What is the type of sealing water for the pump? Some use self-media flushing, while others use external water – what determines this?
The main factor is whether the medium itself is clean; if there are particles present, they can damage the sealing surface.
Is there a standard or requirement for that? For example, there is a limit on the level of particulate matter that is permissible
I checked the information I have, and there’s no mention of it
You can take the time to check out API682.
Well, let’s take a look at API mechanical seals
You can search on Baidu for mechanical seal flushing solutions
Original poster, A&P&I standards cannot be uploaded to the forum. However, there are quite a few training materials related to 682, so you can look for them. If they’re not available on the forum, I can help you find them through other channels
