Parameter | Value/Description | Unit/Note | |
---|---|---|---|
Model | QT-PG | Pressurized gas mechanical seal for process applications | |
Seal Type | Single/Double (Gas-Lubricated Non-Contact Design) | Non-contacting for zero liquid leakage, suitable for gas-only systems | |
Face Materials | - Rotating: Tungsten Carbide (WC) with spiral grooves - Stationary: Silicon Carbide (SiC) |
Grooved faces generate hydrodynamic lift with gas media | |
Housing Material | Stainless Steel 316L / Hastelloy C-276 | Corrosion-resistant for acidic or high-temperature gases | |
Pressure Range | 0 - 3.0 (Single Seal) 0 - 6.0 (Double Seal) |
MPa | Double seal for higher pressure gas containment |
Shaft Diameter Range | 40 mm - 120 mm | Fits industrial compressor/turbine shafts | |
Maximum Rotational Speed | 12,000 | RPM | High-speed compatibility for gas turbines |
Temperature Range | -80°C ~ 200°C | Suitable for refrigerated gases and hot process streams | |
Leakage Rate | ≤100 standard cm³/h (Single Seal) ≤20 standard cm³/h (Double Seal) |
Meets EPA/ISO emission standards for volatile gases | |
Lift-off Pressure | 0.1 | MPa | Minimum gas pressure to establish non-contact film |
Standards Compliance | API 682 (Type B), ISO 14694, ASME BPVC Section VIII | Certified for pressure vessels and high-integrity systems | |
Key Features | - Low friction (gas film lubrication) - Long service life (5+ years) - No external lubrication required |
Reduces energy consumption and maintenance compared to oil-lubricated seals |
