The functional principle is based on a piezoelectric diaphragm in combination with passive check valves. A piezo ceramic mounted on a coated brass membrane is deformed when voltage is applied. By the resulting downstroke, the medium is being displaced out of the pump chamber below. The check valves on both sides of the pump chamber define the flow direction. When the voltage decreases, the piezo's corresponding deformation causes an upstroke of the membrane. The medium is sucked in and the chamber is filled again. In every second, the pump can do several hundred pumping cycles. The pumping performance can be influenced by adjusting the parameters. For air & gas applications, the mp6-gas is available.


This radically simple pump design allows for easy adaptation to specific flow rates or backpressure. Various types of test equipment are available for purchase to assist you in controlling your micropump.

Cost-effective, reliable with long life, and easy to use, these micropumps can transform your product. Take a look at the many application notes listed below to learn more.
