This standard provides instructions for evaluating the vibration of rotodynamic pumps for industrial applications. Scope: Applies to pumps with nominal power above 1 kW.
Measurements: Primarily focuses on vibration measurements made on non-rotating parts, such as bearing housings.
Applications: Used for in-situ operational monitoring, factory acceptance tests, and general diagnostics.
Classification: Distinguishes between pumps above and below 200 kW for certain evaluation criteria.
Current Status: The 2009 version remains the current standard, though a successor (ISO 20816-7) is currently under development. Evaluation Zones
The standard classifies vibration severity into four zones to help engineers determine machine health:
Zone A: Vibration of newly commissioned machines (excellent). Zone B: Acceptable for unrestricted long-term operation. Zone C: Acceptable for limited operation only. Zone D: Dangerous levels; risk of damage to the machine. Where to Purchase and Download ISO 10816-7:2009 - Mechanical vibration

The ISO 10816-7:2009 standard is the essential global benchmark for evaluating the mechanical vibration of rotodynamic pumps. Whether you are a reliability engineer or a maintenance manager, understanding how to apply these criteria is critical for ensuring pump longevity and preventing catastrophic failures. What is ISO 10816-7?
ISO 10816-7 provides specific instructions for evaluating vibration measured on non-rotating parts, such as bearing housings, for industrial rotodynamic pumps with a nominal power above 1 kW.
Unlike more general standards, this part of ISO 10816 is tailored specifically to the unique hydraulic and mechanical characteristics of pumps. It covers both horizontal and vertical pumps and is used for: Operational monitoring of pumps in situ. Factory acceptance tests at the manufacturer's facility. Setting Alarm and Trip thresholds to prevent damage. Key Measurement Parameters
To comply with the standard, measurements must follow these technical requirements:
Primary Quantity: The root-mean-square (r.m.s.) vibration velocity in mm/s. A: No legally
Frequency Range: Typically 10 Hz to 1,000 Hz. For low-speed pumps (below 600 r/min), the range should extend down to 2 Hz, and peak-to-peak displacement ( ) must also be measured.
Pump Categories: The standard distinguishes between two main application types:
Category I: Pumps for high-reliability or critical applications (e.g., hazardous liquids, chemical, or power plants).
Category II: Pumps for general or less critical industrial applications. Evaluation Zones and Limits
ISO 10816-7 classifies vibration levels into four "evaluation zones":
Zone A: Vibration of newly commissioned machines (typically within the preferred operating range).
Zone B: Machines considered acceptable for unrestricted long-term operation.
Zone C: Machines considered unsatisfactory for long-term continuous operation, though they may operate for a limited period until maintenance can be performed.
Zone D: Vibration levels high enough to cause immediate damage to the machine. 1st ISO/CD 10816-7 "Mechanical vibration
ISO 10816-7 is the international standard specifically governing the mechanical vibration of centrifugal pumps for industrial applications. It defines the procedures and guidelines for measuring and evaluating vibration on non-rotating parts (like bearing housings) during steady-state operation. Overview of ISO 10816-7
This standard provides distinct criteria for assessing vibration levels based on the pump's power, reliability requirements, and installation type. It is widely used by maintenance engineers and plant operators to ensure equipment longevity and safety.
Scope: Covers centrifugal pumps for industrial use with nominal power above 1 kW.
Measurement Metrics: Focuses on vibration velocity (expressed in mm/s or in/s RMS). This metric is the best indicator of the overall "energy" of the vibration and its potential to cause structural fatigue. Pump Categorization:
Category I: Pumps requiring high reliability, availability, or safety (e.g., hazardous toxic liquids, critical power plant pumps).
Category II: General-purpose industrial pumps where downtime is less critical. Vibration Evaluation Zones
The standard classifies vibration severity into four colored zones, which help in deciding the necessary maintenance action:
Zone A (Green): Vibration of newly commissioned machines; considered excellent.
Zone B (Yellow): Machines considered acceptable for unrestricted long-term operation.
Zone C (Orange): Machines considered unsatisfactory for long-term continuous operation; remedial action should be planned. Need help interpreting ISO 10816-7 vibration limits for
Zone D (Red): Vibration levels are high enough to cause immediate damage; the machine should be shut down. How to Access the PDF

Using ISO 10816-7 allows for a standardized language between pump manufacturers and end-users. Instead of subjective "feel," it provides empirical limits that help prevent catastrophic bearing failures, seal leaks, and shaft issues.
ISO 10816-7 is a critical international standard for engineers and maintenance professionals, as it provides the framework for evaluating vibration in rotodynamic pumps www.iso.org
If you are searching for a "PDF download," it is important to note that this is a copyrighted document. While various "preview" versions exist online, the full, official document must be purchased to ensure legal compliance and accuracy for industrial audits. The Role of ISO 10816-7 in Industry
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 standard's primary purpose is to distinguish between "normal" operation and vibration that signals an imminent failure. It is widely used for: www.europump.net Factory Acceptance Tests (FAT): Proving a new pump meets quality standards before shipping. Condition Monitoring:
Tracking the "health" of a pump over time to prevent unplanned downtime. Predictive Maintenance:
Setting "Alarm" and "Trip" thresholds based on internationally recognized data. www.iso.org Key Technical Specifications
The standard categorizes pumps into two main groups to provide appropriate vibration limits: www.europump.net Category I:
High-reliability or critical service pumps (e.g., handling hazardous or toxic liquids). Category II:
General-purpose pumps (e.g., water pumps for non-hazardous liquids). www.europump.net Measurement Parameters Measurement Type:
Primarily focuses on root-mean-square (RMS) vibration velocity (measured in mm/s) on non-rotating parts like bearing housings. Frequency Range:
Typically 10 Hz to 1,000 Hz, though this can vary for very low-speed or high-speed pumps. Evaluation Zones: Results are classified into four zones: (newly commissioned), (acceptable for long-term use), (unsatisfactory for long-term use), and (serious risk of damage). www.europump.net Where to Legally Download the ISO 10816-7 PDF
