Microdiaphragm pumps require compact drives that can provide a continuous flow and variable flow rates. Due to the small volumes per pumping cycle, high cycle rates up to the kHz-range are necessary to achieve high flow rates.
A microdiaphragm pump comprises a valve unit and the pump diaphragm, which in conjunction with the piezoelectric actuator forms the pump drive.
The dispensing quantities range from milliliter, microliter, nanoliter right down to the picoliter range.
The fields of application for piezoelectric micropumps are in laboratory technology, medical technology, biotechnology, chemical analytics, and process technology, which require reliable metering of minute amounts of liquids and gases.
