High-Performance Single-Passage Rotary Union Alternatives for Air, Hydraulic Oil & Vacuum

DANN Hydraulic is a professional rotary union manufacturer in China, supplying compatible replacement solutions for Deublin® and other international rotary union brands.

Our Deublin 2200 Series Rotary Union replacements are developed for industrial applications requiring reliable transfer of compressed air, hydraulic oil, vacuum, and compatible industrial media between stationary supply lines and rotating equipment.

Designed for maintenance replacement, machinery manufacturing, and OEM projects, our 2200 Series alternatives focus on stable sealing, low operating torque, accurate connection matching, precision machining, and dependable industrial operation.

We support individual model replacement as well as customized rotary union development based on drawings, samples, and actual machine operating conditions.

About the Deublin 2200 Series Rotary Union

The Deublin 2200 Series is primarily a single-passage / monoflow rotary union family used for pneumatic and related industrial fluid-transfer applications.

Its function is to transfer media from a stationary supply into a rotating shaft or machine component while maintaining a controlled seal during rotation.

Depending on the individual model and configuration, typical media can include:

• Compressed air
• Hydraulic oil
• Vacuum

The 2200 Series is particularly relevant to industrial systems where reliable pneumatic transfer, low torque, continuous rotation, and stable mechanical sealing are required.

Different 2200 models can use different rotor threads, supply connections, dimensions, flow capacities, pressure limits, and operating speeds. For this reason, DANN Hydraulic evaluates the exact original model and working conditions before recommending a replacement.

Key Features of Our 2200 Series Replacement Rotary Unions

Single-Passage Monoflow Design

The 2200 Series commonly uses a single-passage rotary union design, allowing one independent media circuit to pass through a rotating connection.

This configuration is suitable for:

• Compressed air supply
• Pneumatic actuation
• Hydraulic fluid transfer
• Vacuum systems
• General industrial rotating equipment

A straightforward internal flow path helps provide efficient media transfer while keeping the overall rotary union structure compact and practical.

Reliable Mechanical Sealing

Sealing performance is one of the most important factors affecting rotary union service life.

For compatible 2200 Series replacements, DANN Hydraulic evaluates:

• Operating media
• Pressure
• Rotation speed
• Temperature
• Duty cycle
• Seal contact surfaces
• Application environment

Our manufacturing process focuses on accurate seal positioning and controlled contact surfaces to help reduce premature leakage and unstable operation.

For demanding applications, sealing materials and internal configurations can be selected according to the actual working conditions.

Compressed Air Rotary Union Applications

Compressed air is one of the main applications associated with the Deublin 2200 Series.

A 2200 Series air rotary union replacement can provide continuous pneumatic media transfer to rotating equipment without twisting the stationary supply hose.

Typical applications may include:

• Pneumatic machinery
• Rotary actuators
• Industrial automation equipment
• Air-operated fixtures
• Rotating production equipment
• Pneumatic control systems

For applications involving continuous operation or elevated operating speed, proper model selection is particularly important.

Hydraulic Oil Applications

Certain 2200 Series configurations can also be used for hydraulic oil transfer.

Potential applications include:

• Hydraulic machinery
• Rotary fixtures
• Industrial actuating systems
• Hydraulic control equipment
• Rotating pressure circuits

Hydraulic applications should not be selected only according to external appearance.

Our engineering team evaluates:

• Hydraulic pressure
• Oil type
• Operating temperature
• Rotation speed
• Rotor connection
• Seal compatibility

before confirming a replacement configuration.

Vacuum Applications

Selected 2200 Series configurations can also support vacuum service.

Typical applications may include:

• Vacuum handling machinery
• Rotating vacuum fixtures
• Automated transfer systems
• Special-purpose industrial equipment

Vacuum performance depends strongly on sealing condition, installation accuracy, and the specific product configuration.

For vacuum replacement projects, we recommend providing the complete original model number and operating requirements.

Precision Manufacturing for Replacement Compatibility

A correct replacement rotary union requires more than a similar external shape.

Critical dimensions can include:

• Rotor thread
• Supply connection
• Housing diameter
• Overall length
• Rotor extension
• Port orientation
• Installation interface
• Internal flow diameter

DANN Hydraulic uses precision machining processes for important rotary union components.

Our manufacturing capability can include:

• CNC turning
• Precision thread machining
• Housing machining
• Rotor machining
• Seal surface finishing
• Dimensional inspection
• Assembly checking

Maintaining dimensional accuracy helps reduce installation problems and improves replacement consistency.

Low-Torque & Self-Supported Replacement Design

Depending on the specific 2200 configuration, the rotary union can use a self-supported structure with integrated bearings.

This type of construction helps support smooth rotation without requiring the machine piping to carry rotating loads.

For industrial users, this can provide practical benefits such as:

• Stable rotation
• Reduced load on supply hoses
• Easier installation
• Better alignment
• More predictable seal operation

Our replacement design is selected according to the structure and requirements of the original application.

Typical Industrial Applications

DANN Hydraulic 2200 Series compatible rotary unions may be considered for:

Industrial Pneumatic Equipment

Continuous compressed-air transfer into rotating machinery.

Automation Systems

Air, hydraulic oil, or vacuum transfer for rotating automation components.

Rotary Fixtures

Supplying media to rotating workholding or positioning equipment.

Production Machinery

Reliable fluid transfer for machines operating in repetitive production cycles.

Special-Purpose Equipment

Customized rotary interfaces for pneumatic, hydraulic, or vacuum functions.

The exact application suitability should always be verified using actual operating data.

OEM & Custom 2200 Series Rotary Union Solutions

As a China rotary union manufacturer, DANN Hydraulic supports both standard replacement products and customized industrial projects.

Connection Customization

Depending on the required model, we can evaluate:

• NPT threads
• BSP threads
• Metric threads
• UNS connections
• Right-hand or special thread configurations
• Customized rotor connections

Dimensional Matching

Customers can provide:

• Original rotary union model
• Technical drawing
• Existing sample
• Installation drawing
• Critical dimensions

Our team can evaluate the required replacement configuration.

Application-Based Engineering

For non-standard operating conditions, we can review:

• Media compatibility
• Pressure requirements
• Rotation speed
• Temperature
• Sealing arrangement
• Housing and rotor configuration

This is particularly useful when the original imported part has a long lead time, is difficult to source, or requires a customized alternative.
