API SEAL PLAN DESIGN & INSTALLATION

OUR SERVICESENGINEERED SEALING SOLUTIONS FOR RELIABLE PUMP OPERATION

CONTROL LEAKAGE. PROTECT EQUIPMENT. EXTEND SEAL LIFE.

Mechanical seal failures are often caused not by the seal itself, but by improper sealing conditions—such as inadequate cooling, contamination, pressure imbalance, or dry running.

Our API Seal Plan Design & Installation service provides engineered solutions based on API standards to ensure proper sealing conditions, improve reliability, and extend equipment life.

WHY DO YOU NEED AN API SEAL PLAN?

Mechanical seals operate under demanding conditions. Without proper support systems, they are prone to premature failure.

Seal plans are designed to solve multiple operational problems, including:

  • Overheating of seal faces
  • Dry running conditions
  • Contamination of sealing surfaces
  • Pressure imbalance across the seal
  • Product leakage and environmental risks
  • Reduced seal life and repeated failures

👉 A properly designed seal plan ensures the seal operates under controlled, optimal conditions.

COMMON APPLICATIONS & API PLAN EXAMPLES

Depending on the process, fluid, and operating conditions, different API Seal Plans are applied:

  • API Plan 11 – Internal recirculation for clean fluids
  • API Plan 32 – External flush for dirty or solids-laden fluids
  • API Plan 52 – Unpressurized dual seal system for containment
  • API Plan 53 – Pressurized barrier system for hazardous fluids
  • API Plan 54 – External pressurized system for critical applications

👉 Each plan is selected based on fluid characteristics, pressure, temperature, and reliability requirements.

IDEAL FOR
  • Pumps with recurring mechanical seal failures
  • Systems handling dirty, hazardous, or high-temperature fluids
  • Applications requiring improved seal reliability and safety
  • Facilities upgrading from packing to mechanical seals
  • Clients requiring API-compliant sealing systems

⚠️ LIMITATIONS OF SERVICE

Final design and installation scope may vary depending on site conditions, available space, and system configuration.
Additional fabrication or modification works may be required based on actual installation requirements.

TOOLS & EQUIPMENT

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

  • Mechanical installation tools
  • Pipe fitting and fabrication tools
  • Alignment and measurement tools
  • Pressure and leak testing tools
  • Inspection and documentation tools

✔ Tools may be adjusted depending on site conditions and accessibility

MANPOWER & EXECUTION

  • Mechanical Technicians (Seal and Pump Specialists)
  • Supervising Engineer (Design and QA)
  • Fabrication support (as required)

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

ESTIMATED DURATION

  • Design and engineering: depends on complexity
  • Installation: typically 3–7 days
  • Commissioning: same day as installation or as required

✔ Duration may vary based on:

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

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.
