Design and Performance of Piezopumps Craig E. Nelson - Consultant Engineer
Typical Commercial Piezo Pump 1 • Maximum pressure available seems to be on the order of about 12 PSI • Flow rate at a pressure of 1 PSI seems to be about 5ml/min for 1 inch dia. piezos • Pumping rates for liquid seem to be about 3.5 that for gas at 1 PSI back pressure
About 5 PSI Piezo Pump Performance Capability Typical Commercial Piezo Pump 2
(100 hecto Pascals = 1.45 PSI) 11.6 PSI Typical Commercial Piezo Pump 3
Typical Commercial Piezo Pump 4 (100 hecto Pascals = 1.45 PSI) About 1 PSI 5.8 PSI 2.2 PSI
Piezo Pump Elements Typical Piezo Pump Assembly Disc Type Valve
Typical Piezo Disks 15, 27 and 35 mm Piezo Disks
Summary The performance of several commercially available piezopumps has been presented. Some aspects of the design and construction of typical piezopumps were shown.
