The cooling effect of the self-flushing water cooler for mechanical seals is very poor; what consequences can this have?

It’s been a long time, but the pump hasn’t had any major problems
Using a clean, non-crystalline medium poses no problem; if the medium is dirty and contains crystals, it would have leaked long ago
The mechanical seal can wear out severely, leading to leaks and splashing
As long as it does not reach the vaporization temperature of the flushing medium and the temperature that the mechanical seal ring can withstand. It’s no big deal!
1. The main reason is that high temperatures cause the O-rings to age too rapidly； 2. Secondly, high temperatures cause the O-rings to soften, reducing their sealing performance and potentially leading to premature leakage ； 3. Due to high temperatures, the lubricating film cannot form properly on the sealing surface, which accelerates wear of the sealing end face. If there’s a chance, clean the cooler as soon as possible. A set of mechanical seals with flushing fluid can cost several thousand dollars, while cleaning the cooler itself doesn’t cost much; one shouldn’t sacrifice something important for a small gain.
