API 610 is the American Petroleum Institute’s standard for centrifugal pumps used in the petroleum, petrochemical, and natural gas industries. Known globally as the benchmark for heavy-duty process pumps, the 13th Edition, published in November 2021, represents the latest evolution in pump design, safety, and reliability.

This edition replaces the 12th Edition (2010) and its errata. While it maintains the core philosophy of previous versions, the 13th Edition introduces significant technical updates regarding rotor dynamics, seal chambers, and bearing life calculations to align with modern engineering practices and industry feedback.

  • BB (Between Bearings): The impeller is located between the bearings.
  • VS (Vertical): Vertical suspended pumps.
  • In the high-stakes environment of the oil, gas, and petrochemical industries, equipment reliability is not just a goal—it is a necessity. A single pump failure can result in costly downtime, environmental hazards, and safety risks. For decades, the benchmark for reliability in this sector has been API 610.
