API 610 does not itself specify detailed mechanical seal designs; that role belongs to (“Pumps – Shaft Sealing Systems for Centrifugal and Rotary Pumps”). However, API 610 requires that seals and flush plans be selected in accordance with API 682. Typical seal leakage limits are set at ≤ 100 ppm (by volume, for light hydrocarbon services).

By understanding and implementing the requirements of API 610 13th Edition, pump users and manufacturers can work together to improve pump performance, reliability, and safety, while reducing costs and environmental impact. API 610 does not itself specify detailed mechanical

for additively manufactured (3D-printed) metallic components [19]. Why does this matter?
API 610 imposes strict limits on bearing housing vibration to ensure mechanical integrity and long service life. For overhung pumps, the overall vibration shall be less than for the overall frequency, and less than 2 mm/s (0.08 in/s) for discrete (synchronous) frequencies. For between‑bearings pumps, similar but sometimes differentiated limits apply. Outside the preferred operating region, vibration levels may not exceed 30 % of these limits during performance testing.
While the merger with API 685 remains a future possibility, the 13th Edition draft makes clear that API 610 will continue to serve as the cornerstone for sealed centrifugal pump applications. For engineers, procurement specialists, and maintenance professionals, understanding the forthcoming changes is not merely an academic exercise—it is essential preparation for specifying, buying, operating, and maintaining pumps that must deliver decades of safe, reliable service in some of the world’s most demanding environments.
