This sound attenuated canopy reduces pump noise levels to or below 69 dBA.
In the late 1990s, an increase in urbanization and infrastructure development led to a rise in residential, public and commercial construction projects. With more of these projects taking place in densely populated areas, construction noise in neighborhoods became a big issue, facilitating the need for quieter equipment.
One such project was the expansion of the University of Central Florida campus with the development of Research Park and Greek Park. Contractors called on Thompson Pump to provide pumping equipment to dewater the construction sites but wanted the equipment to minimize noise due to its proximity to neighborhoods and businesses. Thompson Pump quickly began designing and building a prototype unit to be tested on the jobsite. The unit was a six-inch portable diesel driven pump with a metal enclosure containing sound absorbing material that covered the pump and engine for noise abatement, affectionately nicknamed “Silent Knight”. With the prototype, Thompson Pump engineers achieved an overall noise level 10-15 decibels lower than the non-sound attenuated version.
The Silent Knight became an instant success. The line has since been expanded to include various types of pumps, sizes and power sources. Today, almost 50% of Thompson Pump’s production includes sound attenuated pumps.
