The BP7 micropump is a robust and reliable solution for microfluidic systems. Each pump undergoes rigorous testing and quality control before it leaves our factory, ensuring it meets the highest standards.

With its low maintenance requirements, you can integrate it seamlessly and immediately focus on building your system without worrying about failures or weak points.

Depend on our proven micropump technology for your needs.

Cost-efficient production

Our micropumps combine cost efficiency with high-quality performance. Made almost entirely from durable PPSU plastic, they enable high-volume production at reduced costs without sacrificing reliability.

Thanks to their space- and energy-saving design, these micropumps are a smart and affordable choice for industries demanding both advanced functionality and cost savings.

Versatile and durable, they set a new standard for affordability.

How our micropump is assembled

The micropumps in Bartels’ BP7 series are compact and robust double diaphragm pumps.

At their core, they operate with two piezo actuators, which drive the diaphragms to enable fluid movement. These actuators are electrically connected via a flexible cable, ensuring efficient energy transfer.

All components are housed in a sturdy, space-saving casing, providing durability and ease of integration into various systems.

Functional principle: How piezo electric micropumps work

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: Discover the possibilities of our micropump

Even in the most demanding applications, our BP7 micropumps prove their versatility.

Whether in:

medical technology
analytical technology
mechanical engineering
space research
many other applications

– our micropumps set new standards.

Our BP7 micropumps are truly tiny, but they have what it takes. With extremely small dimensions and low weight, they are already equipped for many fields of application. But that is not all. These little powerhouses offer an impressive particle tolerance of up to 40 µm and are extremely temperature-resistant. This makes them a real all-rounder for a wide variety of applications. Variable flow rate adjustment guarantees a wide range of possible applications.
