Disc Pump - How it Works animation
In this animation, we take a look at how Disc Pump exploits recent advances in non-linear acoustics to create a silent,high-performance micropump.
Most piezoelectric gas pumps rely on the movement of a piezo actuator to compress the gas in a cavity, thereby increasing its pressure. Such ‘displacement’ pumps have limited performance because the movement of piezo actuators is very small.
In contrast, Disc Pump does not rely on compression. Instead, it creates a high frequency, high amplitude standing wave and then rectifies that wave with an ultra-fast valve. This principle enables Disc pump to generate much greater flows and pressures than traditional piezo pumps – and because Disc Pump operates at an ultrasonic frequency, it is completely silent.
