Introduction
Pump sealing is essential to prevent leakage and maintain efficiency. Two common sealing methods are mechanical seals and packing.
Mechanical Seal
A mechanical seal uses rotating and stationary faces to prevent leakage.
Features
- Low leakage
- Suitable for high pressure
- Requires proper installation
Packing (Gland Packing)
Packing uses compressible material around the shaft.
Features
- Simple structure
- Lower cost
- Requires regular adjustment
Comparison
- Leakage: Mechanical seal is lower
- Maintenance: Packing requires more
- Cost: Packing is cheaper
Selection Criteria
- Fluid type
- Pressure
- Maintenance requirements
Conclusion
Choosing the right sealing method improves pump reliability and reduces downtime.
