Flexshield installed acoustic pump covers on two large electrical pump motors at a public utility water plant in Perth, Western Australia.
The client required noise control treatment for two large electrical motors driving the pumps as the noise levels generated did not comply with workplace health and safety guidelines.
Key project challenges included providing penetrations to accommodate the numerous electrical, water and air feeds without compromising on the effectiveness of noise control. The emergency stop button could not be inside the acoustic enclosure. Additionally, the enclosure had to be easily removed for regular maintenance.
Flexshield designed, manufactured and installed two individual acoustic pump covers using Sonic System V50 acoustic panels for the roof and Sonic Curtain as the flexible sides of the noise control enclosures.
Complete access on demand was facilitated using Sonic Curtain with Velcro slits and side joiners. Penetrations were formed in-house at the manufacturing stage for quick and simple installation.
While the Sonic System V50 acoustic panels have ensured a reduction of Rw 31dB in noise levels, the Sonic Curtain has reduced noise by Rw 27dB.
Flexshield manufactures a complete range of noise control solutions.
