Fluid Rotary Unions

Fluid Rotary Unions Overview

Moog's fluid rotary unions are currently used around the world to ensure reliable transmission of life support, process, power and control fluids. Currently, fluid rotary unions rated for pressures up to 15,000 PSI (1000 bar) are available. Seals are selected based on chemical compatibility, design pressure, design temperature, required service life and acceptable leakage rate. Leak collection can be supplied when required for environmental or personnel safety. Fluid rotary unions can be combined with our electrical slip rings and fiber optic rotary joints.

Options

  • Customized mounting and drive configurations
  • Customized materials to satisfy weight, chemical compatibility and other requirements
  • Customized port configurations
  • Hard coating, standard and high pressure FRU, cam be selected for improved abrasion resistance and extended seal life
  • Leakage detection and collection ports (drain to tank)
  • Optional hollow bore
