Requirements for successful cooling water pumping—lessons learned from a major failure

Noise and vibration were so unmanageable that the pumps could not run even for a short period anywhere near their rated capacity. A crash remedial project was launched, which included lowering the base of all the pumps, motors and turbine; modification of pump impellers and piping (54 in./42 in.); and procurement of pipes and fittings, all at enormous cost and production loss.
