A centrifugal pump has experienced three mechanical seal failures within six months.
How would we determine whether the root cause is hydraulic, mechanical, operational, or installation related?

Three mechanical seal failures within six months should be treated as a reliability problem, not simply a seal problem. Replacing the seal repeatedly without identifying the underlying cause almost always leads to further failures. A structured Root Cause Analysis should separate the causes into hydraulic, mechanical, operational, and installation categories.
