Type R.S. – Double Flow (Rotary Center Tube)
Fitted with an adapter suitable for a rotating center tube which must be located and driven by the machine. The center tube – provided only if ordered – rotates in a bush. Flow can pass in through the center tube with the return through the annulus or be reversed. The center tube “sealing” system allows for a slight internal leakage between the supply and return lines. If these fluids must not mix, alternate designs are available.
