Technical focus: Disc Pump "how it works"

In this post, we take a look at the operating principle behind Disc Pump, which exploits recent advances in non-linear acoustics.

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. By instead creating a standing wave we are able to deliver much greater pressures and flow than traditional piezo pumps – and because our pumps operate at ultrasonic frequency they are completely silent. Turning an ultrasonic standing wave into useful pumped flow requires a highly specialised valve, able to respond in a matter of microseconds. Our patent-protected designs do exactly this, delivering unrivalled pneumatic performance.

We've recently completed a short animation on the operating principle of the pump. Watch it below.
