Rotary joints, also referred to as rotary unions, permit the flow of various media from fixed piping to rotating equipment. A considerable amount of production processes have a need for rotary joints, with a broad range of different specifications. Choosing the right rotary joint for your application is important to ensure reliability, long life, safety, and process efficiency.  

The most suitable rotary joint depends on the following operating criteria:

• Media
• Maximum temperature
• Maximum speed
• Maximum and minimum pressure
• Space requirements

If your application requires various media to flow through the rotary union simultaneously, a multi-passage rotary union is recommended. Learn more about the Kadant range of rotary joints and their applications.
