The Q12P01-3084-A6503 is an integrated fluid rotary union designed for the simultaneous rotary supply of multiple media. It features a black anodized aluminum alloy housing, an IP51 protection rating, and an operating temperature range of -30°C to +80°C. This compact unit integrates 12 independent fluid channels—comprising 3 pneumatic lines (compressed air, 0.6 MPa), 5 water lines (water, 2 MPa), and 4 hydraulic oil lines (hydraulic oil, 12 MPa)—enabling the uninterrupted transfer of various media during rotation. With a rotational speed range of 0–100 rpm, it is suitable for machinery requiring the simultaneous rotary supply of air, water, and hydraulic oil.
Key Features
Highly Integrated 12-Channel Multi-Media Design: A single unit integrating 3 air, 5 water, and 4 hydraulic oil channels—totaling 12 independent paths—replaces traditional stacked slip-ring setups and significantly simplifies the rotating assembly structure.
Compatibility with Three Pressure Ratings: Supports 0.6 MPa for air, 2 MPa for water, and 12 MPa for hydraulic oil, meeting the distinct pressure requirements of various media in a versatile, all-in-one unit.
Black Anodized Aluminum Alloy Housing: Offers corrosion resistance, excellent heat dissipation, and a professional appearance, making it suitable for diverse industrial environments.
Smooth Rotation at 0–100 rpm: Optimized for low-speed, heavy-load operation to ensure a long service life for seals and bearings, ideal for continuous-duty applications.
Simultaneous, Uninterrupted Multi-Media Transfer: Enables the concurrent transmission of compressed air, water, and hydraulic oil during rotation without cross-interference, ensuring continuous equipment operation.

Why Choose This Integrated Multi-Media Fluid Rotary Union?
An all-in-one solution for the simultaneous supply of air, water, and hydraulic oil
In heavy machinery and engineering equipment, rotating platforms often require simultaneous supply lines: air for pneumatic actuators, water for cooling systems, and hydraulic oil for cylinders. This product integrates 3 air, 5 water, and 4 hydraulic oil channels into a single unit. By replacing multiple independent rotary unions with one, it greatly simplifies piping layouts while reducing leakage risks and maintenance costs.
Precision-engineered for diverse pressure requirements
Different media have vastly different pressure demands:
Air (0.6 MPa): Suitable for standard pneumatic cylinders and grippers.
Water (2 MPa): Suitable for cooling circuits and high-pressure cleaning.
Hydraulic Oil (12 MPa): Suitable for heavy-duty drives such as hydraulic cylinders and motors.
This product features independently designed seals and flow channels for each medium, ensuring stable operation across all pressure ratings.
Durable and stylish black anodized aluminum housing
The black anodized finish enhances corrosion resistance, wear resistance, and heat dissipation while providing a professional industrial appearance, making it ideal for long-term, continuous operation.
Optimized for low-speed, heavy-duty applications with a long-life design
Optimized for speeds of 0–100 rpm under heavy loads, the unit minimizes seal and bearing wear. It offers an exceptionally long maintenance-free service life, making it particularly well-suited for equipment requiring 24/7 continuous operation.
Application Scenarios
Heavy-duty construction machinery: Simultaneous transmission of compressed air, cooling water, and hydraulic fluid for the rotating platforms of excavators, cranes, and concrete pump trucks.
Mining and metallurgical equipment: Pneumatic control, water cooling, and hydraulic drive systems for gyratory crushers, continuous casting machines, and sintering machines.
Port and marine machinery: Multi-media rotary connections for quay cranes, ship unloaders, and deck cranes.
Heavy-duty industrial automation lines: Pneumatic clamping, cooling water circuits, and hydraulic positioning systems for large rotary worktables.
Wind power and new energy equipment: Pneumatic braking, cooling, and hydraulic control for the pitch systems of wind turbines.
Frequently Asked Questions
Q1: Can all 12 fluid channels operate at full load simultaneously?
A: Yes. Each channel is independently sealed, allowing for simultaneous full-load operation. In actual application, ensure that the pressure of each medium does not exceed rated values, and consider the total thermal load and seal compatibility.
Q2: Can the water and hydraulic oil circuits be used interchangeably?
A: This is not recommended. Different media impose distinct requirements on sealing materials and flow path designs; mixing them may lead to seal failure or contamination. Please use the circuits according to their designated markings.
Q3: What is the dynamic leakage rate for the hydraulic oil circuit at 12 MPa?
A: Please refer to the product's detailed specifications for the specific leakage rate. The product utilizes specialized high-pressure rotary seals to ensure stable, long-term operation at rated pressures and speeds.
Q4: What environments is the IP51 protection rating suitable for?
A: An IP51 rating indicates effective protection against dust ingress (level 5) and resistance to vertically falling water droplets (level 1). It is suitable for most indoor industrial environments but not for scenarios involving high-pressure water jets or submersion.
Q5: The speed range is 0–100 rpm; are higher speeds supported?
A: The standard design is optimized for 0–100 rpm. Customized solutions are available for higher speeds, though seal service life and thermal balance would need to be re-evaluated.
Q6: What precautions should be taken during installation?
A: Ensure concentricity during installation to prevent excessive wear caused by runout; use flexible tubing connections to minimize radial stress on the ports; and avoid environments subject to severe vibration or impact.
