Api 610 13th Edition Jun 2026

Each shaft shall be supported by two radial bearings and one double-acting axial (thrust) bearing to maintain structural stability and accommodate the axial thrust generated by the impeller. Additionally, bearing housings must be designed with:

The API 610 standard outlines the baseline engineering, testing, and materials requirements for process pumps. Unlike dimensional specifications like ANSI B73.1 , API 610 focuses heavily on structural integrity and performance safety . It dictates how pumps must handle extreme pressures, volatile fluids, and thermal expansion. Api 610 13th Edition

Even as appendices are reorganized, the fundamental technical requirements that make API 610 the “gold standard” for heavy‑duty pumps will remain largely intact—and in some cases, become even more rigorous. Each shaft shall be supported by two radial
