4″ CBN/BE UNION Left
Type B.E. – Single Flow
A single flow union suitable for transferring fluid in to or out of rotating machines.
The rotary C.B.N. union is a self-contained, self-supporting rotary seal for the leak-proof transfer of fluids such as steam, water, air and oil to and from rotating machine shafts. The type of rotary seal fitted to this model is a Filton® Bellows Seal containing a flexible stainless steel bellows which is self-adjusting, eliminating the maintenance common with conventional packed glands. Rotary sealing is created by relative rotation between extremely flat sealing faces held in contact by the spring characteristics of the bellows combined with an additional sealing force created by the pressure of the fluid passing through the rotary union. The bearings fitted to the union are separate carbon thrust and journal bearings in which a hard chromed and ground spindle rotates.
