Non-contact type 2800X sealing in non-turbo use
A new John Crane brochure describes the Type 2800X non-contacting dual seals, outlining their particular suitability to large-bore, non-turbo rotating equipment applications
* New technology from John Crane includes a wireless sensor for monitoring sealant system performance that will have many offshore industry applications.
This system will provide a cost-effective, real-time monitoring and alarm solution for such operating environment parameters as level, pressure and temperature.
This will enable problems to be identified at an early stage so that corrective action can be taken quickly, promoting extended seal life, increased uptime and reduced operating costs.

The system's remote mode of operation means it can be installed at a fraction of the price of a hard-wired system, and the secure, real-time data streaming ensures shorter decision-making periods.
Offshore applications are numerous for this John Crane wireless remote monitoring technology.
Traditional systems, used to monitor the condition of pumps and other rotating equipment, often require considerable manpower to collect, upload and analyse the data and may suffer from problems related to safety, data quality, reliability and labour costs.
The John Crane wireless condition monitoring technology will enable the data to be collected remotely, analysed rapidly and then presented to the system user exactly when it is required, so that decisions can be made and potential problems dealt with at a much earlier stage.
The system minimises manpower requirements, eliminates the need to collect data manually from hazardous locations, provides accurate and reliable information and has the ability to deliver significant financial benefits to offshore industry customers.
* Oil Plus has formed an integral part of the John Crane specialist solutions offering.
During its 29-year history the specialist technical expertise provided has brought benefits to some of the largest names in the global oil and gas industry, being used on over 870 international oilfield projects.
Specialist skills in many different areas are offered, including water injection, produced water treatment, separation processes, corrosion control, production chemistry and produced water handling.
Working in partnership with its clients, Oil Plus undertakes research and development projects and provides analysis, training and operational support services.
* The John Crane reliability management division, Performance Plus, was also present on the John Crane stand in the specialist solutions area.
This division uses a unique combination of specialist management experience and advanced technical expertise to devise and implement solutions that deliver significantly improved plant performance, increased uptime and reduced operating costs to its customers.
By aligning its own goals to those of the customer and then designing a genuinely bespoke solution, Performance Plus has built an impressive track record of success in helping its customers to extend the operating life of their major assets.
Operating in-line with a unique business model also allows Performance Plus to achieve this without the need for those customers to incur additional capital investment or financial risk.
* Key to the John Crane development of such enabling specialist solutions for offshore applications is its history of consistently pushing the boundaries of technology.
This approach is evident in the John Crane range of products designed for turbomachinery applications.
The Type 28 dry-running gas-lubricated compressor seals have been the industry standard for gas-handling turbomachinery operations since the early 1970s.
Thanks to the John Crane patented spiral groove pattern their non-contacting operation minimises wear problems, eliminates seal oil contamination and reduces maintenance costs and downtime.
The single, double and tandem cartridge seals available are capable of handling a wide variety of applications in the gas collection/transmission, refining, chemical and petrochemical processing industries.
The newest addition to the Type 28 family, the high pressure dry gas seal, will be on show, in addition to the seal supplied to the largest ever Liquefied Natural Gas (LNG) compressor which has a shaft size of 350mm.
John Crane has nearly 200 high pressure seals operating in the field and this new version of the Type 28EXP seal will enable operation way beyond existing limits.
John Crane also leads the field in the development of large diameter seals for LNG applications and has supplied seals to the vast majority of the LNG plants built around the world over the past three years.
* The new range of John Crane H-series power transmission couplings are based on their Metastream high performance couplings that have been proven on many turbomachinery applications over the past 20 years.
By redesigning the H-series products right from the basics John Crane has been able to extend the boundaries and deliver a new breed of lightweight, high performance couplings suitable for both today's turbomachinery applications, and those of tomorrow.
John Crane is completing a GBP5 million investment programme designed to extend its leadership in this field, which includes the recent opening of the world's most advanced dry gas seal test facility.
John Crane turbomachinery experts were present on the stand during the show to describe these latest developments, including the Type 82 and Type 83 barrier seal which uses a unique double sealing dam system to provide superior oil separation performance.
* In addition to the newest Turbomachinery Solutions for offshore applications, John Crane also reaffirmed its position as the expert in sealing solutions by showing Active Lift Technology (ALT) which uses proven, state-of-the-art gas seal principles to produce the first ever wet seals with the life expectancy more typical of a gas seal.
John Crane ALT seals are guaranteed to run for at least two years, even in the most difficult offshore duties, and offer a proven life expectancy of three years on produced water applications.
Developed from their unique upstream pumping expertise, the John Crane ALT delivers a rare combination of greatly increased life expectancy, ultra-high reliability, extremely low maintenance requirements and reduced costs.
It has already proven its abilities on offshore applications handling aggressive, high solid-content fluids such as produced waters by providing a highly effective fit-and-forget alternative to the traditional double seal arrangement.
Visitors were also able to view some John Crane Type 8600 high duty seals.
These provide a new dimension in mechanical sealing reliability for demanding applications such as sea water injection and main oil line pumps.
They combine all the benefits that John Crane high duty seals have demonstrated over the last 30 years with the company's latest advances in materials and surface texturing techniques.
The net result is the most advanced high-duty seal yet, capable of operating at over 200 bar and speeds in excess of 50m/s.
By offering the highest degree of reliability in the most extreme operating conditions they provide the ever-increasing levels of pump availability required by today's operators and have been developed to operate over a wide range of applications without the need for special analysis or design changes.
