Piezoelectrically driven micromembrane pumps are the beating heart of microdispensing systems. The Fraunhofer EMFT team has extensive knowledge and practical experience in the design of piezo micropumps. On this basis, the technological parameters in terms of dosing accuracy, backpressure rigidity, size, energy consumption, particle resistance, bubble tolerance and "free flow" protection can be adapted to the specific requirements of the application.
