  • Reducing bearing load in a regenerative turbine pump
    Patent number: 11125234
    Abstract: A regenerative turbine impeller includes a first side and a second side. An impeller housing surrounds the regenerative turbine impeller. The impeller housing includes a seal separating the first side and the second side of the regenerative turbine impeller. A first fluid inlet is fluidically coupled to the first side of the regenerative turbine impeller. A first fluid outlet is fluidically coupled to the first side of the regenerative turbine impeller. A second fluid inlet is fluidically coupled to the second side of the regenerative turbine impeller. A second fluid outlet is fluidically coupled to the second side of the regenerative turbine impeller.
