While many standards focus solely on bearing housing vibration, ISO 10816-7 recognizes that for certain high-speed or large industrial pumps, shaft vibration measurements are critical. Measured in mm/s RMS.
Understanding ISO 10816-7: The Standard for Rotodynamic Pump Vibration iso 10816-7 pdf download
ISO 10816-7 specifically covers industrial pumps with a power rating above 1 kW. It applies to: Centrifugal pumps Mixed-flow pumps Axial flow pumps Pumps integrated with their drivers (monoblock pumps) Vertical and horizontal pump configurations What is Excluded?
Measurement on non-rotating parts like bearing housings. : A reliable provider of German and international standards
Measured in millimetres per second (mm/s) Root Mean Square (RMS). This is the primary metric used to detect general structural and mechanical issues. Vibration Displacement: Measured in micrometres (
Structures (like skids or steel mezzanines) where the support system flexes or has a natural frequency close to or below the operating speed. Pumps on flexible foundations are generally allowed slightly higher vibration limits because the structure absorbs and amplifies some of the energy without necessarily damaging the pump internals. 3.

Is the pump mounted on a or a flexible steel framework ?
