These condition monitoring methods estimate increased power consumption due to wear
Pumps are arguably the most common machine in the
power and process industries, yet relatively little
information is available on applying predictive maintenance
(PdM)/condition monitoring. When deterioration in performance
of a centrifugal pump causes a drop in plant production,
overhaul is readily justified, as its cost is usually small
in proportion. When the effect of deterioration is only to
increase power consumption, the time to overhaul for minimum
cost can be calculated from test results. Some basic
condition monitoring tests for pumps are described. These
condition monitoring methods can be used to estimate the
