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
- Can be used in a high-temperature range (max. 180℃).
(Quasi-standard products that can be used at 180℃ or higher are available.) - As a carbon bearing is used, greasing is not required.
- Low mechanical seal wear allows stable operation for a long time.
