Rotary Unions by Media and Application

Choosing the right rotary union depends on the type of media used and the specific requirements of your application. The following overview guides you directly to the most suitable product groups.

By Media

Air / Vacuum → Multiport Rotary Union Pneumatic
Hydraulic oil → Multiport Rotary Union Hydraulic
Water / Coolant / Steam → Multiport Rotary Union Water
 

By Function / Design

Single media circuits → Single Passage Rotary Union Standard
Multiple media simultaneously → Multiport Rotary Union Universal
Compact design → Multiport Rotary Union Compact
Heavy-duty / industrial use → Multiport Rotary Union Heavy-Duty

By Environment / Requirements

Hygienic & food applications → Single Passage Rotary Union Hygienic
Corrosive environments → Rotary Union Corrosion-Resistant
Through-bore integration → 1-Passage Rotary Union Through Bore

Rotary Unions in Combination with Slip Rings

Rotary unions can be combined with specially matched slip rings to enable the reliable transmission of not only media such as air, water, or hydraulic fluids, but also electrical power, signals, and data. These hybrid solutions are used when both media transfer and power or signal transmission are required simultaneously. By integrating both functions into a single unit, they provide a compact and space-saving solution, making them ideal for demanding applications with limited installation space – such as in industrial automation or mechanical engineering.
