Abstract：In order to explore influence of initial volume of the pumping chamber on performance of a piezoelectric pump, several piezoelectric pumps with parallel doublechamber and a checkvalve were manufactured, in which six different initial volumes were designed. The performance of those pumps was measured under different compression ratios (the ratio of stroke volume over the initial volume) when they were driven by a bimorph actuator at the 110 V driving voltage and frequency of less than 400 Hz, in the cases that water and air were handled, respectively. The results showed that a pump has the best output flow rate when its compression ratio was 1/18 for water, and the highest flow rate as high as 1 330 mL/min.A larger compression ratio could result into a higher output pressure and a better selfpriming capability.The maximum output pressure and the highest selfpriming water column height were 58.5 kPa and 69 cm, respectively. For air, however, the larger the compression ratio, the better the pump output performance. The maximum output flow rate and the highest output pressure were 850 mL/min and 6.5 kPa, respectively. When the compression ratio was less than 1/32, the pump performance would be breakdown.
