John Crane is a leading manufacturer of mechanical seals. They produce different seal solutions for a wide range of industrial and municipal pumping applications, including carbon captures and sequestration projects, natural gas compression, coal gasification, ethanol production, and fertilizer production. One of their uniquely specialized product categories is their dry gas seals.
With John Crane, you can choose from a comprehensive range of dry gas mechanical seals used in various industries. Dry gas seals for turbo compressors, centrifugal pump systems, steam turbines, vaporizing liquids, and other specific applications are ideal for John Crane products. They revolutionized the market when patenting the spiral groove technology in 1968—a design that is still a key component in many of their dry gas seals. As their technology and innovation continue to evolve, so do their dry gas seal designs.
Here are three of the key benefits of John Crane dry gas seals:
- Carbon Capture
Carbon capture has always been a significant challenge in the natural gas industry. John Crane has several case studies featured on their blog, describing how their dry gas seal solutions have greatly improved the large-scale carbon capture process for several key clients across numerous industries. Natural gas deposits can contain large amounts of carbon dioxide (CO2), Which must be removed before the gas is processed or sold. The carbons must also be stored and repurposed for other applications—a delicate process where John Crane seals have made a measurable difference.
- Carbon Storage
Once the carbon dioxide gases and other carbon elements have been removed from the raw natural gas deposits, they need to be effectively stored. Having a dependable dry gas seal solution is crucial. Allow John Crane comes mechanical seals to save the day: they prevent dry gas leaks and outside contaminants that can damage the integrity of the carbon gases being stored.
- Carbon Utilization
The stored carbons need to be utilized in other applications such as gas refinement and fertilizer production. John Crane dry gas seals have improved these processes for industrial system operators. The carbon gases can be transferred and distributed as needed without the risk of leaks, loss of pump system pressure or temperature-related equipment failures.
John Crane Dry Gas Seals
John Crane produces nine different dry gas mechanical seals with specific performance capabilities and technical characteristics for particular applications:
- Aura—The next generation of John Crane dry gas seals to reduce operational and transactional costs with a polymeric sealing device.
- Aura 120NS—This is a narrow-section version of the Aura dry gas seals that eliminates the need for oil lubrication and prevents methane entrapment.
- Type 28AT—A non-contacting as seal specifically for turbo compressors. This is John Crane’s original dry gas seal design that continues to evolve.
- Type 28XP—One of their most popular dry gas seals and a more advanced version of the Type 28AT.
- Type 28EXP—This is the non-contacting gas seal for the most challenging and extreme turbo compressor environments.
- Type 83—A separation seal with contacting technology. It features a dual-segmented carbon bushing that prevents the migration of bearing oil into the dry gas.
- Type 93FR—This specialized non-contacting separation seal is excellent for specific dry gas applications.
- Type 28ST—This is a non-contacting gas seal for steam turbines, featuring a rotating groove and high-temperature secondary seals to reduce steam leakage.
- Type 28VL—A non-contacting gas seal for vaporizing liquids. This seal utilizes spiral groove technology to vaporize process fluids at a controlled rate.
