Air separation high-pressure oxygen pump

The air separation high-pressure oxygen pump (imported pump: French Cryostar CRYOSTΛR S.Λ.S) was operating normally; suddenly, within about 20 seconds, the temperature of the motor bearing rose from 45°C to 120°C, which triggered an automatic shutdown. During this process, neither the current nor the flow rate of the pump changed. Could anyone help analyze this situation?

Perform a disassembly inspection; check it together with the pre-pump filter to find out. We also need to check for any phase loss or overcurrent issues related to electricity.

Has it been running steadily, or did this occur after maintenance?
