D Type Dual Flow Rotary Unions Dual Channel Rotary Joint

Description

Dual Flow Rotary Unions Product Overview:
Dual Flow Rotary Unions are a cutting-edge solution engineered to handle two independent fluid paths in rotating systems, enabling simultaneous transfer of liquids, gases, or mixed media. Perfect for industries demanding multitasking efficiency, this rotary union eliminates the need for multiple units by delivering seamless, cross-contamination-free performance. Built for durability and precision, it’s the ultimate upgrade for complex machinery requiring dual-flow capabilities.

Key Features:
Dual Independent Flow Channels: Transfer two different media (e.g., air + water, oil + coolant) simultaneously through separate passages. Ideal for applications requiring synchronized operations without fluid mixing.
Robust D-Type Design: Compact, space-saving “D” profile ensures easy integration into tight spaces. High-strength materials (stainless steel, brass, or carbon steel) for corrosion resistance and longevity.
Zero Leakage Guarantee: Advanced multi-lip sealing technology and precision-machined components ensure leak-proof operation, even under extreme pressures and speeds.
High-Speed & High-Pressure Performance: Engineered to handle up to 3000 PSI and temperatures from -30°C to 250°C (-22°F to 482°F).Supports rotational speeds of up to 1500 RPM (customizable for higher demands).
Low-Friction Bearings: Premium ball bearings reduce wear, ensuring smooth rotation and extended service life.
Versatile Media Compatibility: Works with air, water, hydraulic oil, coolants, steam, and other industrial fluids.
Easy Maintenance & Modular Design: Quick-disconnect fittings and replaceable seals minimize downtime during servicing.

What is a D Type Rotary Unions?
A D Type Rotary Union is a mechanical device used to transfer fluid (including air, water, and hydraulic oil) from a stationary source to a rotating piece of machinery. They are engineered for durability and efficiency, making them suitable for industries requiring reliable operation under high pressure and angular movement.
What are the key features of D Type Rotary Unions?
Key features include high-pressure capability (up to 70 bar or approximately 1015 PSI), versatile media compatibility (air, water, hydraulic fluids), support for angular movement, compact design, and high rotational speed (up to 5000 RPM).
What are the common applications of D Type Rotary Unions?
Common applications include hydraulic and pneumatic systems, air-driven equipment (clutches and brakes), water transfer applications (car washes, irrigation), and various industries like agriculture, construction, and manufacturing. They are also utilized in printing machinery, food and beverage processing and textile manufacturing.
What is a Dual Flow Rotary Union?
A Dual Flow Rotary Union, like the D Type, allows for the simultaneous transfer of two distinct media. This design is beneficial in pneumatic and hydraulic systems, printing machinery (transferring inks and coolants), food and beverage processing (transferring liquids and gases), and textile manufacturing (maintaining water and lubricants in machines).
What are the advantages of using Dual Flow Rotary Unions?
Dual flow rotary unions enhance efficiency by eliminating the need for separate transfer systems, have a compact design suitable for limited spaces, minimize downtime by ensuring reliable fluid flow and can be customized for specific application requirements.
Which industries benefit from using D Type Rotary Unions?
A vast range of industries benefits, including agriculture, automotive, car washes, converting, corrugating, floor covering, machine tools, mining, oil & gas, paper, plastics, printing, renewable energy, steel, and textile.
What materials are used in D Type Rotary Unions?
Standard seals often consist of graphite and stainless steel. The housing is typically made from robust materials to ensure structural integrity in harsh industrial environments.
What should be considered when choosing a D Type Rotary Union?
Considerations should include application requirements, media type, installation configuration (end of shaft or around shaft), material compatibility, operating pressure and speed, and connection type.
What is the maximum operating pressure for a D Type Rotary Union?
D Type Rotary Unions can handle pressures up to 70 bar (approximately 1015 PSI)1. However, for pressure exceeding 60 bar (870 PSI), it is advised to consult with a technical team.
What brands offer D Type Rotary Unions or comparable products?
Girol offers D Type Rotary Unions for air and vacuum applications2. Deublin offers a range of rotary unions suitable for various media, including air and hydraulic oil, with designs for single and multiple passages.
