Power Generation

Power generation plants vary greatly across the industry, from those fueled by coal or natural gas to those powered by nuclear, hydroelectric or geothermal energy. But though they operate differently, they still share a common goal: to meet the growing demand for energy in a responsible, efficient way. John Crane’s depth and breadth of applied engineering expertise, product innovation and reliability services help plants of all types increase uptime, reduce emissions and improve efficiency to achieve all of their goals.

We deliver proven mechanical seal technologies and services that improve power plant manufacturing performance through:

  • Increased operational reliability
  • Improved equipment uptime
  • Fewer maintenance interventions
  • Reduced seal water usage and energy consumption
  • Cost-effective environmental compliance
Tested Designs Proven Solutions

Tested Designs, Proven Solutions

For 100 years, John Crane has supported the power generation industry with reliability-tested solutions. Because John Crane mechanical seals operate in mission-critical power generation applications, our seal designs have been carefully tested under simulated in-plant conditions to ensure dependability in demanding situations. Our test centers can also perform chemical analyses and material compatibility evaluations specific to power generation applications.

All John Crane products are manufactured and certified in accordance with the most recent environmental, regulatory and technical standards around the world:

  • ANSI/ASME NQA-1
  • ANSI/ASME N45.2
  • ASME NCA-3800
  • CMTR
  • ISO 9000
  • GOST R
  • ATEX
  • ISO 9001
  • ISO 14001
  • 10 CFR 21
  • 10 CFR 50, Appendix B
  • ASME VIII div.1, PED(97/23/EC)
  • NORSOK

And our commitment to reliability doesn’t stop at quality components. With 200+ global rapid-response centers, we have one of the most reliable support and repair services in the world.
