If the inlet is blocked, will the pump jump?

If the inlet is blocked due to material, will the pump jump? Is this what you mean by idling? The water quality was very good at first because the water was being changed all the time. But now it is not allowed to drain out, the water quality is very poor, around ph12-13, and the pump has been jumping frequently in the past few times. The outlet pressure of the main pipe is not as high as before. Even if the outlet is opened very wide, the pressure cannot be raised. It is possible that the import is blocked. That's why I wanted to ask if the inlet is blocked, will the pump jump?
If the inlet is blocked, the pump will be empty.
If the pump inlet is blocked, the feed volume will be reduced, and the liquid in the pump will be reduced. Long-term operation will cause the pump body to heat up, the liquid in the pump will vaporize, produce air traps, the current will be unstable, and then the pump will stop.
If the pump inlet is blocked, it will be evacuated. Of course, the pressure will drop. If it is blocked, there will be no pressure at all. The friction heat between the bearing and the sleeve cannot be taken away during long-term operation, and the bearing will easily burn out.
The inlet is blocked, the pump is evacuated, and the axial force changes, which accelerates pump wear.
The inlet is blocked and there is no fluid in the pump casing, causing the pump to idling and heating, and the gasification outlet pressure cannot rise.
There is no flow at the inlet and the pump is empty.
The outlet pressure is not as high as before, the pressure fluctuates greatly, and the pump vibrates loudly and makes loud sounds. If the pressure rises when the pump outlet valve is closed, it can basically be concluded that the inlet is blocked.
If the inlet is blocked, it is equivalent to idling the pump and the motor will not burn out.
