Reply to "Vibration at 5X NDE AND DE V for Centrifugal Pump"

Greetings team

 

Very Interesting case. only 5X dominating. No problems noticed in spectrum. All unique components are in good condition.  

3.84 mm/s at 5X is still in normal condition. However, the cause of 5X dominant can appear due to flow conditions like impeller stall. 

 

Check the pump suction and delivery valves, system flow conditions (full flow or throttled flow) Load on motor etc.,

Pleased to see such isolated case.

 

regards

Chary
