Acoustical Products Made in USA.
Municipal water treatment plants and pumping stations rely on large industrial pumps to move water through filtration systems, treatment processes, and distribution pipelines. These pumps operate continuously to maintain consistent water pressure and supply across entire municipal infrastructure networks. During operation, large pump systems often generate sound levels between 85–95 dB, particularly when several pumps operate simultaneously within the same facility.
Pump noise is typically generated by multiple sources within the system. Electric drive motors produce rotational vibration, while hydraulic forces created by high-pressure water movement generate additional acoustic energy. Water traveling through large pipelines and valves can also create turbulence noise that contributes to the overall sound levels within the pump station. These combined mechanical and hydraulic forces create a constant background noise that can spread throughout the facility.
Because pump stations operate around the clock, maintenance crews working inside these facilities may experience continuous exposure to elevated sound levels during their shifts. Workers responsible for monitoring pump performance, inspecting mechanical components, and performing maintenance tasks must often communicate in an environment dominated by mechanical noise. In some cases, pump noise can even travel through building structures and spread into nearby offices or control rooms.
Installing pump acoustic enclosures is one of the most effective solutions for controlling this type of equipment noise. Silencor® Metal Enclosures Systems function as industrial machinery soundproof housings and metal equipment sound enclosures that isolate pumps within structural acoustic containment systems. These heavy-duty acoustic steel enclosures surround pump equipment with sound-absorbing panels designed to block and dissipate sound waves.
When pumps are enclosed within industrial noise reduction enclosures, facilities can achieve 20–25 dB of sound reduction, lowering a typical 92 dB pump station environment to approximately 67–72 dB in surrounding areas. These modular acoustic metal enclosures also include removable access panels and ventilation systems, ensuring technicians can safely maintain equipment while maintaining effective acoustic containment.
