Ensuring Reliability & Peak Performance
Pumps, compressors, turbines, gearboxes, and blowers keep industrial operations moving—but heat, vibration, and wear take a toll. A disciplined repair program restores performance, prevents repeat failures, and protects uptime. Bunney’s Inc. services rotating equipment for power, water/wastewater, mining, and manufacturing facilities across Arizona and the Southwest.

What Rotating Equipment Repair Includes
-
Inspection & Diagnosis: Vibration and thermography surveys, oil analysis, NDT, performance testing
-
Precision Repairs: Bearing and seal replacement, shaft repair, impeller/rotor work, wear-ring and case restoration
-
Balancing & Alignment: Dynamic balancing (in-shop/on-site), laser alignment, soft-foot correction
-
Upgrades & Retrofits: Material upgrades, lubrication improvements, mechanical seal conversions, energy-efficiency tweaks
-
Controls & Start-up: Instrument checks, baseline parameters, run-in and post-repair verification
Repairs are executed on-site or in-shop depending on size, criticality, and access.
Common Failure Modes (and How We Address Them)
-
Bearing failures: Contamination, misalignment, or overload → root-cause analysis, clean fits, correct preload, lube optimization
-
Seal & gasket leaks: Heat/chemical attack → seal conversions, proper flush plans, surface restoration
-
Imbalance & misalignment: Vibration, noise, premature wear → dynamic balance and laser alignment with documented tolerances
-
Shaft damage: Fatigue/corrosion/score → shaft metal-spray, sleeve/replace, fit and concentricity verification
-
Wear & erosion: Abrasive service/high speed → hard coatings, upgraded materials, clearances to spec
-
Overheating: Poor lubrication/ventilation → lube audits, cooling improvements, venting and filtration fixes
Predictive & Preventive Maintenance (PdM/PM)
Stop failures before they start with data-driven maintenance:
-
Vibration analysis & trending
-
Oil sampling/ferrography for contamination and wear metals
-
Thermal imaging to catch friction/hot spots
-
Ultrasound for bearing and leak detection
-
Performance KPIs: flow/head, amps, temperature, vibration mm/s, MTBF/MTTR
We translate findings into a prioritized corrective action plan and schedule.
Arizona-Specific Considerations
-
High ambient heat: Bearing and motor cooling, heat shields, grease selection, insulation class checks
-
Dust/sand: Seal/filtration upgrades, ingress protection, cleanliness standards for assembly
-
Monsoon moisture: Corrosion control, drainage, enclosure integrity and coatings
-
Water chemistry: Scaling/erosion prevention for pumps and condensate service

FAQs
Can you balance equipment in place?
Yes—our teams perform in-situ dynamic balancing when removal isn’t practical, then verify with post-balance vibration readings.
How do you decide between repair and replace?
We compare repair scope, parts lead time, downtime cost, and expected life extension—then recommend the best lifecycle value.
What’s the typical cause of repeat bearing failures?
Often misalignment, contamination, or improper lubrication. We pair bearing replacement with alignment and lube program fixes to stop recurrence.
Do you support emergency breakdowns?
Yes—rapid response statewide with on-site diagnostics, critical spares coordination, and temporary workarounds where safe.
Will we get test data after the repair?
Absolutely—as-left vibration, temperature, and performance data, plus alignment/balance reports and parts documentation.
