Measurement of Pressure Pulsations and Vibrations

We conduct a detailed measurement of pressure pulsations and vibrations in and around your system, analyze your process parameters, and advise you on possible solution strategies. You will then receive a comprehensive measurement report.

Does your pump need to pass through certain speed ranges quickly? Are there cracks in weld seams? Can the pump be heard even outside the building?

Pressure pulsations originating from the pump are a potential cause of vibrations and limited operation.

Pressure Pulsations

Pressure pulsations are fluctuations superimposed on the static system pressure. Just like sound waves travel through air, pressure pulsations propagate through the pumped medium. Every pump inherently generates pressure pulsations due to its operating principle. Additionally, flow-related phenomena at valves and piping components can also lead to pressure pulsations.

These pressure fluctuations can excite vibrations in pipelines, valves, machines, or system components — potentially with damaging consequences.

With our high-resolution measurement equipment, we capture every pulsation and analyze its spectral composition. This allows us to identify the source of the pulsations and determine what can be done to mitigate them.

Vibrations

Pressure pulsations subject the piping structure to alternating loads, causing vibrations and oscillations. This leads to material fatigue and, in the worst case, can result in cracks or fractures. Through pipe supports and hangers, these vibrations are transmitted to the building structure. Depending on the frequency, the vibrations can also generate audible airborne noise, which is often perceived as disturbing.

We measure vibrations on pumps and pipelines in all three spatial directions. This allows us to correlate pressure pulsations with structural vibrations and establish a clear link between cause and effect.

Operational Vibration analysis

By measuring vibrations at different positions, the movement of the structure (e.g., a pipeline) can be precisely reconstructed. We make resonance visible.

This allows us to assign excitation mechanisms to specific motion patterns and to identify and isolate relevant and harmful operating conditions.

Based on this information, we determine the best solution strategy for your system.

Hydrobox

With our Hydrobox, we offer you a straightforward way to perform ad hoc measurements of pipeline vibrations in all three spatial directions. This provides an initial assessment of your system.

Simply strap it onto the pipeline and start. The Hydrobox is self-contained and automatically runs a measurement program—no additional configuration required.

You can rent the Hydrobox and carry out measurements independently. We will evaluate the data and provide you with feedback.

Alternatively, we’re happy to visit you on-site. You show us your system, and the Hydrobox records initial measurements in the background.
