What's Wrong With The Self-priming Pump Making A Current Sound But Not Turning

Nov 14, 2024

Recently, some users will ask why the self-priming pump has a current sound but is not turning. The sound of electric current coming from a self-priming pump and not rotating is caused by various reasons. For example, it may be caused by foreign objects inside the machine, or it could be a problem with the motor. The motor is not rotating due to the sound of current, or the motor bearings are rusted and stuck due to lack of oil.
Self priming pumps have a certain pressure control system, which usually automatically stops when the system pressure is sufficient. If it is insufficient, it will continue to work until the increased pressure reaches the preset pressure. It is normal for the self-priming pump to not make a sound. The frequency of its sound is a problem with the pressure control system of the self-priming pump. You can contact the staff for maintenance and inspection. The self-priming pump is plugged into the power supply, and only the current buzzes but does not work. To solve this problem, we need to study it carefully and identify the problem, so that we can prescribe the right medicine, otherwise we won't be able to find the problem. Unable to handle and resolve properly.

(1) If the motor makes a buzzing sound, it will not rotate, and the motor blades can also rotate. If there is, it needs to be replaced with a new one.
(2) The motor bearings are stuck due to lack of oil, rusting, or pump rusting. In this case, it cannot be used anymore and needs to be repaired immediately by cutting off the power.
(3) It is very likely that there is a blockage, and this possibility is high. The solution is to block the self-priming pump, only by unblocking can the problem be solved.
(4) There should be an issue with the motor of the self-priming pump. The solution is to promptly send the motor of the self-priming pump to the maintenance department for cleaning. In addition to the above situations, there are other reasons such as insufficient pressure, cavitation of the self-priming pump, and damage to the self-priming pump.
