摘要: Exchanger devices include a plurality of fixed exchange ducts and a rotating valve assembly for directing flow to and from the plurality of exchange ducts. Methods of exchanging pressure between fluid streams may include directing fluids through an exchange device and pressurizing a fluid in the plurality of exchange ducts of the exchanger device.

摘要: A centrifugal pump with a rotating impeller and a rotating diffuser. The diffuser may be rotated with a controlled speed to broaden the operational range of the pump. Such control may be done independently of the rotational speed of the impeller to tailor pump operation to a particular NPSH, efficiency, fluid flow or related requirement. In one preferred form, the impeller and diffuser are made to counter-rotate relative to one another, while the independent rotational speed of each may be provided by one or more motors, as well as a variable-speed transmission coupled to such motor or motors. Such a pump is optimized for specific speed operating ranges beneath those associated with axial flow pump configurations.
