What will happen if the pump’s bearings are damaged?
Thread Content
I would like to ask everyone, what problems can occur if the bearings of a pump are damaged? (Not a motor bearing)
That’s serious – in mild cases the motor will burn out, and in severe cases the entire pump will become unusable
If the pump’s bearings fail, the consequences are: 1. The motor overloads and shuts down (shaft seizure)； 2. If the motor does not trip due to overload, it will eventually lead to wear of the pump shaft, until it becomes unusable ； 3. If wear increases the vibration of the pump, it will lead to wear of the pump’s impeller and mouth ring, as well as damage to the mechanical seal, until the entire pump becomes unusable ； Last edited by Qingzhe on 2007-11-29 18:08]
In our production, we encountered a situation where the bearing of the ethanol pump was damaged, which led to the failure of the mechanical seal and ethanol leakage. The increased temperature resulting from dry friction due to the damaged bearing ignited the leaked ethanol, causing a fire.
This is exactly the case with bench pumps, and the following problems occur: 1. Damage to the pump seal, either the stationary ring or the rotating ring; 2. Damage to the pump seal shaft sleeve; 3. The pump bearings seize, preventing the pump from starting

Motor burnout, damaged impeller, worn or burned pump shaft, etc
