Mechanical seals and packing seals are two common shaft sealing methods that each have advantages in terms of leakage control, maintenance requirements, cost, and application suitability. Here are some of the main advantages of mechanical seal wholesale over packing seals:
- Mechanical seal: Provides better leakage control and can achieve almost zero leakage. This is because mechanical seals including mechanical seal for agitator prevent fluid leakage through a pair of precision-fitted sealing surfaces (usually one fixed and one rotating).
- Packing Seals: Although lower in cost, their design allows for trace leakage as part of normal operation to cool and lubricate the packing. This leakage may increase over time.
- Mechanical seals: While initial installation may be more complex and costly, maintenance costs and requirements are typically lower in the long term due to their lower leak rates and longer maintenance intervals.
- Packing seal: requires regular adjustment and replacement to control leakage, maintenance is relatively frequent and costly.
- Mechanical seal: Initial cost is higher, but long-term cost-effectiveness may be better due to its longer service life and lower maintenance requirements.
- Packing seals: Initial cost is lower, but long-term operating costs may increase due to the need for frequent maintenance and replacement.
- Mechanical seal: Suitable for a wide range of applications, especially when dealing with hazardous, volatile or valuable media, where its excellent leakage control performance is particularly important.
- Packing seals: Although suitable for many standard applications, they may not be the best choice where extremely tight leakage control is required.
Overall, while mechanical seals from Zhaoqiang have higher initial cost and installation complexity, they have clear advantages over packing seals in terms of leakage control, maintenance requirements and long-term cost-effectiveness. And packing seals still have their place in cost-sensitive applications with less stringent leakage requirements.
