Kadant Johnson Introduces New Rotary Union

Three Rivers, MI - Kadant Johnson Inc., a subsidiary of Kadant Inc., has developed a new line of rotary unions for water and thermal oil service. Designed from the ground up for tough applications, the new RX union features the latest technology in mechanical seal design including on-machine seal replacement for reduced downtime and a tungsten carbide counterseat for added toughness.

Capable of intermittent dry running, the RX union also includes an optional isolation barrier in the seal chamber to extend bearing life. Other features include stainless steel springs located outside the flow area, and an integral flange for rigid mounting and quick installation.

The RX union is available in sizes from 3/8" to 6" and in single- or dual-flow configurations. The union is rated up to 500 degrees F, 200 psig, and 3,500 RPM.
