Abstract
A centrifugal oxygenator pump includes a bottom inlet into an impeller chamber, the bottom inlet having a venturi gas inlet for mixing gas with the in flowing liquid. The impeller chamber is of a frusto-conical shape within which is rotatably mounted a similarly shaped mismatched impeller, the impeller driving the liquid and gas mixture toward a toroidal outlet chamber and through an outlet to an outlet nozzle. The motor drives the impeller to attain a high specific speed so that an increased capacity and larger size oxygenator is provided with maximum efficiency and effectiveness.
