A mechanical seal or gland packing system that prevents fluid leakage around rotating shafts in industrial agitators.
A precision-engineered sealing component designed to maintain a pressure-tight barrier between the rotating shaft of an agitator and its stationary housing, preventing process fluid leakage, contamination, and environmental release while accommodating shaft movement and wear.

这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
Mechanical seals use precision lapped faces for near-zero leakage with minimal maintenance, while gland packing uses compressed fibrous material requiring periodic adjustment and allowing controlled leakage for lubrication.
Mechanical seals typically last 2-5 years with proper operation; gland packing requires adjustment every 3-6 months and replacement every 1-2 years depending on operating conditions and media.
