Differences between mechanical seals for hot and cold water pumps
Thread Content
What is the difference between the two? If hot water at 120 degrees is passed through a cold water pump (at normal temperature), will it damage the seal or other components?
If the medium temperature exceeds 80 degrees, the flushing plan should consider adding cooling measures! Otherwise, it is very detrimental to the mechanical seal!
The mechanical seal cannot achieve a normal service life. The selection of materials for temperature-friction pairs varies depending on the medium
Is it still water at 120°C? Has it boiled?
Under high pressure, it is no longer gaseous.
Mm-hmm, yes, I hadn’t considered that. Is Manager Qu from Yantai Shengquan still working at your company?
It’s also necessary to check whether the accompanying rubber ring can withstand such temperatures (frictional heat is generated in addition to the temperature of the medium)
With mechanical seal cooling water, in extreme cases, no water film can be formed at the ends, resulting in direct dry grinding and the immediate failure of the mechanical seal
What is the maximum temperature that a mechanical seal can withstand? What is the maximum temperature that a packing seal can withstand?
