Abstract—Piezoelectric pumps possess many advantages such
as quiet operation, quick response, simple structure, and
nonelectromagnetic radiation. This paper presents a PZT
( Lead zirconate titanate ) liquid pump with low power, high
flow rate, small size, and light weight. The liquid pump is
composed of the piezoelectric ceramic, elastomer valve, and
PET ( Polyethylene terephthalate ) pump body. The power
consumption, flow rate, body size and weight of the pump are 1
W, 800 ± 5% ml min-1, 50 × 50 × 10 mm., and 50 g, respectively.
Additionly, the pump works at an exciting voltage of 50 Hz, 40
V. According to the applied voltage or frequency to a PZT
pump, the flow rate of the fluid is able to be controled. Besides,
the liquid pump is suitable for various fluids such as water,
alcohol, soda, hydrochloric acid, etc.
Index Terms—Piezoelectric, pump, ceramic, liquid, PZT.
