PUMP FAULT ANALYSIS & CORRECTIVE REPAIR

OUR SERVICESIDENTIFY THE ROOT CAUSE. FIX THE DAMAGE. PREVENT IT FROM HAPPENING AGAIN.

RESTORE PERFORMANCE. ELIMINATE REPEAT FAILURES.

When a pump fails, replacing damaged parts alone is not enough. Without identifying the root cause, the same failure can happen again—leading to repeated downtime and increasing maintenance costs.

Our Pump Fault Analysis & Corrective Repair service focuses on understanding why the failure occurred, performing the necessary repairs, and ensuring that corrective actions are implemented to prevent recurrence.

WHY DO YOU NEED FAULT ANALYSIS?

Most pump failures are symptoms—not the root problem.

Common situations where this service is critical:

  • Repeated failure of mechanical seals or bearings
  • Unexpected breakdown of a previously working pump
  • Newly repaired pumps failing again
  • Severe vibration or overheating prior to failure
  • Unknown cause of equipment damage

Without proper analysis, repairs become temporary fixes rather than long-term solutions.

COMMON FAILURE MODES IDENTIFIED

This service investigates damage related to:

  • Bearing failure (wear, overheating, contamination)
  • Mechanical seal failure (leakage, face damage, improper installation)
  • Shaft damage or excessive runout
  • Impeller wear, erosion, or imbalance
  • Cavitation-related damage
  • Misalignment and soft foot issues
  • Pipe strain and external loading
  • Lubrication failure or contamination
IDEAL FOR
  • Pumps that have already failed or are non-operational
  • Systems with recurring breakdowns
  • Critical equipment requiring root cause determination
  • Clients seeking long-term reliability, not just repair
  • Industrial and process pump systems

  • Assessment of mechanical seal condition
  • Bearing inspection and damage profiling
  • Identification of wear patterns and failure characteristics
2. Damage Profiling & Root Cause Analysis
  • Evaluate condition of all critical components
  • Identify failure patterns and contributing factors
  • Determine likely root cause of failure
  • Assess influence of operation, installation, and environment
3. Corrective Repair Works
  • Replacement of damaged components (bearings, seals, etc.)
  • Shaft repair or replacement (if required)
  • Cleaning, restoration, and reassembly of pump
  • Correction of identified issues affecting performance
4. Alignment & Installation Correction
  • Check and correct alignment condition
  • Address soft foot and base issues
  • Evaluate pipe strain and installation condition
  • Ensure proper reinstallation of the pump system
5. Preventive Recommendations
  • Provide recommendations to prevent recurrence of failure
  • Suggest improvements in operation, maintenance, or installation
  • Recommend upgrades or design adjustments if necessary
⚠️ LIMITATIONS OF SERVICE

Extent of repair depends on condition of equipment and availability of replacement parts.
Additional machining, fabrication, or specialized repair services may be conducted separately as required.

TOOLS & EQUIPMENT

The activities will be conducted using standard and field-proven tools to ensure accurate and reliable assessment:

  • Standard dismantling and mechanical tools
  • Bearing and seal handling tools
  • Measurement tools (runout, alignment, etc.)
  • Cleaning and inspection equipment
  • Lifting tools (as required depending on pump size)

✔ Tools may be adjusted depending on site conditions and accessibility

MANPOWER & EXECUTION

  • Mechanical Technicians (Pump Specialists)
  • Supervising Engineer
  • Additional manpower for dismantling and heavy handling (if required)

✔ Execution will be coordinated with site personnel to ensure safe and efficient activity

ESTIMATED DURATION

  • Inspection and dismantling: 1–3 days
  • Repair and reassembly: depends on damage and parts availability
  • Total duration varies based on pump condition and complexity

✔ Duration may vary based on:

  • Number of pumps
  • Accessibility of equipment
  • Operational conditions (running vs shutdown)

STANDARDS & PRACTICES

Our pump inspection and evaluation services are performed in accordance with internationally recognized standards and proven industry practices to ensure accuracy, reliability, and safety.

We align our work with:

  • API Recommended Practices – for equipment reliability and oil & gas applications (where applicable)
  • ISO Standards – for structured maintenance and quality management systems
  • ASTM Standards – for material evaluation, testing, and inspection procedures

DELIVERABLES

After the inspection, a Service Report covering the full scope of work performed will be provided. This report serves as a formal documentation of findings, assessment, and recommended actions.

The report includes:

  • Comprehensive Inspection Report
    A detailed summary of the pump’s overall condition, covering mechanical, operational, and installation aspects
  • Findings with Severity Classification
    Identified issues categorized by risk level (Critical / Moderate / Minor) to support prioritization
  • Root Cause Observations
    Initial analysis of probable causes (e.g., misalignment, cavitation, wear, improper installation)
  • Recommended Corrective Actions
    Practical and prioritized recommendations for repair, adjustment, or further diagnostics
  • Photo Documentation
    Clear visual evidence of findings for validation and internal reporting
  • Operational Condition Assessment
    Evaluation of current operating behavior (vibration, noise, temperature, flow indicators where applicable)
  • Maintenance Recommendations
    Suggested preventive maintenance actions and monitoring intervals
  • Repair & Upgrade Recommendations (if required)
    Guidance on whether repair, replacement, or system improvement is more appropriate

PROJECT CONSIDERATIONS & CONSTRAINTS

The execution of the service is subject to site accessibility, operational conditions, and required safety clearances. All equipment and work areas must be reasonably accessible to allow proper inspection, assessment, or execution of the agreed scope. Certain activities may require the equipment or system to be operational, while others may necessitate partial or full shutdown, depending on the nature of the work.

All necessary permits to work (PTW), safety clearances, and site approvals must be secured prior to execution to avoid delays. Coordination with site personnel is required to ensure safe and efficient completion of activities. The provision of site support such as access equipment, manpower assistance, utilities, and isolation (if required) shall be the responsibility of the client unless otherwise agreed.

Environmental and site conditions, including but not limited to weather, confined spaces, hazardous areas, and operational limitations, may affect the execution schedule and duration of the service.

ASSUMPTIONS

The service is based on a non-intrusive approach and is limited to externally accessible components and observable conditions unless otherwise specified in writing. No dismantling, internal inspection, or major repair works are included under this scope unless explicitly stated.

All findings, assessments, and recommendations are based on the condition of the equipment or system at the time of service and on available operational data provided or observed. Recommendations are intended to support maintenance, operational, and engineering decisions but do not constitute a certification of equipment integrity, performance, or regulatory compliance.

Any additional works identified during the execution of the service that fall outside the agreed scope may be subject to separate evaluation, costing, and approval.

Note: The indicated scope, exclusions, and duration are preliminary and may be adjusted following detailed assessment of site conditions, operational constraints, and project-specific requirements.
