The standard divides pump vibration severity into four zones:
Rotodynamic pumps are the workhorses of industrial fluid transport. Unlike general machinery standards (like ISO 10816-3), Part 7 is specifically tailored to the unique hydraulic and mechanical forces found in pumps. ludeca.com
The vibration of newly commissioned or freshly overhauled machines typically falls within this zone. The pump is operating optimally.
Machines with vibration within this zone are normally considered acceptable for unrestricted long-term operation. iso 10816-7 pdf download

, titled " Mechanical vibration — Evaluation of machine vibration by measurements on non-rotating parts — Part 7: Rotodynamic pumps for industrial applications, including measurements on rotating shafts ," is an international standard that specifies guidelines for measuring and evaluating vibration.
Applies to rotodynamic pumps for industrial use with power above 1 kW.
Many authorized online platforms resell standards. These websites provide easy search, instant PDF download, and often have multilingual support. Some examples include: The pump is operating optimally
Proper execution of the vibration measurement is as important as understanding the evaluation criteria. ISO 10816-7 outlines specific procedures to ensure reliable and comparable results.
| Standard | Purpose | |----------|---------| | | General guidelines for all machinery | | ISO 20816-7 | Updated framework (supersedes 10816-7? No – 20816 series is for larger machines) | | API 610 | Centrifugal pumps for petroleum industry (stricter than ISO) | | ISO 2954 | Specifies vibration meter characteristics | | ISO 13373-1 | Vibration condition monitoring techniques |
In industrial maintenance, monitoring machine health is essential to prevent costly downtime. Vibration analysis is a primary method used to assess the condition of rotating machinery. For engineering professionals, reliability managers, and procurement specialists, is the definitive international standard governing vibration evaluation for rotodynamic pumps.
