Predictive Monitoring of Seal-less Pumps

In the past, spared critical machinery was automatically designed into plant expansions. With today’s advancing technologies, it is becoming more economical to install unspared critical machinery.  To do so, a reliable method of condition monitoring must be implemented that is capable of accurately and consistently detecting conditions that lead to machinery failure.

Variances in process conditions can cause premature machine failure. In many cases, these failures are sudden and catastrophic. Conventional methods of periodic monitoring are sometimes not adequate to catch the sudden failure, and continuous monitoring protection systems are often difficult to justify due to their cost. A method must be used that is both economically implemented and that provides advanced signal processing and continuous monitoring.  This application note goes into detail about the above theory and provides supporting test results.
