    Might be bad bearings in the motor if it has them.

    Add rubber between pump and metal and put some heavy weight on the metal, changes the sound to much more pleasant humming.

    If impeller type, make sure that nothing is jammed/stuck to the impeller or a broken blade causing off balance vibration.
    Max.

    Noise Coolant Pump

    This is on a Nardini Lathe with 3 phase. The coolant pump is loud enough to be annoying. I will try putting the metal sump on a rubber pad to try to reduce this.
    Any other thoughts or recommendations would be appreciated.
Working...
