The 2x 4x and 6x peaks prevailed in the pump bearings. Higher multiples of running speed occurred on the pump from 40 to 100 kcpm particularly during the vertical misalignment runs. The twice fourth and eighth running speed frequencies are a result of the S-shaped grid as it traverses from its maximum tilted and pivoted positions twice each revolution on both the coupling hubs. The third and sixth running speed multiples occur as the metal grid in the coupling changes its position during each revolution of the shafts.
