To achieve individual flow rates and optimal flow conditions, the driving parameters need to be tested,
optimized and confirmed by testing under full application conditions. As an example, typical driving
parameters are listed below to give a general orientation for testing. The parameters have been obtained
using the mp-x controller with the SRS signal preset. Please refer to chapter 5 for operation of the mp-x
controller.
Target flow rate Amplitude Frequency Target flow rate Amplitude Frequency
7 ml/min 250 V 100-110 Hz
2 ml/min 220-240 V 20 Hz
6 ml/min 250 V 80-9 0Hz 1 ml/min 125-135 V 20 Hz
5 ml/min 250 V 55-65 Hz 0,5 ml/min 90-100 V 15 Hz
4 ml/min 250 V 40-50 Hz 0,25 ml/min 85-95 V 8 Hz
3 ml/min 250 V 30-35 Hz 0,1 ml/min 80-90 V 3 Hz
As a general guideline the amplitude should be kept as high as possible while varying the frequency.
4.3.1.2 Medium: air
Driving the micropump with the controller mp-x at 300 Hz with 250 V, flow rates of 18 ml/min and
backpressures of up to 100 mbar have been achieved.
In general, for driving the pump with air, higher frequencies should be used than for water. To minimize
audible noise, using the sine signal is recommended. As this is preliminary data, please contact us for more
information when you intend to use the pump with air.

4.3.2.1 Medium: Dl water
The flow curves present typical flow data, results may differ under varying operation conditions.
