Among the components of the pump, mechanical seals are important components, and mechanical seals are also wearing parts. If the mechanical seal is damaged, the pump body will leak. If a direct-coupled pump is used, the medium in the pump body will seep into the motor and damage the motor. Therefore, the quality of the mechanical seal is critical.
To improve the efficiency of the pump and extend the service life of the pump shaft seal, the normal use of the pump, the maintenance is the key. Many mechanical seal users often ignore the problem: let the pump idling in the absence of medium. The damage of the seal is very large, not only greatly increasing the wear of the mechanical seal itself, but also causing more serious damage to the seal due to the high temperature generated by the high speed friction. In fact, many users complain that 'a certain mechanical seal does not take long to damage' is caused by this reason. Therefore, we must pay attention to this detail in the use of the pump - the pump can not idle!
