Type C.B./R.S. C.B./R.S.

Type C.B./R.S.

The Adaptor fitted to this Rotary (C.B.) Union is suitable for a rotating centre tube, which must be located and driven by the machine. Centres tubes are only provided if ordered.

The centre tube rotates in a bush. The centres tube “sealing” system allows a slight internal leakage between the supply and return lines. If these fluids must not mix then an alternative design can be provided. Please ask our Technical Department.

Flow can pass through the centre tube with the return through the annulus or be reversed.
