Pump & Motor Vibration Analysis Inspection Checklist [FREE PDF]

Pump and motor vibration analysis is a critical predictive maintenance discipline governed by ISO 55000 Asset Management standards and OSHA 1910.147 lockout/tagout requirements during equipment access. Regular vibration monitoring enables early detection of bearing degradation, rotor imbalance, and shaft misalignment before catastrophic failure occurs. This checklist guides Reliability Engineers and Maintenance Technicians through a systematic vibration assessment protocol aligned with SMRP Best

  • Industry: Manufacturing
  • Frequency: Monthly
  • Estimated Time: 45-60 minutes
  • Role: Reliability Engineer
  • Total Items: 37
  • Compliance: OSHA 29 CFR 1910.147 - Control of Hazardous Energy (LOTO), OSHA 29 CFR 1910.212 - General Machine Guarding, NFPA 70E-2021 Article 130 - Electrical Safety Work Practices, ISO 55000:2014 - Asset Management Systems, SMRP Best Practice 2.2.2 - Vibration Analysis

Pre-Inspection Safety & LOTO Verification

Verify all lockout/tagout and PPE requirements are met before approaching rotating equipment.

  • Has a written LOTO procedure been reviewed for this equipment prior to any physical contact?
  • Is appropriate PPE (safety glasses, hearing protection, gloves) donned before beginning inspection?
  • Have all machine guards been confirmed intact and in place before initiating vibration readings?
  • Is the vibration analyzer calibrated with a valid calibration certificate current within 12 months?
  • Has the work permit or maintenance notification been issued and approved for this inspection task?

Visual Equipment Condition Assessment

Conduct a thorough visual inspection of pump, motor, and coupling before taking vibration measurements.

  • Is the motor housing free from visible cracks, corrosion, or physical damage?
  • Are all mounting bolts and baseplate anchor bolts visually intact and showing no signs of loosening?
  • Is the flexible coupling guard present, undamaged, and properly secured?
  • Are there any visible oil or fluid leaks from pump seals, bearing housings, or drain points?
  • Are vibration measurement pads or permanent sensor mounts clean and free from paint or debris?
  • Please document any observed abnormalities noted during visual inspection.

Motor Vibration Measurements

Record vibration velocity and acceleration readings at defined motor measurement points.

  • Is the overall vibration velocity at the motor drive-end bearing within acceptable limits (≤ 0.1 in/s RMS)?
  • What is the measured vibration velocity (in/s RMS) at the motor drive-end bearing in the horizontal direction?
  • What is the measured vibration velocity (in/s RMS) at the motor non-drive-end bearing in the vertical direction?
  • Does the FFT spectrum at the motor drive-end show elevated 1X running speed amplitude indicating rotor imbalance?
  • Are high-frequency bearing defect frequencies (BPFI, BPFO, BSF) elevated beyond 10 g peak in the HFD band?

Pump Vibration Measurements

Record vibration readings at pump bearing housings and assess pump-specific fault conditions.

  • Is the overall vibration velocity at the pump drive-end bearing within acceptable limits?
  • What is the measured vibration velocity (in/s RMS) at the pump outboard bearing in the axial direction?
  • Is vane pass frequency (number of impeller vanes × RPM) elevated, indicating hydraulic instability or cavitation?
  • Is the pump operating within its specified flow range (between 70%–120% of best efficiency point)?
  • Are vibration readings trending upward more than 25% compared to the previous monthly baseline measurement?

Shaft Alignment & Balance Assessment

Evaluate coupling alignment condition and rotor balance status using vibration signature analysis.

  • Does the vibration spectrum show elevated 2X running speed amplitude indicating angular or parallel misalignment?
  • When was the last precision laser alignment performed on this pump-motor set?
  • Is the axial vibration level at the motor less than 50% of the highest radial reading, indicating acceptable alignment?
  • Has a soft foot condition been checked and corrected at the motor or pump base within the last 6 months?
  • Is field balancing required based on current 1X vibration amplitude and phase analysis?

Bearing Temperature & Lubrication Check

Assess bearing operating temperatures and lubrication condition to complement vibration data.

  • What is the measured bearing temperature at the motor drive-end bearing housing?
  • What is the measured bearing temperature at the pump outboard bearing housing?
  • Is the bearing housing temperature stable (less than 10°F rise within 30 minutes of startup)?
  • Is the grease or oil level in the bearing housing at the correct level per OEM specifications?
  • Is the lubricant free from contamination, discoloration, or evidence of water ingress?

Findings, Recommendations & Work Orders

Document overall assessment results, corrective action recommendations, and work order generation.

  • What is the overall vibration health condition of this pump-motor set based on current readings?
  • Has a corrective maintenance work order been raised for any findings identified during this inspection?
  • What is the recommended timeframe for the next vibration inspection based on current condition?
  • Have all vibration data readings been uploaded to the computerized maintenance management system (CMMS)?
  • Please provide a detailed summary of all findings, anomalies observed, and recommended corrective actions.
  • Was this inspection completed without any safety incidents or near-misses?
