1. Sealing Structure
• Mechanical seal: Face contact static & dynamic seal, precision end-face friction pair
• Gland packing: Soft packing compression seal, contact shaft circumferentially
2. Leakage Performance
• Mechanical seal: Extremely low leakage, nearly zero leakage
• Gland packing: Obvious allowable leakage, cannot achieve zero leakage
3. Service Life
• Mechanical seal: Long service life, low replacement frequency
• Gland packing: Short service life, easy wear, frequent replacement
4. Friction & Power Consumption
• Mechanical seal: Small friction resistance, low power loss
• Gland packing: Large friction resistance, high energy consumption
5. Maintenance
• Mechanical seal: Maintenance-free in service, simple replacement
• Gland packing: Needs regular tightening and frequent maintenance
6. Application
• Mechanical seal: Pumps, reactors, high speed / high pressure / corrosive working conditions
• Gland packing: Low pressure, low speed, simple ordinary equipment
