Reply to "High vibration on centrifugal pump"

We have some of these "Amine"  pumps at an oil refiner, and they all show a 3x. I have never seen or heard what the blade count is, but it looks like 3 in our pumps. I think I will ask around next time we are there.

I will attach a spectrum later.

Thanks.

Dear Ralph, 

 

I think so,  that vibration came out from blade pass.  ��

Thank you for your information,  that is really help me.
