  • Pump system for gas entrainment
    Patent number: 11131173
    Abstract: A pump system includes a centrifugal pump having an impeller, a first inlet arranged to receive a first flow of liquid, a second inlet arranged to receive a flow of gas at a first pressure, the gas being soluble in the liquid, and an outlet arranged to discharge a second flow of liquid that contains the flow of gas solubilized therein. An injection pump has an inlet arranged to receive the second flow of liquid. The injection pump is operable to increase the pressure of the second flow of liquid to produce a high-pressure flow of liquid, and includes a discharge arranged to discharge the high-pressure flow of liquid.
