Pump Cavitation Detection

The Problem

“Detect pump cavitation early from industrial sensor data to prevent damage, downtime, and energy loss”

Organizations face these key challenges:

1

Cavitation signatures vary with load, suction conditions, fluid temperature, and pump design

2

Fixed thresholds generate false positives during normal process transients

3

Early-stage cavitation is difficult to detect from single-signal monitoring

4

Operators lack labeled examples distinguishing cavitation from other anomalies

5

Sensor quality, missing data, and inconsistent historian tags reduce model reliability

6

Maintenance teams often discover cavitation only after performance loss or component damage

7

Remote or distributed assets make manual inspection expensive and slow

8

Operational context is not consistently incorporated into diagnostics and alerting

Impact When Solved

Reduce unplanned pump downtime by detecting cavitation before severe damage occursLower maintenance cost through earlier intervention and fewer catastrophic failuresImprove pump efficiency and reduce energy waste from degraded hydraulic performanceIncrease mean time between failures for seals, bearings, and impellersReduce false alarms by separating cavitation from other process and mechanical anomaliesSupport maintenance scheduling with risk scores, severity trends, and early warningsStandardize diagnostics across fleets, sites, and operating regimes

The Shift

Before AI~85% Manual

Human Does

  • •Review periodic vibration, acoustic, pressure, and flow readings for signs of pump distress
  • •Investigate alarms and compare operating conditions to pump curves and NPSH requirements
  • •Inspect suction path, valves, strainers, seals, and bearings to identify likely cavitation causes
  • •Decide on process adjustments, maintenance actions, or pump shutdown based on expert judgment

Automation

  • •Trigger basic threshold alarms from monitored vibration, pressure, flow, or temperature signals
  • •Log operating and alarm history for later review
  • •Display current readings and trends for operator interpretation
With AI~75% Automated

Human Does

  • •Approve operating changes to restore safe pump conditions when cavitation risk is elevated
  • •Prioritize maintenance or inspection actions based on AI risk, production impact, and equipment criticality
  • •Handle exceptions when alerts conflict with field observations or process constraints

AI Handles

  • •Continuously monitor multi-sensor pump behavior to detect early and intermittent cavitation
  • •Distinguish likely cavitation from similar issues such as recirculation, entrained gas, or bearing problems
  • •Generate cavitation risk scores, health trends, and early warnings for affected pump trains
  • •Recommend likely root-cause areas and suggested operating responses based on correlated process conditions

Operating Intelligence

How it works

AI runs the first three steps autonomously.

Humans own every decision.

The system gets smarter each cycle.
