Types of pumps in data centre cooling - Crest Assoma AVF-C

Written by James Dashwood | April 2025

“AVF-C pumps redefine efficiency benchmarks…actively pushing efficiency boundaries and yielding an improved power usage effectiveness (PUE). Proven in our server cooling systems, these pumps enhance performance while significantly reducing energy consumption.” – Dr Justin Wu, Intel open IP Team


Maximise efficiency, minimise emissions.
The AVF-C magnetic drive canned motor pump is built to save you energy – with the highest motor efficiency (IE5 equivalent), highest pump efficiency (minimum efficiency index, MEI >0.7), and variable frequency drive, meaning the smallest carbon emissions sealless pump you can currently own. 
Canned motor pumps integrate the design of the electric motor and magnetic drive pumps into one. The stator of the motor directly drives the inner magnet of the pump, eliminating the motor rotor and the drive magnet. Like the magnetic drive pump, the magnetic flux between the stator and the inner magnet passes through the containment shell, allowing the pump to be hermetically sealed for leak-free operation.


Designed by Assoma Inc in Taiwan and assembled and supplied exclusively by Crest Pumps into the UK, all pumps in all materials of construction are UK stocked and ready for next day despatch to handle any application.


Where to use AVF-C magnetic drive canned motor pumps:
•    Moving any chemicals where leakage must be avoided or are harmful to the environment, including corrosive, toxic, or expensive!
•    Where process control is crucial.
   When looking to implement long-term energy saving.
•    Cleanroom locations or confined spaces.
   Environments with strict temperature and humidity control.


“We’ve seen a drastic reduction in maintenance issues, make[ing] it a hassle-free choice for our operations, freeing up our teams to focus on what they do best.” – Joyce Huang, Manz.

Everything’s reduced!
Because the AVF-C range is a fan less design, both heat and noise are significantly reduced compared to traditional mag drive pumps. And because of the canned motor, they are smaller and lighter weight, taking up less floor space to increase server density whilst becoming easier to manoeuvre for maintenance.

 

Revolutionising data centre cooling: Intel’s open IP immersion cooling
In the fast-paced data centre industry, achieving energy efficiency is a key goal due to the rising demand for computing power and energy costs. Immersion cooling emerges as a ground-breaking solution, cutting down environmental impact and expenses by efficiently managing heat through dielectric fluid immersion, a stark contrast to conventional cooling methods.


This approach not only slashes energy use and operational costs but also enhances overall efficiency. Immersion cooling represents a forward-thinking strategy to tackle the challenges of high energy consumption and carbon footprint in data centres, marking a significant shift towards more sustainable operations.


Introducing Intel’s open IP program
Intel's Open IP Program leads in advancing single-phase immersion cooling technology, enabling collaborative innovation for more efficient data centre cooling solutions. This program encourages the development of energy-saving techniques by sharing Intel's IP with a network of professionals.

The Assoma AVF-C pumps were approved for Intel's cooling system and chosen for their low energy consumption, compactness, and suitability for clean-room use. Exceeding Europe's top efficiency standards and contributing to reduced operational costs make them the ideal choice for data centres.
