    Single flow rotary joints are used when it is needed to supply fluid into the rotary equipment from one side, and drain it from the other side. This means that fluid goes only in the single direction in the one unit. In this case two rotary joints are used for inlet and outlet of the process.

    Operating limits:

    p = 40 bar max
    t = 140°C
    v = 3000 RPM
