Hello;

I was wondering why the harmonics appeared in the spectrum.
In the case where there is a looseness in the base, the dominant peak is usually at 1X without harmonics.

Thanks in advance.

Hi benson

The pump itself was fine. After attempts at checking alignment, basic structural checks no improvement made. Yes the camera nailed it with the base plate having insufficient support (therefore stiffness) in the middle, clearly seen with MA (seems obvious but they’d checked the holding down bolts).
