Detect mechanical defects like unbalance, misalignment, or loose components before catastrophic failure occurs.

The standard divides pump vibration severity into four zones:

The standard's primary focus is on rotodynamic pumps used in industrial applications with a nominal power exceeding 1 kW (kilowatt). It defines specific requirements for evaluating vibration when measurements are taken on the non-rotating bearing housing. Notably, the standard is applicable to a wide range of pump installations, as it specifies vibration zones and limits for both horizontal and vertical pumps, irrespective of the flexibility of their support structure. iso 10816-7 pdf download

Assessing significant shifts in vibration levels from a baseline, which often indicates developing faults even if absolute limits haven't been reached. Machine Categorization and Zones

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. Notably, the standard is applicable to a wide

One valuable resource is the availability of free online tools, such as the "Free ISO Vibration Severity Checker," which provides instant zone assessments (A/B/C/D) and explains the severity ratings for pumps in compliance with ISO 10816-7 and industrial machines under ISO 10816-3.

Establish clear vibration limits divided into operational zones. While there’s no legal free lunch, the official

A single high reading is cause for investigation. A rising trend from Zone B to Zone C is actionable even before crossing the limit. Use the standard’s guidance on “operational duration” in Zone C (typically limited to 1–3 months).
