Pump diagnostics
Pump vibration diagnostics
Investigate vibration across the motor, coupling and pump, with operating conditions recorded to distinguish mechanical concerns from process-related change.
Asset-specific vibration analysis
Separate the mechanical fault from the process effect
Pump vibration can change because of the rotating assembly, the support structure or the hydraulic operating point. EchoShift combines vibration measurements with speed, load and process context so a strong signal is not automatically blamed on the nearest bearing.
A focused diagnostic can help decide whether maintenance should concentrate on bearings, alignment, coupling, mounting, rotating balance, process condition or further hydraulic investigation.
Maintenance triggers
When to book pump vibration analysis
Pump work usually starts with a symptom: rising vibration, bearing noise, a coupling or alignment concern, or behaviour that changes with flow or load. The visit follows that symptom across the motor-pump train.
Bearings, seals or couplings are failing more often than expected
A pump was recently aligned, rebuilt or returned to service
The vibration changes strongly with flow, pressure or operating point
What we investigate
Vibration evidence tied to the machine
Motor and pump vibration are compared across bearing positions with speed and process condition recorded, helping separate rotational mechanics from hydraulic or structural effects.
Bearing condition
Measure bearing housings for changes in overall, spectral and higher-frequency vibration.
Alignment and coupling
Axial, radial and harmonic behaviour can show when coupling or alignment deserves attention.
Imbalance and rotating forces
Running-speed response can help identify rotating-force problems when position and phase context support them.
Looseness and support
Impacts, harmonics and location differences can reveal weak feet, pipe strain effects or structural looseness.
Hydraulic excitation
Broadband or vane-related vibration that changes with duty can point the investigation toward hydraulic behaviour.
Resonance and amplification
A modest forcing input can become severe when the pump, base or pipework responds near a structural resonance.
Measurement strategy
Measure the pump train, not one isolated point
Typical measurements cover the motor and pump bearing housings, with coupling-side, base or structural points added when needed. Flow, pressure, valve position or other operating details are valuable when vibration changes with process state.
On-site vibration analysis: measurements are taken while the machine is operating in a representative condition where safe access allows, with the operating condition recorded alongside the readings.
What you receive
Engineering output for a maintenance decision
You receive a concise engineering finding that connects the pump-train measurements to the most useful bearing, alignment, support, process or follow-up maintenance action.
A clear finding on the dominant vibration behaviour
Measurement locations and operating state documented
Mechanical versus process-sensitive clues separated where possible
A practical action list for inspection, correction, process review or recheck
On-site process
A focused vibration investigation
The visit records the operating point alongside each useful measurement so the mechanical finding is not separated from the process condition that produced it.
Confirm duty and symptom
Record pump type, speed, operating point, recent work and what has changed.
Measure motor and pump
Capture comparable readings at relevant bearing and support locations.
Separate mechanisms
Compare running-speed, harmonic, bearing, vane-related and structural evidence.
Recommend the next step
Direct attention toward the most useful mechanical, process or monitoring action.

Snapshot first, monitoring when time adds value
A changed pump can start with a snapshot. Continuous monitoring is useful where process state varies, the asset is critical or bearing/mechanical behaviour needs to be trended over time.

Questions
Pump vibration FAQs
Practical answers to common questions before an on-site diagnostic.
Can vibration analysis diagnose cavitation?
Vibration can provide useful cavitation-like or hydraulic-excitation evidence, especially when it changes with operating point. Process information such as flow, pressure and suction conditions helps confirm the hydraulic cause.
Do you measure the motor as well as the pump?
Yes. The motor, coupling and pump form one rotating train, so comparing both sides often makes the diagnosis much stronger.
Is a snapshot useful after a pump overhaul?
Yes. A post-maintenance snapshot can check the returned machine state and provide a useful reference for later comparison when operating conditions are repeatable.
