Driving the Micro Pump mp6

The micropump mp6 can be driven by alternating, (a) voltages at a maximum amplitude of 250 V, and (b) frequencies between 0 and 300 Hz. The voltage determines the deflection height of the piezo actuator and the frequency the number of the deflections. By varying these parameters together with the signal shape (rectangular, sine, SRS), different flow rates can be achieved. A rectangular signal gives highest fluidic flow rate, while a sine wave minimizes the audible noise. The SRS wave is typically the optimal setting for aqueous solutions. The evaluation controllers, mp-x, mp6-OEM and mp6-EVA, enable the customer to test the micropump and develop optimal drive conditions for specific applications.
