  • Improving the efficiency of a jet pump using an

    Jet pumps are usually less efficient than other pumping devices and require a source of high-pressure fluid operation. This considerably limits their range of application. Jet pumps are primarily used to produce and maintain a vacuum by removing vapors from a closed system. In this service, they are usually called “ejectors.”
