Power Industry

Rapid load variations, frequent stops and starts, and the highest temperatures, flows and pressures. Welcome to fluid motion and control in the power industry. These grueling applications are where Flowserve became a driving force in power generation. To appreciate our role, you needn’t look further than our pioneering work in nuclear power or the massive machines we’ve built for conventional steam plants. But that’s history. Today, we’re developing next generation solutions to meet the newest challenges, including concentrated solar, biomass and geothermal.

Series 80 / CPM

null

The Series 80 seal is one of Flowserve’s Heritage products that has a proven track record of performance. Built with premium materials, this Stationary designed, Hydraulically balanced seal succeeds in the most challenging applications.

Flowserve spun off the more popular sizes of the Series 80 and formed the CPM seal which allows us to compete with today’s low cost seal manufactures. The CPM line of seals are used for competitor change outs in general service applications.Compaired to other light duty seals, the CPM seal weights 30% more due to the heavy duty gland design. The flush port is also larger than most light duty seals making the CPM seal a better all-around choice.
