A pump includes a housing, a process stream input, a process stream output, a power stream inlet, and a rotor. The rotor comprises an impeller, a shroud, and a turbine. The impeller comprises fluid motive elements positioned about a central axis of the rotor and extending outward to the shroud. The turbine comprises runners formed on an outwardly facing surface of the shroud of the rotor. The shroud extends radially about the fluid motive elements of the impeller. The rotor is rotatably supported within the housing. The runners cause the rotor to rotate when the power stream flows through a fluid path impinging the runners thereby transferring energy from the flow of the power stream received through a power stream inlet into rotational energy of the fluid motive elements of the impeller to propel the process stream from a process stream input out a process stream output.

A high-speed hydrodynamic adjustable converter having a working chamber for forming a hydrodynamic working medium circuit wherein a pump wheel, a turbine wheel and a guide wheel are positioned in the working chamber. The working medium flows through the pump wheel centrifugally or centrifugally-diagonally; and the working medium flows through the turbine wheel centripetally or centripetally-diagonally. The inlet grate edge of the turbine wheel, with respect to an axis of rotation of the pump wheel and the turbine wheel, is positioned on a smaller or equal radius than an inlet grate edge of the pump wheel. The hydrodynamic converter has a first guide wheel in the working chamber before the pump wheel viewed in the direction of flow of the working medium, the guide wheel being arranged for purely centrifugal or diagonal-centrifugal throughflow of the working medium and is used to influence the power transmission.
