Deublin Rotating Union Technical Superiority: Built for Extreme Conditions

Deublin rotating unions are designed to address the toughest challenges in fluid and gas transfer systems. Key technical attributes include:

High-Pressure and Temperature Resistance

Pressure Range: From vacuum applications (-13.75 psi) to ultra-high pressure (6,530 psi for hydraulic systems), Deublin unions adapt to diverse operational demands.
Temperature Tolerance: Withstand temperatures from -20°C to +230°C, making them ideal for steam, hot oil, and coolant systems.

Multi-Passage Design

Deublin’s Deu-Plex series supports dual-channel configurations, enabling simultaneous transmission of air, hydraulic fluids, or vacuum without cross-contamination56. For complex systems, models like the 1379 and 1479 offer up to 4 independent media channels.

Precision Engineering

Balanced mechanical seals (e.g., carbon graphite/ceramic or tungsten carbide/ceramic combinations) ensure zero leakage even at speeds up to 22,000 RPM for coolant applications.
Low-torque designs reduce energy consumption while self-lubricating bearings minimize maintenance needs.

High-performance Deublin Rotating Union designed for harsh industrial environments, ensuring zero leakage and long life.

Versatile Media Handling

Deublin Rotating Union can accommodate a wide range of media including water, steam, hydraulic fluids, and compressed air. This versatility makes them ideal for diverse applications from machine tools to wind energy systems.

High-Pressure Capabilities

Many models are designed to operate under high pressures, with some series capable of handling pressures up to 210 bar (approximately 3,000 psi). This allows them to perform effectively in demanding environments.

Speed and Efficiency

With maximum rotational speeds reaching up to 20,000 RPM in certain models, our Unions enhance operational efficiency by allowing faster machining processes while maintaining optimal cooling& lubrication.

Durable Construction

The Rotating Union is built with high-quality materials such as stainless steel and brass, featuring precision-engineered mechanical seals that ensure leak-proof operation even under extreme conditions. Options for silicon carbide seals are available for applications involving abrasive or corrosive media.
