Maintenance & Repair Process
Mechanical Seal

KLE engineers carefully disassemble the complete mechanical seal assembly to support detailed inspection and refurbishment activities. The disassembly procedure is performed in accordance with technical standards to prevent secondary damage to components.

All components are cleaned using ultrasonic cleaning equipment together with specialized cleaning solutions to effectively remove oil residue, deposits, and contaminants from surfaces and narrow internal gaps that conventional cleaning methods cannot fully access.

After cleaning, each component is thoroughly inspected and evaluated, including seal faces, O-rings, springs, and other critical parts. Inspection findings are documented in a detailed technical report to support condition assessment and repair recommendations.

Seal faces are precision-machined using specialized lapping equipment to restore surface flatness and improve sealing performance. This process ensures the sealing surfaces meet the required technical specifications.

Optical flat equipment and monochromatic light are used to inspect the flatness of sealing surfaces through Lightband measurement. The obtained results are utilized to verify machining accuracy and surface condition.

Qualified components are reassembled in a controlled cleanroom environment. The assembly process is carried out in accordance with technical standards to ensure proper fitment, dimensional accuracy, and concentric alignment.

Following assembly, the seal is subjected to pressure and performance testing under conditions simulating actual operating environments. All testing results must comply with API 682 requirements before release to the next stage.

The seal is packed under controlled conditions to ensure cleanliness and protect sealing surfaces during handling and transportation. Each product is delivered together with the corresponding technical inspection report and warranty documentation.
