Deublin 9000 Series Rotary Union Manufacturer | Steam & Hot Oil Rotary Union Solutions

Description

As a leading Deublin 9000 Series Rotary Union Manufacturer, we specialize in producing high-quality replacement rotary unions for steam, hot oil, water, coolant, air, and other industrial fluid transfer applications. Our factory focuses on delivering durable, precision-engineered rotary unions that provide reliable sealing performance, long service life, and excellent compatibility with original Deublin 9000 Series rotary unions.

With years of manufacturing experience, advanced CNC machining technology, and strong OEM/ODM capabilities, we supply cost-effective rotary union solutions to customers worldwide, including machinery manufacturers, steel mills, paper plants, textile factories, printing equipment suppliers, and industrial maintenance companies.

Our replacement rotary unions are engineered to meet demanding industrial operating conditions involving high temperature, high pressure, and continuous rotation.

What is the Deublin 9000 Series Rotary Union?

The Deublin 9000 Series rotary union is widely used in steam and hot oil transfer systems where rotating equipment requires continuous fluid flow between stationary piping and rotating components.

These rotary unions are commonly installed in:

• Paper drying cylinders
• Steel processing rollers
• Textile machinery
• Rubber and tire equipment
• Plastic extrusion lines
• Printing machinery
• Industrial heating systems

The 9000 Series is known for its high durability, leak-resistant sealing structure, and stable operation under harsh industrial conditions.

As a professional rotary union factory in China, we manufacture high-performance replacement models that provide equivalent functionality at a more competitive price.

Durable Construction for Long-Term Industrial Performance

Our Deublin 9000 Series rotary unions are manufactured using premium-grade materials to ensure exceptional durability and corrosion resistance.

Available housing materials include:

• Stainless steel rotary union bodies
• Carbon steel rotary unions
• Aluminum alloy rotary unions

These materials allow the unions to operate reliably in aggressive industrial environments involving:

• High-temperature steam
• Thermal oil circulation
• Continuous heavy-duty operation
• Moisture exposure
• Corrosive industrial fluids

The forged structure enhances mechanical strength and improves sealing stability during long-term operation.

The smooth surface treatment also improves wear resistance and reduces maintenance requirements.

Designed for Steam and Hot Oil Applications

Our steam rotary unions and hot oil rotary unions are specifically engineered for high-temperature fluid transfer systems.

Maximum Working Parameters

• Max Temperature: 232℃
• Max Pressure: 10 Bar
• Max Speed: 400 RPM

These operating capabilities make the product ideal for industries requiring stable heat transfer performance and continuous operation.

The high-temperature sealing system minimizes leakage while maintaining rotational flexibility and operational safety.

Wide Range of Thread Connection Options

To meet global industrial standards and equipment compatibility requirements, we offer multiple thread configurations, including:

• BSPP rotary union threads
• BSPT rotary union connections
• NPT threaded rotary unions
• Metric thread rotary unions

This flexibility allows customers to integrate the rotary unions into different piping systems and machinery platforms without complicated modifications.
