Flowserve releases new dry-running vacuum pump

Flowserve Corp’s new Sihi Boost UltraPLUS dry-running vacuum pump is designed to reduce cycle times for batch processes by up to 50% or more.

The Sihi Boost UltraPlus vacuum pump is the next evolution of Flowserve Sihi Boost pump systems, which were introduced in 2013. This new and improved pump design retains all the advantages of the original Sihi Boost pumps — including oil-free operation and full electronic synchronization — and cuts re-acceleration time up to 50%. These performance enhancements were made possible by cooling improvements, upgrading materials to withstand the highest load scenarios and a new gap distribution strategy.

The unit can provide a compression ratio (K0) of up to 100,000:1, which is exponentially higher than the rate of the highest-performing Roots-type blower (maximum 75:1).

“Sihi Boost UltraPLUS vacuum pumps raise the industry standard by delivering the fastest pump-down and cycle times available for load lock applications,” said Stefan Lähn, global product portfolio leader — vacuum pumps, compressors and systems for Flowserve. “By just changing the vacuum system, you can potentially double the output of your existing process equipment.”
