湿封系统

With over 100 years’ experience in developing technologies that optimize rotating equipment performance, John Crane understands mechanical seals. We know that you need reliable seal performance to maximize process efficiencies while meeting production targets and constantly evolving, stringent operational requirements. Our expert engineers have designed a range of fluid control systems that create the optimal operating environment to enable the dependable performance you expect from a John Crane seal. No matter what the process fluid, from liquids to gases, cryogenic to boiling and abrasive to the purest finished product, our range of barrier fluid reservoirs, heat exchangers, abrasive separators and pump seal gas control panels support the most complete spectrum of industrial processes. Compliant with global industry codes such as API, ASME VIII and ASME B31.3, our systems can also be designed and built to meet regional specifications such as AD2000, ATEX, CE, PED, SELO and GOST.
