New member seeking help with pump port ring issues
Thread Content
Recently, while watching a fitter disassemble pumps, I noticed that some of our vertical pumps didn’t have ring gaskets. When I checked other pumps that had been disassembled, I found that many of them also lacked ring gaskets. Is the ring gasket really that important? Since it helps prevent leaks, improves efficiency, and reduces operating costs, why not install ring gaskets on all pumps?
The mouth ring is important for improving efficiency, but less important in terms of resistance to damage; if there are impurities present, the mouth ring is more likely to get damaged
Whether a mouth ring is needed is not absolute; the choice should be made based on the actual operating conditions of the pump.】
Is it that the pump you’re using doesn’t require a mouth ring in the first place?
Mine is a vertical liquid sulfur pump; I can’t explain it clearly
I’m not sure about this; you can consult the manufacturer of this pump. They should be able to resolve your doubts.
This might be because we use liquid sulfur, which contains things like carbon
Neither open impellers nor semi-open impellers have mouth rings.
All impellers I have come into contact with are closed impellers
It must also have something to do with the medium; one of the gray water pumps in our factory doesn’t have a sealing ring installed to prevent damage
An orifice ring can reduce the gap and improve pumping efficiency. However, the mouth ring wears out over time and is a consumable item; too small a gap can cause the impeller to make contact and experience dry friction
