The new noise cancellation technology can be fitted to any Thompson pump

8597 Thompson Pump revealed a new noise cancellation concept it calls 'Pump of the Future' at CONEXPO-CON/AGG.

The company's Active Noise Cancellation (ANC) system mitigates unwanted sound from diesel-driven pumps by adding a secondary sound that acts to cancel the primary noise.

“When you create a secondary sound wave - with the same amplitude that has an inverted phase to the original sound - the waves combine, form a new wave, and effectively cancel each other out,” says Dale Conway, vice president of engineering for Thompson Pump. The ANC system is standalone and automated and requires no user intervention once it is set up.

A Thompson pump fitted with ANC can be housed in the company's Silent Knight sound-attenuated canopy enclosure to further reduce noise levels.

Silent Knight lowers pump noise levels by 20+ dBA to just 68 decibels or less from 7 metres and encloses the entire pump in a lockable case. The canopy is available on nearly every Thompson Pump model and can be added to existing models in the field for convenience.

Thompson Pump demonstrated the ANC system fitted to its 4JSCM-DYST-3TNV solids handling compressor-assisted pump in the Silent Knight canopy at CONEXPO-CON/AGG.
