How the Deublin 1102 Series Rotary Union Works

The 1102 series rotary union uses a single-passage (monoflow) design, allowing fluid to transfer smoothly between stationary piping and rotating equipment.

Its precision bearings and mechanical seals maintain alignment and prevent leakage during continuous rotation, ensuring:

• Stable pressure
• Smooth rotation
• Minimal maintenance

👉 This makes it ideal for compact hydraulic and pneumatic systems.
