Revolutionary, quiet pump technology
No motors, gears, shafts or bearings—ensures a long operating life
Driven by two low energy consuming piezoelectric elements
Applications include: gas sampling, chemical transfer and sample-cooling

The low energy consuming piezoelectric elements within the pump expand or contract depending upon the direction of the voltage. When an alternating current is applied, one wafer expands then contracts while the other contracts then expands, causing the two elements to bend. As this cycle repeats, it generates a pumping action. The pump will pump either liquids or gases.
