Seasonal environmental changes can significantly impact pump and motor behavior—sometimes in ways that aren’t immediately obvious. In this recent case, Hydro’s Centaur IIoT monitoring platform continuously tracked vibration data on a vertically mounted pump-motor system operating in a cold climate region.
While the system showed no overt performance issues, long-term data revealed that motor vibration amplitudes consistently increased 150–200% during colder months. Frequency analysis identified discrete peaks linked to transient cavitation events and turbulence, particularly on the pump and recirculation line.
Thanks to Centaur’s high-resolution, 24/7 monitoring, the issue was diagnosed without unnecessary shutdowns or false alarms. The facility team was able to schedule targeted inspections and maintenance during routine downtime, safeguarding equipment health and avoiding costly interruptions.
This case highlights how continuous condition monitoring delivers insights that periodic manual checks might miss—especially in environments with fluctuating ambient conditions.
