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
