Figure 1: Isometric view of the Flowserve FLEX™
The Flowserve FLEX™ is an isobaric energy recovery device designed for reverse osmosis
seawater desalination applications. It takes the energy of a high-pressure fluid waste stream
and transfers the pressure energy to a low-pressure fluid supply stream. The simple design does
not require any external power, has only one moving part, and uses corrosion-proof materials for
high reliability and long life.
