Rotary Union For Multiple Media

Description

Our Rotary Unions for Multiple Media are designed for applications requiring the simultaneous transfer of different media—such as air, water, hydraulic oil, coolant, and vacuum—through a single rotating interface. Engineered for reliability and efficiency, these multi-passage rotary unions ensure continuous, leak-free media transfer between stationary and rotating components in demanding industrial environments.

The housing is precision-machined from high-strength aluminum alloy or stainless steel, while advanced sealing technologies prevent cross-contamination between media passages. Whether you operate in automation, packaging, robotics, or CNC machining, these rotary unions ensure seamless performance and a long service life.

How It Works

A Rotary Union for Multiple Media allows different fluids or gases to flow through independent channels while rotating continuously. Each channel is separated by precision-engineered seals, preventing any cross-leakage. The rotary union’s rotor connects to the rotating component, while the stator connects to the stationary supply lines.

This design makes it possible to transfer multiple media simultaneously, such as:

• Hydraulic oil for actuation

• Air for pneumatic control

• Coolant for temperature regulation

• Vacuum or signal lines for automation feedback

Key Features of Rotary Union for Multiple Media

Multi-Channel Design for Versatile Media Transfer

This rotary union is engineered with independent flow passages that allow simultaneous transfer of multiple media types—such as air, water, oil, and hydraulic fluid—without cross-contamination. Ideal for complex systems requiring precise media segregation.

High-Performance Sealing Technology

Equipped with advanced mechanical seals or specialized elastomer seals (like Viton or PTFE), it ensures leak-free operation even under high pressure and temperature variations. The sealing system maintains consistent performance during continuous rotation.

Durable Construction for Industrial Environments

The housing is made of corrosion-resistant stainless steel or anodized aluminum (as shown in the image), offering excellent protection against wear, rust, and chemical attack. Perfect for demanding applications in manufacturing, automation, and fluid handling.

Precision Bearings for Smooth Rotation

Built-in precision ball bearings reduce friction and torque, enabling stable and efficient operation at both high and low speeds. This ensures long service life and consistent rotation even under heavy load conditions.

Flexible Mounting Options

Available with threaded, flanged, or custom mounting interfaces to meet diverse installation requirements. The compact structure allows easy integration into confined or multi-axis machinery setups.

Support for Various Operating Conditions

Designed to handle high pressure (up to 30 MPa depending on model) and a wide temperature range (–30°C to +200°C), making it suitable for both standard and extreme industrial environments.

Independent Flow Path Isolation

Each passage is fully isolated by internal barriers, ensuring that different fluids or gases do not mix—ideal for systems involving coolant, air, and oil circulation simultaneously.

Low Maintenance and Long Service Life

The combination of robust materials, optimized flow channels, and precision components minimizes wear and extends maintenance intervals, reducing downtime and operational costs.

Customizable Configurations

Available in 2-passage, 3-passage, 4-passage, or higher versions to match specific application requirements. Options include custom materials, port sizes, seal types, and pressure ratings.

Suitable for Multiple Industries

Commonly used in robotics, CNC machining, packaging machinery, textile equipment, and chemical processing systems where reliable multi-media transmission is essential.
