Pump Condition Monitoring

What this topic covers

Hydraulic performance, vibration, temperature, seals and process conditions around pumps.

Core ideas

Pump condition depends on both the machine and the hydraulic system it serves.

Flow restriction, cavitation, recirculation, misalignment and wear can create overlapping symptoms.

Reliable diagnosis combines process variables with mechanical condition data.

Program tradeoffs

Load, speed and operating state can change signals even when machine condition is unchanged.

What good evidence looks like

Diagnosis should combine vibration, temperature, lubrication, process and maintenance history where appropriate.

Lifecycle perspective

Monitoring should produce actionable work or engineering review rather than accumulating alarms without response.
