There is nothing available as a backup. (The pump is still in use; I’m not sure what the risks might be?) What should be done when encountering such special media?
I suspect the original poster might have asked the wrong question. You said there was a problem with the backup pump; its inlet and outlet were closed, pressure was released through a pressure relief line, and the nitrogen line was used for purging. All that’s needed is to disassemble the pump for repair – after all, it can’t just be left unrepaired, right?
Internal leakage in the pump occurs due to severe wear of the internal ring in the pump, which leads to such leakage. The direct consequence is a decrease in the discharge volume at the pump’s outlet; in severe cases, the pump is unable to meet the minimum discharge requirements specified by the process, resulting in reduced efficiency. It’s fine to run it for a short time, but it must be repaired in severe cases. It’s unlikely that both pumps will experience internal leakage at the same time; if it does happen, it’s due to poor equipment management, and the fault lies with those responsible.
Reply to 3# Gobi Divine Fox: Haha, yes. They rarely carry out maintenance on the other backup unit. It was only when I replaced the pump that I realized both units had problems. But they were necessary to use, so I chose one to continue using while leaving the other for repair (I had no choice but to do this). Thank you for your advice!
