Description
The rotary P.B. union has been developed from the rotary R.E. union and utilizes the same well-proven and highly successful bellows seal and bearing system. The body is manufactured from de-zincification resistant brass which has advantages over conventional brass and the cast iron adapter of the rotary R.E. union, especially for water cooling applications.

Variations of the Stationary Adapter End
There are three variations available:

1) Type B.E. - Single Flow
A single flow union suitable for transferring fluid in to or out of rotating machines. The body is fitted with a plug at the outboard end which allows this type to be converted to a type S.T. or R.S. by using the appropriate elbow.

2) Type S.T. - Double Flow (Stationary Center Tube)
Fitted with an elbow suitable for double flow with a stationary center tube. This gives flow areas through the center tube and annulus. The center tube - provided only if ordered - is fixed to the union end by means of a screw thread (dimension “O”). Flow can pass in through the center tube and return through the annulus or be reversed. For steam applications, the center tube is curved to reach the condensate in the bottom of the cylinder. If the roll neck diameter to length ratio prevents the use of a curved tube, a syphon elbow can be specified instead. See the Accessory Section or contact us for more information about the options available.

3) Type R.S. - Double Flow (Rotary Center Tube)
Fitted with an elbow 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 labyrinth bush. Flow can pass in through the center tube and 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.
