|---|---|---|
| Size Range | Shaft diameters from 10 mm to 300 mm | |
| Shaft Speed | Up to 5000 rpm | |
| Leakage Rate | <10 mg/m³ for emissions control | |
| Pressure Range | Up to 100 bar | |
| Temperature Range | -50°C to 400°C |

Mechanical seals use precision faces for a leak-tight seal with minimal maintenance, ideal for high-pressure or hazardous fluids. Packing seals use compressed fibrous material, requiring adjustment and allowing slight leakage for lubrication, often used in less critical applications.
Replacement intervals depend on operating conditions: mechanical seals typically last 1-5 years, while packing seals may need adjustment every few months and replacement every 6-24 months, based on wear, fluid abrasiveness, and maintenance schedules.
