Circulation Water Pumps Exceed ANSI HI 9.6.4 Vibration Limit

The vibration gradually increased within a year from just below the 0.17 in/s RMS ANSI/HI 9.6.4 vibration limit upon installation to almost 1.0 in/s RMS when MSI arrived. Based on MSI's testing, one pump's "trunion" mode is being excited in the parallel direction, while the mode on the sister pump is in the perpendicular direction.
