Abstract The structure and the operating principle of micro valveless pump are investigated theoretically and by experim ents．The m athem atical m odel of pressure and flow rate within the micro nozzle/diffuser is established to analyze the effects of nozzle/diffuser parameters on output flow rate of the micro valveless pump． The effects of the structural parameter and driving condition on the operation performance of the pum p are discussed in details． The work provides therefore useful reference for structure optimization as well as the driving diaphragm selection of micro valveless pump．
