Key Features

Reliable Mechanical Seal Technology

Our rotary unions are equipped with high-performance mechanical seals that maintain a consistent, leak-free seal between stationary and rotating components. This design is ideal for handling high-pressure and high-speed fluid transfer applications, ensuring extended service life with minimal maintenance.

Wide Media Compatibility

Compatible with a broad range of media, including water, steam, oil, coolant, hydraulic fluid, and air. The mechanical seal materials (such as carbon vs. ceramic, silicon carbide, or tungsten carbide) are selected based on media type and working temperature, offering excellent chemical resistance.

High Pressure and Temperature Resistance

Designed to operate under pressures up to 150 bar (2175 psi) and temperatures exceeding 200°C (392°F), making them ideal for demanding industrial environments such as steel, plastics, and paper manufacturing.

Versatile Design Options

Available in single-flow and dual-flow passages, with customizable port sizes (NPT, BSP, metric threads), housing materials (stainless steel, brass, aluminum), and mounting types (flange, threaded, foot-mount). This modular approach ensures easy integration into both OEM and retrofit systems.

Long Service Life and Low Maintenance

Thanks to precision-engineered seal faces and balanced seal loading, our mechanical seals and rotary unions reduce wear and friction, lowering maintenance requirements and operating costs over time.

Corrosion-Resistant Construction

Housing options in marine-grade stainless steel, anodized aluminum, or nickel-plated brass provide excellent protection in corrosive or wet environments, ideal for food processing, chemical plants, or offshore applications.

High-Speed Operation

Engineered with precision bearings and dynamic balancing for smooth performance at rotational speeds of up to 10,000 RPM, depending on size and media. Ideal for high-speed CNC machining and spindle cooling systems.
