Sealless, Leak-Free Design – The AVF-C’s magnetically driven canned motor eliminates mechanical seals, reducing maintenance costs, unplanned downtime and preventing energy losses from leaks.
•    Compact Footprint – Designed for tight data centre environments, allowing for seamless integration without excessive space or installation requirements.
By incorporating the AVF-C magnetic drive canned motor pumps into cooling systems, data centres benefit from consistent energy savings, reduced downtime, and enhanced long-term sustainability.

Key Strategies to Optimize Pumping Efficiency
1. Implement Variable Speed Pumping
Traditional fixed-speed pumps run at a constant output, leading to wasted energy during periods of low cooling demand. By utilizing variable frequency drives (VFDs)—as seen in the AVF-C range—pumps can dynamically adjust to cooling needs, optimizing efficiency and lowering energy costs.
2. Correctly Sizing the Pump for Cooling Demand
Oversized pumps lead to unnecessary energy consumption, while undersized pumps struggle to maintain adequate cooling. The ideal pump selection depends on flow rate, pressure requirements, and overall cooling load. Using pumps like the AVF-C, which offer high efficiency across variable loads, ensures optimal energy usage.
3. Improve System Design with Low-Resistance Piping
Appropriately sized pipework whilst minimizing bends, restrictions, and long piping runs reduces pressure losses, allowing pumps to operate more efficiently. Properly designed systems with the correct pipework sizes for the flow velocities will prevent excessive strain on pumps, further reducing energy consumption.
4. Perform Regular Maintenance & Monitoring
Even the most efficient pumps can lose performance due to wear, clogging, or scaling. Advanced monitoring systems integrated with smart pumps provide real-time diagnostics, ensuring performance stays at peak levels. With magnetically driven technology, the AVF-C eliminates traditional wear points, reducing the need for frequent maintenance.
5. Transition to High-Efficiency, Low-Carbon Pumps
Upgrading outdated pumps to modern, high-efficiency alternatives can significantly cut operational costs. The AVF-C is designed to meet the growing need for low-energy, sustainable cooling solutions, making it an ideal choice for data centres focused on reducing their carbon footprint. (Crest Assoma can also provide you with the carbon footprint of the pumps supplied).

Energy efficiency is no longer just an option—it’s a necessity for data centres looking to cut costs and enhance sustainability. By integrating high-performance, VFD-enabled pumps like Crest Assoma AVF-C mag drive canned motor pump, facilities can achieve substantial energy savings, improved reliability, and long-term environmental benefits. With its industry leading efficiency, sealless design, and adaptability to real-time cooling needs, the AVF-C is a leading solution for next-generation data centre cooling.
