Fluid, Power and Signals into Anything That Turns
Deublin rotating unions carry water, steam, oil, air and coolant from a fixed pipe into turning machinery – rolls, drums, spindles and shafts. Norman G Clark is the exclusive Australian distributor of Deublin.

Oil & gas. Top-drive washpipes, service kits, coiled tubing unions and slip rings.
Sugar milling. Steam and water unions for heated and cooled rolls and dryers.
Timber & panel products. Hot-oil heated presses – unions for the platens and swivel joints for the moving pipework.
Commercial laundry. Steam-heated ironers and dryers.
Wind energy. Slip rings and rotary unions for turbine pitch and yaw systems.
Semiconductor. Slip rings and multi-passage unions for wafer-handling machines.
Cool a Roll with Water
Carry water into a turning roll or drum – and back out – without a leak.
Heat a Roll with Steam or Hot Oil
Bring steam or hot oil into a heated roll, and take the condensate out.
Power Clamps and Clutches
Feed air or hydraulic oil to chucks, clamps, clutches and brakes as they turn.
Several Supplies, One Shaft
Keep oil, air, coolant and vacuum apart inside one union.
Coolant Through the Spindle
Feed coolant, oil mist or air through a machine tool spindle at high speed.
Let Pipework Move
Swivel joints let pipes turn and tilt with presses, arms and platens – safer than hose.
Keep the Rig Turning
Long-life washpipes, service kits and unions for drilling rigs.
Power and Signals Too
Slip rings pass electricity and data into turning machines – alone or with fluids.

How they seal
Four Ways a Rotating Union Seals
Pressure Joints
Sealed by the pressure of the fluid, with a strong spring for start-up. Simple, but they take more effort to turn and suit only low pressures (under 17 bar).
Soft Seals
Polymer seals: compact, and good for slow or stop-start turning – but they wear and warm up faster.
Hydrostatic Seals
The turning part floats on a thin film of fluid, so nothing touches. Long life at high pressure, but limited to a few thousand rpm.
Mechanical Seals
Precisely flat, balanced seal faces: low wear, low heat, and they work above 140 bar and 40,000 rpm.
