Below is a guide to the key changes and technical updates in the 12th Edition. 1. Significant Technical Changes Removal of Design Life:

The 11th Edition's 20-year design life and 3-year uninterrupted operation requirements were removed. Manufacturers must now advise in their proposals of any components designed for a finite life Field Proven Model: Equipment must now be "field proven" as defined by the purchaser. The standard references API RP 691

for risk-based machinery management, particularly for high-risk services like those with hazardous liquids or low specific gravity (<0.5). Parallel Operation:

For pumps with discharge nozzles larger than 3 inches (80 mm), head values must be within

of each other when operating in the preferred region. This prevents one pump from "pushing" another back to shut-off. Mandatory Shaft Guards: In addition to coupling guards, shaft guards

are now mandatory to cover the exposed shaft area near the mechanical seal gland. Hydrocarbon Processing 2. Design and Component Updates Baseplate Requirements:

Standardized single-piece baseplates for horizontal pumps now include specific options for sloped deck plates and tapped drain connections (at least NPS 2). Piping Gusseting: Gusseting for piping connections NPS 1 and smaller

(such as drains and vents) is now mandatory in two orthogonal planes to increase rigidity and prevent small-bore piping failures. Vertical Pump NPSH Datum:

The NPSH3 datum elevation for vertically suspended and vertical inline pumps has changed from the "top of foundation" to the "impeller suction eye," ensuring consistency with horizontal pumps. Hydrocarbon Processing 3. Testing and Materials Increased Performance Test Points: The number of performance test points has increased from

to better verify the pump curve between rated flow and minimum continuous stable flow. Material Class Revisions: Cast Iron (I-1, I-2) and Ni-Resist (S-1, S-3)

classes have been removed as they are rarely used for modern API pressure casings. Duplex and Super Duplex

materials for pressure castings are now defined under standard (replacing A890). 12% Chrome Shafts are now required for S-6 materials. Hydrocarbon Processing 4.

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:

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
