MEDIUM

In industrial machinery, the type of medium being transferred plays a critical role in determining the design and performance of a rotary union. Different media—such as compressed air, water, steam, thermal oil, or hydraulic fluid—require specific sealing materials, internal structures, and pressure tolerances to ensure safe and reliable operation.

Our company specializes in designing and manufacturing rotary unions optimized for different industrial media, ensuring stable fluid transfer between stationary pipelines and rotating equipment.

As a professional manufacturer exporting rotary unions worldwide, we provide high-precision rotary joint solutions that match or replace many leading international products while offering competitive pricing and flexible customization.

This category page organizes our rotary union products according to working medium, helping engineers, maintenance teams, and procurement managers quickly identify the most suitable solution for their application.

Our Rotary Union Solutions by Medium

We provide rotary unions specifically engineered to handle a wide variety of industrial media. Below are the main categories available on this page.

Air/Pneumatic Rotary Unions

We engineer our air rotary unions to transfer compressed air or vacuum into rotating components efficiently. These rotary unions are essential for modern industrial automation and pneumatic control systems.

Water and Coolant Rotary Unions

We design our water rotary unions to supply cooling water or coolant to rotating equipment reliably.

Steam Rotary Unions

Steam rotary unions handle high-temperature and high-pressure steam transfer in demanding industrial environments. These rotary unions require specialized seals and materials capable of handling extreme temperatures and thermal expansion.

Thermal Oil Rotary Unions

Thermal oil rotary unions allow safe transfer of high-temperature heat transfer fluids used in industrial heating processes. Their design ensures stable performance under high temperatures and continuous thermal cycling.

Hydraulic Oil Rotary Unions

Our hydraulic rotary unions power heavy-duty machinery by delivering high-pressure oil through rotating interfaces. These models are engineered to withstand high-pressure loads while maintaining leak-free operation.

Key Factors When Selecting a Rotary Union by Medium

Choosing the right rotary union based on the working medium requires evaluating several important parameters.

  • Temperature Compatibility
  • Pressure Requirements
  • Seal Material Compatibility
  • Rotational Speed

High-speed equipment requires rotary unions with precision bearings and optimized balancing to ensure stable operation.
