Bartels

For more than 20 years Bartels Mikrotechnik has been a pioneer in the manufacture of microsystem components. The company specializes in innovative applications of microsystems technology (MST) in the branches of classical consumer goods, mechanical engineering and medical technology.

Piezoelectric diaphragm micropumps made by Bartels Mikrotechnik transport the tiniest number of gases or liquids in a wide variety of applications including medical drug delivery, fuel cells, mobile applications, consumer, cell culturing and much more.

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.

Functional Principle

The functional principle of Bartels micropumps 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 down stroke, 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.

Applications

These micropumps can be used in many different ways in medical and analytical technology, mechanical engineering, space research and many other applications.

Small, lightweight, robust and reliable

With their small dimensions and low weight, Bartels’ micropumps are already equipped for many fields. Added to this is particle tolerance down to a particle size of 40 µm and good temperature resistance. Together, the micropump is a small miracle of use for the most diverse applications.

Cost Effective

Produced almost entirely from plastic, these micropumps can be manufactured cost-effectively in high volumes. The material is either PPSU or PP. Therefore, it is a real cost wonder!
