Disassembly of a multi-stage pump, internal erosion condition
Thread Content
The erosion condition of this pump is complex
Just replace the impeller. Usually, the sewage pumps in steel mills behave in this way – due to iron powder, limestone, and other substances that cause erosion and corrosion. For reference.
What type of medium does this pump handle? I also have a pump used for transporting deoxygenated water; the medium in that case is very clean, but corrosion is still severe. I would appreciate it if you could help analyze the reasons for this
Has it reached this extent? It still works?
We have a pump here that has been in use for almost 10 years; now it seems to have insufficient flow rate, although the pressure at the pump’s outlet is still adequate. Even when taken apart, nothing seems to be wrong.
It’s just that there’s often gas present; not much of it, and it forms after the bubbles burst. I understand it to be that way
