What happens if the outlet remains closed after the centrifugal pump starts?
It can’t turn anymore, why don’t you give it a try?
The temperature inside the pump should rise quite a bit
After the centrifugal pump is started, if the outlet remains closed, the temperature will rise; however, it has not been tested with the pump running continuously for a long time.
It’s likely to burn out the motor; P
That’s complete nonsense; how could the motor get burned?
Seal failure leading to leakage, excessive pump shaft torque causing fracture
As the temperature rises, cavitation occurs. This ultimately leads to pump body vibration, seal leakage, and bearing damage
It’s likely the mechanical seal that failed first; the pump body temperature is very high
For magnetic drive pumps and shielded pumps, it is not allowed to close the outlet, as this can lead to high temperatures that cause leakage; for mechanical seal and packing pumps, the impact should be minimal.
