While this is a worthwhile investment for a certified repair shop, many individual technicians, small workshops, or students search for for educational or reference purposes.

API 610 defines strict minimum running clearances between rotating and stationary wear rings. If clearances exceed 150% of the initial design value, the rings must be replaced.
Detailed tolerances and acceptance criteria for cleaning, non-destructive testing (NDT), and manufacturing new parts.
API 697 works in tandem with API 610 (the definitive standard for centrifugal pumps) and API 682 (the standard for pumps mechanical seals). While API 610 governs how a pump is built, API 697 governs how it is restored after years of service. Core Phases of Industrial Pump Repair
