A deflector for a fluid mixing device includes a helical-shaped body having a first end, a second end, and a helical-shaped body between the first and the second ends. The helical body has two or more channels isolated from one another. In one non-limiting embodiment of the invention, the deflector is mounted in a cavity of a pipe between the first and second ends of the pipe to provide a mixing device having a first passageway connecting the first and the second ends of the pipe, and a second passageway connecting the first and the second ends of the pipe. The deflector in the pipe maintains the first and second passageways isolated from, and in a spaced relationship to, one another. Each of the passageways defines a hollow helical path as the distance from the first end toward the second end of the pipe increases.
