Over the past 100 years, rotating equipment technology has undergone a number of significant changes. Turbines, engines, compressors, pumps, gearboxes and generators have become more efficient and larger than ever. Single and multi-stage operations, as well as split and non-split variations, are now commonplace.

In most process operations, rotating equipment seldom warrants attention. A compressor, for example, works behind the scenes, often being taken for granted for reliable service; that is until regulatory, maintenance or competitive imperatives necessitate changes.

These rotating equipment changes have focused primarily on the need to comply with environmental regulations, increasing demands for higher temperatures, speeds and pressures, and complying with evolving design standards.

As rotating equipment has evolved, so too have the all-important mechanical seals that have kept the rotating equipment running. Seals are an essential element to any equipment with a rotating shaft that moves fluids. They prevent leaks, contain pressure and stop process fluid contaminations.

In this article, John Crane experts discuss how advancements in rotating equipment have been in lockstep with mechanical seal improvements, and how these changes have been in response to environmental, performance and regulatory issues.
