Abstract：In order to research structure effect on output performance of piezoelectric pump with two chambers in series, two structural forms of piezoelectric pump with two chambers in series with a diversion and no diversion slot were designed according to its working principle. The experimental samplers were manufactured and output performance experiments were carried out with water and air as the medium, respectively. The experimental results show that output flow rate of piezoelectric pump with two chambers in series with a diversion slot is better by powered 110 V sinusoidal AC drive voltage. The maximum output of liquid and gas flow rate are 1 100 mL／min and 650 mL／min, respectively, but residual bubble in the diversion slot is its disadvantage. Both the overall output pressure are closer and maximum output pressure reaches to 100 kPa. The self-priming performance of pump with no diversion slot is better and the largest self-priming water column height is 45 cm.
