A bout Bartels micropumps

Micropumps transporting the tiniest amounts of gases or liquids can be considered the heart of microfluidics. In many sectors they have become indispensable.

Applications

Our 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, our 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, our micropumps can be manufactured cost-effectively in high volumes. The material is either PPSU or PP. Therefore, it is a real cost wonder!

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.

Micropumps mp6

The micropumps in Bartels’ mp6 series are miniaturized double diaphragm pumps. Each micropump is run by two piezo actuators. Due to the space- and energy-saving construction they are cost-effective even in high quantities. The materials used make the micropumps remarkably versatile. Variable flow rate adjustment guarantees a wide range of possible applications.

The mp6-liq micropumps can be used to promote both liquids and gases, for liquids in particular the mp6-pp and mp6-pi offer a wide range of usable liquids, while the mp6-gas and mp6-gas+ are specialists for gas promotion. To say is that all of our mp6 micropumps are able to promote liquids, mixtures and gases.

One rule applies to all micropumps in the premises:

The flow rate of the micropumps shows a linear dependency on the back pressure.
At 0 mbar back pressure the maximum flow rate can be achieved and at the maximum back pressure the flow rate is decreased to 0 ml/min. The relation of pressure and flow rate is linear.

mpSmart - microfluidic systems

Miniaturization and functional integration continue to be important trends in the areas of Life Science, Medicine, Pharmaceuticals and Diagnostics. As part of this, microfluidic components and systems are a fundamental element in the development of innovative solutions. However, microfluidics and microsystem technology are used by manufacturers in other sectors as well, such as the automation, aerospace and energy sectors, where they increase the efficiency of products and processes by using ever smaller intelligent systems.

We have developed the mpSmart system to meet these requirements. The system is based on our mp6 series of micropumps. mpSmart means that the micropump is being combined with one or more additional components, such as a sensor, a microfluidic chip or an active valve. This turns it into a microfluidic system with additional functionality. One feature of the intelligent mpSmart system is that our experienced developers select and fully pre-assemble the individual components with all the right settings for your purposes, so that the system is ready for operation. The electronics and the control systems are precisely matched to each unit. Of course to help you with this, we will also provide you with some individual software that has a user interface you will find simple and intuitive to operate.

The family already includes the mpSmart-Dosing, the mpSmart-Lowdosing and the mpSmart-Flowstop. The mpSmart-Dosing and the -Lowdosing are small but intelligent dosing systems with sensors that allow flow rates to be set with the highest level of precision for different fluids – whatever the temperature or viscosity. With the mpSmart-Flowstop, the micropump is connected to an active valve instead of a sensor, so that the microfluidic system can be switched as needed.

mpSmart-Flowstop

But of course with the mpSmart system there are any number of other potential configurations imaginable using commercially available components. With new applications the sky’s the limit. Our experts from the field of micro engineering will be pleased to help you turn your innovative ideas into a marketable solution!
