Thompson Pump kicked off the 2017 CONEXPO-CON/AGG unveiling its concept “Pump of the Future”.
What’s so unique about this concept pump? The answer is in what you hear; or more specifically, what you don’t hear. Typical operating noise from diesel-driven pumps is excessive and undesirable — and in some cases can even cause permanent hearing damage to workers at or near job sites where pumps are being utilized.
Enter Thompson Pump’s Active Noise Cancellation system (ANC). It mitigates unwanted sound from diesel-driven pumps through the addition of a secondary sound (anti-sound) that is designed specifically to cancel out the primary one.
“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,” said Dale Conway, Vice President of Engineering for Thompson Pump. “Better still, the ANC system is completely standalone and automated – and it requires absolutely no user intervention.”
