Abstract To explore effects of number of chambers on performance of piezoelectric pump, a new structure, e.g. serial-three-chamber piezoelectric pump was designed and fabricated by using three passive check valves based on the working principle of piezoelectric pump with more chambers. A series of experiments were performed on the pump with water under different working conditions and the experimental results were compared with those of a serial-double-chamber piezoelectric pump. The best working condition was studied analytically and validated experimentally for the designed pump. It was turned out that the flow rate of the three-chamber pump was lower than that of the double-chamber one, the flow rate of the former was 0.7 times the latter, but the output pressure of the former was as high as appro-ximate 1.5 times that of the latter. This suggests that increasing number of chambers can improve the output pressure, while it can reduce output flow rate as well. For the designed pump, the 860 mL/min maximal output flow rate and 80 kPa output pressure can be achieved under the 110 V AC driving voltage.
