The main causes of pump cavitation are large pump inlet pipe resistance, more gas phase of conveying medium, insufficient filling pump, insufficient pump inlet energy head and so on. Cavitation is the most harmful to the pump. When cavitation occurs, the pump vibrates violently and the balance is severely damaged, which will cause damage to the pump bearing, rotor or impeller. This is a common cause of magnetic pump failure.

This is a common cause of magnetic pump failure.

Dry friction between the rotor main shaft and the stable bearing, and burn the bearing. The magnetic pump is provided by the transmission medium to the sliding bearing lubrication and cooling, in the absence of the inlet valve or outlet valve, the sliding bearing due to no transmission medium lubrication and cooling caused by high temperature and thus damage.

The magnetic coupling of the magnetic pump is cooled by the medium transported by the pump. If there are hard particles in the medium, it is easy to cause the isolation sleeve to be scratched or scratched. Sometimes, if the maintenance method is improper, it may also cause damage to the isolation sleeve.

If it is also accompanied by a decrease in flow, it is necessary to consider that the internal components are abnormal. It should be clear that some unknown manufacturers may have poor production quality when making magnetic pumps, such as asymmetry of the unit axis, swing exceeding allowable values, and poor mechanical strength and rigidity of parts.
