Discussion on the reasons for shaft breakage in magnetic pump

After running for a month, the magnetic pump produced abnormal noises; upon disassembly, it was found that the threads on the pump shaft were broken and the shaft sleeve was damaged. Please analyze and determine the reasons for the pump damage.
Operates at low flow, vibrates and then breaks.
Is it due to low flow for a long period of time, or periods of vacuum, with high temperatures causing an excessive pressure difference? It is also possible that the shaft alignment is too small during assembly. It’s also possible that fatigue or defects occurred during forging.
What about the fracture shape? Perform a metallographic analysis; also, what is the size of this gap?
The idea of asking others for help and also asking them to charge money – what do you think of that?

I’m very sorry; I ordered the wrong one, and it can’t be changed after it’s been sent.
I just found the way to edit it and have made the changes. Please forgive me too
The flow rate was stable, but the current fluctuated suddenly; afterwards, abnormal noises were heard from the pump on site. The pump was stopped only after maintenance personnel inspected it. The process handling is delayed
Your medium is severely coked, right? Has it blocked the flow channels of the flushing sliding components? Only then did a series of damages occur.
