    Question HELP required for pump vibration analysis.

    I want help in vibration analysis field.

    Recently i have fond vibration signature analysis for a pump throgh FFT as per attachment.
    The pump is a hydraulic oil service, straight lobe type, verically submerge in sump, coupled with motor by
    spider coupling. RPM is 1445. Electrcal motor driven.

    It is showing piks at 1X and 10X RPM frequency in vibration analysis. The other stand-by pump is OK.

    Can anybody working with vibration help me identify the problem with pump?

    Vibration is high on axial as well as on radial orientation. Please find attachment herewith.

    Vijay
