MECHANICAL SEALS: John Crane Ltd Pins Its Faith On An Exclusive Up‐stream Pumping Mechanical Seal System

Abstract

Mechanical face seals were first introduced more than 70 years ago for sealing rotating shafts. As the technology of mechanical seals was improved over the years, they were found to offer significant advantages over the existing methods of sealing, for example, with soft packed glands. These benefits included reduced leakage and the elimination of the need for regular maintenance. Today mechanical seals are widely used on centrifugal pumps, compressors, and similar equipment for liquid/gas or gas/gas sealing.
