Vaporized pump seal
Thread Content
Does the gasified filter press feed pump use a packing seal or a mechanical seal?
It is more suitable to seal with packing. 1. The technical requirements for this pump are not high. Its working pressure and temperature are very low, and ordinary seals can fully meet the requirements. ； 2. The leakage requirements of this pump are not too high, so there is no need to use a mechanical seal. ； 3. This pump has a large amount of impurities and a high solid content. The use of mechanical seals will easily cause seal damage, and the maintenance cost is high and complicated. Although the same is true for the packing, the replacement cost is low and the maintenance is simple. ； 4. Considering the process requirements and investment, there is no need to spend more money.
Use packing to seal, shaft seal water is very important
The opinions are relatively unified, and I support what everyone above said, use packing to seal, but there must be shaft seal flushing water.
