Piezoelectric Pump for pumping liquids Applications • For supply and drainage • For cooling circulation • For medical injection • For liquid sampling FlowRate Discharge Pressure (mL/min) (kPa) The performance data is measured at the rated conditions. 1)The reference data is based on water at 25 degrees Celsius with unloaded condition. 2)The ambient operating temperature range is from 5 to 50 degrees Celsius, the ambient liquid temperature range is from 5 to 50 degrees Celsius (non-freezing), and the ambient operating humidity range is from 35 to 85% (non-condensing). When the liquid temperature is low, the valve will be hardened. As a result, the flow rate will be decreased. This could be applied for liquids with high viscosity. The materials that will be under influence of the applied liquids are the housing, liquid contact sheets, valves, and O-rings. Please confirm the suitability under any applied conditions. Any minute quantities of additives and composite materials found in certain liquids may influence the performance of the unit several months later. 3)You may use the product at low voltage, but it will result in lower outlet pressure. 4)Performance may be compromised by restrictive tubing/piping or mounting position of the pump in the application. 5)The above performance data is measured at the rated condition as we described. Note: The Bimor does not fulfill explosion-proof construction in any applications. Please install isolating transformers or similar protective devices on the wiring for your safety.

Compact, lightweight, durable & quiet As the Bimorph also acts as a diaphragm it has no motors or shafts or other troublesome mechanisms, and thus minimal vibrations and fewer breakdowns. The Bimor is lighter, quieter and more durable than traditional pumps. We have achieved maintenance free continuous operation for 60 months. Low power consumption & electromagnetic noise The Bimor is driven by low energy consuming piezoelectric elements. Consequently it costs very little to run and emits virtually no electromagnetic noise. Simple flow rate adjustment As the flow rate of the Bimor is proportional...

The Next Step in Pump Miniaturization Revolutionary piezoelectric bimorph technology The Bimor's driving force, the bimorph, comprises two parallel piezoelectric wafers. Their nature is to expand or contract depending on the direction of the voltage. Therefore when an alternating current is applied, one wafer expands then contracts while the other contracts then expands, causing the bimorph to bend. Repeating the cycle creates the pumping action.
