Rotating Unions For Water Applications
Product Announcement from KADANT
Kadant Johnson's line of rotary unions incorporates the latest technology in mechanical seal design for water and thermal oil service. The RX rotating union connects stationary piping to a rotating device. The high thrust load capability and carbon-to-silicon (or Tungsten) carbide seal package makes the RX run longer and with less maintenance requirements that other ball bearing designs. The RX features a barrier in the seal chamber to extend bearing life and a rotor and assembly plate made of stainless steel. The design also allows for on-machine seal replacement for reduced downtime.
Ranging in sizes 3/8" to 6", the RX is available in single- or dual-flow configurations. The union is rated up to 500 degrees F, 200 psig, and 3,500 RPM.
