ROTARY UNITS
SPECIAL VERSIONS
EXAMPLES
The stainless steel version of the rotary union series is particulary suitable for applications involving water / cooling water, hydraulics, or media such as trimethylaluminium and peroxide.
These rotary distributors are also used in the food industry.
For outdoor applications, as well as higher pressure and / or varying media, the stainless steel rotary units are the preferred choice.
Versions
The rotary unions are classified by the number of channels and the nominal size or connection thread:
Available number of channels: 1, 2, 4, 6 and 8
Connection sizes: M5 to G 3″ (see data sheets)
Material
Housing: Stainless steel
Spindle: Stainless steel
For direct contact with our experts regarding your required rotary distributor (DDF request), or alternatively, please complete the rotary unit project questionnaire.
Different Media
For applications involving different media, we recommend designating one channel as a leakage line.
General Information
The values specified in the data sheets represent the maximum achievable limits.
For use below 0°C or when multiple parameters operate close to their limit range, technical consultation is required.
