Rotary Unions are self-contained and self-supporting rotary seals used to transfer fluids such as steam, water air or oil, to and from rotating machinery.

Standard units are of steel and iron construction with specials available in, for example, stainless steel and nickel alloys for chemically aggresive fluids or food quality applications.

The range of standard models in three basic types for single or dual flow are available with a choice of ball bearings for temperatures up to 160 degrees celsius and with plain cylindrical carbon bearings for temperatures of 100 degrees celsius up to 300 degrees celsius. Pressure range is 70 bar with rotational speeds up to 5000 rpm. In many instances it is possible to exceed these conditions after first consulting the Filton technical department for advice.

This Rotary Union is fitted with an adaptor suitable for double flow with a stationary centre tube. This provides flow areas through the centre tube and annulus. The centre tube is fixed to the Rotary Union by the means of a screw thread. Flow can pass in through the centre tube and return through the annulus or be reversed.

This Rotary Union is fitted with an elbow suitable for double flow with a stationary centre tube. This provides flow areas through the centre tube and annulus. The centre tube is fixed to the Rotary Union by the means of a screw thread. Flow can pass in through the centre tube and return through the annulus or be reversed.

* These parts rotate with the machine shaft.
