Copper single bidirectional high speed high pressure high temperature pneumatic cooling water rotary joint
Water rotary joints are divided into unidirectional rotary joints and two-way rotary joints. Bidirectional flow rotary joints are divided into bidirectional flow inner pipe fixed rotary joint and bidirectional flow inner pipe rotary joint.
If the outer pipe of the water rotary joint is flanged connected to the journal of the equipment, the suffix F is added, such as HS-XF40-20, HS-GF40-20, where 40mm refers to the nominal diameter of the outer pipe of the rotary joint is 40mm. 20mm means that the nominal diameter of the inner pipe of the rotary joint is 20mm.
The outer pipe of the water rotary joint and the equipment journal are threaded without suffix, such as HS-X40-20, HS-G40-20, but the rotation direction of the outer pipe of the water rotary joint should be opposite to the rotation direction of the equipment drum, so that the thread is tighter and tighter

Can your standard rotary unions be modified to meet the requirements of my application?
We can modify our standard rotary unions to fit your needs. Custom modifications to our standard products are quite common and easier than you may think. Modifications include changes to housing / shaft dimensions and materials, seal types, mounting configurations, connection sizes and types, and flow passage configurations. For more information see Standard Rotary Union Modifications.
Do you offer replacement seals and/or bearings for rebuilding your rotary unions?
Yes, seal and bearing kits are available for our rotary union products for on-location rebuilding and repair. Contact us to Get Started.
Can I use a different media than what is listed on your site?
Fuxuan products are only recommended for use with the specific media types listed. This ensures proper compatibility with all components; shaft / housing, bearings and seals.
How do I install/mount my rotary union into my equipment?
CAUTION: FUXUAN does not recommend mounting the rotary union with both the shaft & housing components solidly bolted into place. One of the two components should be mounted in a manner that allows for some movement in the event of misalignment. Using only the supply lines or hoses to fix the stationary component in place is also not recommended. An anti-rotation arm that attaches to the stationary part of the rotating union assembly and rests against part of the equipment framework is recommended.
What is the life expectancy of a rotary union?
The life expectancy of a rotary union varies widely depending on many application variables: media type, pressure, rotational speed, duty cycle, temperature, and more. If you need further assistance contact a member of our Sales Support Team.
Is there a quantity price break if I order multiple units?
To discuss quantity price breaks, contact a member of our Sales Support Team.
Which part of the rotary union stays stationary and which part rotates?
Functionally it makes no difference whether the shaft or the housing rotates. It is all dependent on how the assembly is mounted and installed on your machine or equipment.
