1. Revised Classification of Pump Types
The 12th edition refines the definitions of Overhung (OH), Between-Bearing (BB), and Vertically Suspended (VS) pumps. For instance:
- OH6 (high-speed integral gear pump) specifications have been made more stringent.
- BB5 (vertical barrel-inlet, double-case) pumps now have clearer axial thrust balance rules.
What is API 610?
API 610 is a standard published by the American Petroleum Institute (API). It specifies requirements for centrifugal pumps designed for use in general refinery services, heavy-duty chemical plants, and pipeline transfer applications.
The standard is not merely a suggestion; in most major oil and gas projects, compliance with API 610 is a mandatory contractual requirement. It dictates everything from hydraulic performance and mechanical design to material selection and testing protocols.
Safety and Reliability
Non-API pumps may use thinner casings or lighter-duty bearings to save cost. In a refinery, where a pump might be moving toxic or flammable fluid at 300°C, a casing failure could be catastrophic. API 610 mandates robust
The API 610 12th Edition, released in January 2021, is the definitive standard for centrifugal pumps in the petroleum, petrochemical, and natural gas industries. This update marks a significant shift from previous editions, notably ending the "co-branding" relationship with ISO 13709 and prioritizing US Customary Units. Key Reliability & Maintenance Updates
The 12th Edition focuses heavily on field performance and long-term reliability rather than theoretical design lives.
Field Proven Model: The rigid "20-year design life" from the 11th Edition has been replaced with a requirement for field-proven equipment. It now references API RP 691 for risk-based machinery management, especially in hazardous or high-temperature services.
Parallel Operation: For pumps with discharge nozzles larger than 3 inches (
), the standard now mandates that head values must be within 3% of each other in the preferred operating region to prevent "pushing" a pump to shut-off.
Mandatory Gusseting: Rigid orthogonal gusseting is now mandatory for casing connections (vent and drain) of NPS 1 and smaller to prevent vibration-induced fatigue failures.
Enhanced Testing: Performance tests now require 9 points of measurement (up from 6) to better define the pump's performance curve, including points at the ends of both preferred and allowable operating regions. Design & Component Changes
Vented Shaft Guards: A new mandate requires shaft guards (not just coupling guards) that are vented to prevent the buildup of vapors and allow for visual inspection of the seal without removal.
OH2 Auxiliaries: To improve maintenance access, auxiliaries for OH2 (overhung) pumps must now be mounted adjacent to the suction nozzle, keeping the area around the bearing housing and coupling clear. Material Revisions: api 610 12th edition pdf
Cast iron material groups (I-1 and I-2) have been removed and replaced with S5.
CA6NM is now mandated for 12% chrome impellers (replacing CA15) for better weldability and crack resistance.
Duplex material standards for pressure castings have shifted from A890 to A995. Where to Purchase or Access

The API 610 12th Edition, titled "Centrifugal Pumps for Petroleum, Petrochemical, and Natural Gas Industries," was officially released in January 2021. This latest edition represents a major update to the world’s foremost standard for centrifugal pumps, addressing modern industry needs for improved reliability, safety, and environmental performance. Core Scope and Applications
The standard specifies requirements for centrifugal pumps used in process services across the oil and gas sectors. It covers a wide range of pump types, which are traditionally categorized into three main groups: Report: Analysis of API 610 12th Edition (ISO
OH (Overhung): Impellers extend beyond the radial bearing support.
BB (Between Bearings): Impellers are located between the bearing supports.
VS (Vertically Suspended): Submerged pumps, including vertical can-type (VS6) and sump pumps. Key Changes in the 12th Edition
The transition from the 11th to the 12th edition took approximately eleven years, introducing several critical updates:
Departure from ISO Co-branding: Unlike previous versions, the 12th edition is no longer co-branded with ISO 13709. U.S. Customary Units are now the primary measurement, with metric values provided in parentheses.
Shaft Guarding: A significant safety update is the mandate for shaft guards around the mechanical seal area to protect personnel from exposed rotating parts.
Field Proven Model (API 691): The standard now emphasizes "field proven" equipment and references API 691 for risk-based machinery management, particularly for high-risk, hazardous, or high-pressure services.
Parallel Operation Requirements: For pumps operating in parallel with discharge nozzles larger than 3 inches (80 mm), head values must now be within 3% of each other in the preferred operating region to ensure stability.
Updated Testing Standards: Performance testing now requires 9 points instead of 6, ensuring better verification of the pump's curve between rated flow and minimum stable flow.
Baseplate & Piping Design: Standardized baseplate options have been revised, and gusseting for small-bore piping (NPS 1 and smaller) is now mandatory to prevent vibration-induced failures. Why These Updates Matter
Focusing on life-cycle costs is essential, as approximately 40% of a pump's total cost is driven by operation, maintenance, and downtime. By adopting the 12th edition standards, operators can expect better long-term mechanical integrity and reduced risk in critical applications. Official Documentation and Resources
