The RX rotary union uses a balanced seal with special ball bearing or optional tapered roller bearings to support the rotor. This rotary union incorporates the latest technology in mechanical seal design for water and thermal oil service. 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. All O-rings are fully captured in glands and seal-loading springs do not contact the process fluid. The RX features a barrier in the seal chamber to extend bearing life and a nipple and assembly plate made of stainless steel. Available in single- and dual-flow configurations and sizes from 3/8” to 6”, the RX rotary union is capable of operating up to 500° F (260° C), 150 psig (10 bar), and 750 RPM.
