These pumps are permitted slightly higher vibration levels compared to Category I machinery. Vibration Evaluation Zones

ISO 10816-7:2009 is the international standard specifically for evaluating the mechanical vibration of rotodynamic pumps

Unrestricted Long-Term Operation. Pumps exhibiting Zone B vibration levels are considered acceptable for continuous, long-term operation without risk of damage. The official standard , which specifies vibration evaluation

Focuses on measurements taken on non-rotating parts (bearing housings) and, where applicable, on rotating shafts . Evaluation Criteria: Defines two main criteria: Magnitude: The absolute level of vibration. Change in Magnitude: The trend of vibration over time.

Distinguishes between pumps above and below 200 kW for certain evaluation criteria. Pumps exhibiting Zone B vibration levels are considered

: Unlike other parts of the ISO 10816 series, Part 7 specifies limits for both horizontal and vertical pumps regardless of their support flexibility (rigid vs. flexible). Pump Categorization

Setting operational limits for acceptance testing and operational monitoring. Pump Categorization Under the Standard

Searching for is the first step toward better pump reliability. While there’s no legal free lunch, the official document is a worthwhile investment compared to the cost of a catastrophic pump failure. Use the standard alongside vibration analyzers and root cause analysis to keep your rotodynamic pumps running in Zone A or B.
