Dry gas seals have become essential components in centrifugal compressors across applications
John Crane, a global leader in flow-control technologies and an innovator in solutions for rotating equipment, and a business of Smiths Group, is marking 50 years since a revolutionary gas compression sealing, a technology that continues to play a critical role in major industrial operations across the Middle East.
While pioneering work on non-contacting spiral-groove technology began in 1968, and the first commercial installation was achieved in 1975, it was the introduction of the Type 28 dry gas seal in 1976 that created a true turning point for the industry, setting a new global benchmark for sealing performance, safety and efficiency.
Since then, dry gas seals have become essential components in centrifugal compressors across applications such as oil and gas, petrochemicals, power generation and, increasingly, hydrogen and carbon-capture applications.
Prioritising decarbonization
With the UAE advancing its Net Zero by 2050 goals and prioritising decarbonisation across the energy sector, reducing emissions and improving efficiency has become a key focus for operators, making sustainability a defining element of sealing technology.
Today, John Crane’s dry gas seals support a global installed base numbering in the thousands, backed by over 200 manufacturing, sales and service centres, including 12 turbo service centres worldwide.
This combination of technology leadership, global reach and on-site expertise continues to support customers’ operational reliability, environmental performance and safety goals.
“Dry gas seals transformed compressor reliability and set a new industry standard in 1976. Our 50-year anniversary not only celebrates a milestone in engineering innovation but also recognises the continued dedication of our global teams and the customers who have trusted our technology for decades. We remain committed to advancing sealing solutions that support reliability, efficiency and the future of sustainable energy,” affirmed Rubén Álvarez, President, John Crane.
