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 regenerative pump includes a housing defining a cavity having a fluid inlet arrangement and fluid outlet arrangement, and a channel having an open volume extending between the fluid inlet arrangement and the fluid outlet arrangement. A rotatable shaft extends into the housing. An impeller is mounted to the shaft within the cavity and has a plurality of vanes spaced circumferentially around the axis and opening into the channel. An arm arrangement at least partially defines walls of the channel. The arm arrangement is radially movable to vary the volume of the channel. Enlarging the volume of the channel inhibits regenerative circulatory flow during pumping and limits the pressure generated.

A scavenging centrifugal baffle pump. The scavenging centrifugal baffle pump includes a main pump, which includes a pump housing. The scavenging centrifugal baffle pump further includes a baffle connected to the main pump housing and defines defining an interior volume. The scavenging centrifugal baffle pump also includes a gear coupled to the main pump at least partially located in the interior volume of the baffle, a reservoir defined in the interior volume of the baffle, an inlet defined in the baffle adjacent to the reservoir and an elongate passage defined by the baffle.

A convector for cooling a microprocessor includes a volute-shaped housing, a stator, and a rotor, and can be mounted to a CPU board of a computing device for thermal coupling with the microprocessor. The volute-shaped housing of the convector encapsulates the stator and the rotor, and has a radially outer casing which defines a single exit port for guiding a fluid out of the housing. The stator has a plurality of plates configured to conduct heat. The rotor has a plurality of disks and a shaft extending longitudinally along the housing. Together, the housing, the stator, and the rotor define a spiral flow path through the volute-shaped housing, in both radially outward and longitudinal directions, to the single exit port. A motor may be provided to impart rotational motion to the rotor.
