Can vacuuming caused by atmospheric and reduced-pressure pumps lead to a fire?

If a pressure device under normal pressure experiences pump evacuation (with gasoline or diesel as the medium), and if this is not detected in time, could pump evacuation lead to a leak of the medium and thereby cause a fire?

It shouldn’t be the case, because although the temperature will rise, the environment is relatively sealed and lacks oxygen and other elements that aid combustion
Anything is possible. Pump evacuation can cause heating, seal failure, and leakage.
That’s possible. Diesel has a high extraction temperature and a low auto-ignition point; pump evacuation can cause heating, failure of the mechanical seal, and leaks, which can then lead to ignition
It is entirely possible that without a flushing fluid, the mechanical seal generates a lot of heat, which can cause the remaining oil to catch fire
It’s possible with heavy diesel; the pump drawing air can cause the mechanical seal to fail and leak, leading to spontaneous ignition. Other light oils will also leak; the possibility of spontaneous combustion is low, but who knows where they might flow. . .
The pump will not catch fire when it is under vacuum, but if the seal’s elasticity fails at that time, high-temperature oil will leak out and this can cause a fire.
Without a medium, dry operation will cause smoking, and eventually the mechanical seal will leak heavily; with static electricity present, it can lead to a fire.
Pumping the pump empty for an extended period will definitely lead to seal leakage, which may cause a fire. But when the pump is pumped empty, there’s no output or supply left – how could one not notice that? Taking timely action should be sufficient to avoid such problems
The mechanical seal area of pump machines can be monitored using infrared thermal imaging; issues such as a blocked flushing system, poor circulation in the white oil system, or inadequate cooling performance of the flushing and cooling systems can be detected in advance, allowing for timely prevention
Is infrared thermography an online monitoring method?
