Eight factors that cause damage to the self-priming centrifugal pump :
1. Evacuation, cavitation or rolling for a long time, resulting in seal damage;
2. The actual output of the pump is too small, a large number of media pumps circulate, heat accumulates, causing gasification of the medium, resulting in seal failure;
3. The return flow is too large, causing the sediment at the bottom of the suction side container to rise and damage the seal;
4. For a longer period of time, there is no manual turning when restarting, and the friction pair tears the sealing surface due to adhesion;
5. Increased corrosive dynamic torque sensor, polymerizable and gelatinous substances in the medium;
6. The ambient temperature changes drastically;
7. Frequent changes or adjustments in working conditions;
8. Sudden power outage or downtime. The centrifugal pump suddenly leaks during normal operation. If it cannot be found in time, it will often cause a big accident or loss. It must be taken seriously and effective measures taken.
