A rotary machine such as a pump or turbine has a casing defining a space therein. A fluid channel is formed in the casing and has a plurality of first channel portions fluidically coupled a plurality of second channel portions. The first and second channel portions are separated by the space. A rotor is rotatably coupled within the casing and within the space. The rotor has a plurality of apertures therethrough positioned within the space. The apertures are adjacent to the channel to coupled the first channel portions to the second channel portions.
