Reducing pump noise in cooling tower applications

Cooling tower applications are one of the areas where excessively noisy pumps are most frequently encountered. High noise levels are not only a nuisance but also a potential indicator of diminished pump performance. Steve Schmitz , senior product line manager for centrifugal pumps at ITT's Fluid Handling Division, provides practical tips for identifying the causes of excessive noise and for reducing or eliminating it, thereby improving operating costs.
