When water districts began changing pumping equipment, replacing submersibile pumps with vertical pumps, they discovered a significant increase in the noise radiated by their equipment. This paper describes and discusses an enclosure that reduces the radiated noise and provides ducted air in and out for cooling the electrical drive motor. Data will be presented showing the noise levels before and after installation of the enclosure both near and at several distances from the pump. In addition to noise reduction the enclosure results in cooler operating temperatures which in turn aids in extending the service life of the pumping equipment.
