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.
TTP Ventus won Business Weekly’s Disruptive Innovation award in 2018, recognising our disruption of the micropump industry and the product innovation that Disc Pump™ enables.
