This ultrasonic, pneumatic piezoelectric micropump delivers strong performance in applications where optimum control of small volumes is critical.

Applications include micro-fluidics, pipetting, wearable devices and portable sensing technologies across the medical, life science and environmental monitoring industries.

The key features of this disc pump all contribute to a design resulting in ultrafast, millisecond response time, silent, vibration operation (?10dB), and high-precision controllability ?0.1 perent, true pulsation free flow, in a lightweight (5g) compact package (29mm diameter).

While not designed to flow liquids directly, it’s infinite turn-down ratio and pulsation-free flow performance enables users to control liquids indirectly via an air-over liquid method.

Furthermore, as a disc pump, it allows users to generate and control a head pressure (air) with high resolution, resulting in optimum precision liquid dispensing or displacement (lab-on-a-chip).

Specific applications include pick-and-place robotics, patient simulators, compression therapy, blood pressure monitoring, and time-metered dosing.

Every pump is 100 percent functionally tested for performance and designed using materials that ensure consistent long-term performance.
