Api 610 13th Edition May 2026
As of early 2026, API 610 13th Edition has not been officially released, with the January 2021 12th Edition remaining the active standard. While development for the next iteration is expected in the mid-2020s, current industry focus remains on the 12th edition's requirements for enhanced venting and alignment with API 691.

Recommendation: If you sell into North America or the Middle East, use API 610 13th Edition. For European projects, reference ISO 13709 but add a "supplement" requiring API 13th compliance for vibration and seals.
The API 610 13th Edition, with drafting active as of late 2024, continues to establish stringent standards for centrifugal pumps in petroleum and natural gas industries, building upon the 12th Edition's focus on reliability and material optimization. Key updates involve specific requirements for floating applications, mandatory shaft guards, and stricter NPSH3 definitions, while maintaining core OH, BB, and VS classifications. For technical documentation, review the API 610 draft specifications. Api 610 13th Edition
Manufacturers can label pumps as complying with both API 610 13th / ISO 13709.
Regardless of the edition, API 610 maintains a rigorous classification for centrifugal pumps: Pump piping Forces & Moments - how much is too much ? As of early 2026, API 610 13th Edition
3.3. Mechanical Seal Support Systems
- Adoption of API 682 5th edition references (seal piping plans, quench arrangements).
- Clarification on flush plans for high-temperature hydrocarbons (Plan 23, 52, 53B/C) to reduce coking and seal face overheating.
New: Optional Thermal Growth Verification Test for pumps with operating temperature > 250°C (measure cold-to-hot alignment shift).
Enhanced Reliability Controls: Stricter mandates for vibration control and bearing reliability to minimize unplanned downtime in high-stress environments. Adoption of API 682 5th edition references (seal
API 610 13th Edition is currently under development by the API 610 Task Force
