View Piezoelectric Micro Pump - Built-In Driver-Type Drawing PDF A piezoelectric element drives this miniature diaphragm pump, and its driver board is built-in into the pump. It enables the pump to deliver a constant flow rate by operating the pump with constant voltage and constant frequency signal generated by a direct current voltage supply. The pump can be used or stopped by inputting an electrical signal into the pump control signal lines.
