The DEUBLIN 1115 series is a single-channel, balanced mechanical seal rotary union designed for high-speed dry gas or lightly lubricated gas applications. It features a compact, self-supported design with an anodized aluminum housing, stainless steel rotor, and permanently lubricated bearings – ideal for mounting at the end of high-speed spindles.
Parameter | Typical Value (Gas Media) | Notes |
|---|---|---|
Max. Speed | Up to 15,000 rpm | Model dependent |
Max. Pressure | 10 bar (≈145 psi) | For gas media only |
Max. Temperature | 121°C (≈250°F) | |
Media | Dry air, lubricated gas, hydraulic oil, vacuum | Some models support coolant/MQL |
Design Features | Balanced silicon carbide seal, full flow design, radial housing connection, lifetime lubricated bearings | |
Materials | Housing: anodized aluminum; Rotor: stainless steel |
Special models (e.g., 1115-009-386) also support water-based coolant and MQL at pressures up to 10 bar or higher – always verify the exact model data sheet.
