In various fields of industry, Pearl Rotary Joints have been successfully used under variety of service conditions covering a wide range of materials, pressures, temperatures and rotation speeds.
Pearl Rotary Joints are used for supplying/discharging compressed or decompressed (below atmospheric pressure) fluid/gas from a fixed piping to the rotary section of various machines with no leak. For example, they can be used when a heat transfer medium such as
- A floating seal ring provides good follow-up capability to the rotor seal face, resulting in stable seal performance.
- Due to low torque, a measure for preventing casing rotation is not required in many cases. (except for RXK)
