They are very small, they are very flat, made of plastic. And they offer defined premium quality for countless applications - from the deep sea to space: our micro-pumps.



Spray generation

Thanks to the combination of our pumps with different spray technologies, we can atomise numerous fluids - down to almost molecular size.

Originally, we used the necessary micro-pump to atomise active ingredients and fragrances.

Of course, the working principle also works in countless other areas. You can also atomise drugs in this way.


The variety of applications is literally limitless.

We often go beyond traditional procedures (such as elastomer drug dosing pumps), which are being redefined with our pumps to extend the traditional capabilities of portable drug delivery systems.


In microfluidic systems, among others, the novel method of electrowetting is used where the surface tension of fluid beads is deformed by applying an electric field.

As a result, a drop of fluid can even move. This method, developed as part of a cell sorting project, offers the practical ability to control fluids and can therefore be considered a key technology for future microfluidic diagnostic systems.


Systems, for which our micro-pump systems are predestined, where development, customisation and ultimately the solutions are fundamental to every Bartels project. This means that: The development of solutions for microfluidic applications is the core issue in our microEngineering.

Drug dosing


Dosing fluid drugs in a defined time and amount can be done either as stationary or with the help of transportable solutions.


In combination with a sensor even in mobile infusion our micro-pumps ensure a precise dosing that is absolutely reliable over a long period of time.


For this we test every single pump in the entire production process and can thus guarantee the quality level of our products at the highest level.

Sleep apnea

 Sleep apnea syndrome (sleep apnea for short) is the result of regular respiratory disorders and/or less ventilation of the lungs during sleep.


Micro-pumps are also used in the conservative treatment of sleep apnea patients in CPAP (Continuous Positive Airway Pressure) respiratory therapy devices.

These devices have a blower that is connected via a hose to an nCPAP mask.

With the help of these masks, the micro-pump generates a slight overpressure of 5 to 20 millibar during sleep in the respiratory tract.

This pressure prevents the collapse of the respiratory tract and thus the apnea.

Tissue Engineering

The Tissue Engineering concerns the artificial production of biological tissues through the targeted cultivation of cells.


A fascinating topic in medical technology.

Cartilage or other damaged structures can already be cultivated.


Researchers assumes that in the future entire organs could be grown in this way.


Our micro-pump is used, for example, in bioreactors during the growth of the cells in order to supply the growing tissue parts with nutrient fluids.

Wetting of grafts

Grafts are transported from the donor to the recipient in special boxes.


During transport, the grafts must be permanently moistened.

Here, too, the micro-pump is used.





In medical diagnostics, the transport of fluid substances such as blood, urine, saliva - plus the reagents necessary for the test - is important in order to carry out initial rapid tests or more in-depth examinations in hospitals and laboratories.


Here, too, our micro-pumps display their advantages thanks to their small size and sometimes significantly accelerate the analysis, while at the same time delivering reliable results and impress with short lead times.


These can be life-sustaining aspects when it comes to assessing a patient's condition as quickly as possible in order to be able to make diagnostic decisions.

Space travel


Space missions are extremely expensive high-tech projects where the technology has to ensure maximum reliability.

If a component fails in space, tens of millions are lost, sometimes this is in the billions.


Also for this reason, the student small satellite group of the University of Stuttgart e.V. (KSat) has worked on a practice project with a maintenance-friendly Bartel pump, which operates without mechanical parts: the mp6.

This micro-pump will now make its way to the ISS where it will pump a ferrofluidic fluid to test a NASA experiment for an alternative rocket propulsion in weightlessness.


Bartels goes Orbit.

Sensor feeding

It is not only the small dimensions which make it possible to operate our micro-pumps as a unit with the sensor as integrated assemblies.


Our pumps also consume very little power, enabling a trouble-free battery operation in order to operate small, mobile devices.

Depending on customer requirements, we can either integrate the electronics into the system electronics or install them in an enlarged pump housing.


Therefore, the areas of application of this "Supply" of the sensor ranges from the Blood glucose measurement via the blood pressure measurement, the blood oxygen saturation to the monitoring and control of anaesthetic gases.



Sensor technology (CO2, humidity, detection of carbon monoxide, explosives)

Processes in the industry must become ever safer and more efficient.

Sensors play an important role in this.


To obtain stable and unambiguous readings, the sensor must be reliably supplied with the analysis fluid.

A technical challenge that our micro-pump can easily ensure. This allows the system to react more quickly to fluctuations in the measured value and/or to compensate for changing concentrations, such as can occur, for example, in the case of catalytic gas sensors.

On the other hand, since many sensors only function insufficiently in the event of a passive flow, our micro-pumps can open up new fields of application here and sometimes even save lives not only in the detection.

Water Sampling

In many places, the quality of water must be checked for Legionella, lead, heavy metals, medicines or pesticides.


In the house, in swimming pools and much more.

The necessary samples can be easily and conveniently made with the help of our micro-pump.


If the subsequent analysis determines that certain substances have to be added to the water again, this can be done with a second pump in the amount determined in the course of the procedure.



Microdosing: fragrance dispensing

Lifestyle is not a trend, but an all-encompassing attitude to life.

We have only limited influence on whether world around us smells good, but we can influence the olfactory atmosphere in our own homes, in the car, at work, etc.

But even in public buildings and rooms, odours can be adjusted between neutralisation and refreshment.


Modern room scenting systems can use micro-pumps to disperse a defined fragrance over a long period of time without using individual fragrances more quickly than others, because the precise liquid transports guarantee the correct mixing ratios of the fragrance at any given moment. That is why, moreover, that the fragrance remains unchanged during operation.


In all cases, our micro-pumps, equipped with a sensor, can precisely dose the liquids to be atomised in order to pamper the environment with a very personal scent.

Smoke Generator: E-cigarettes

E-cigarettes are the most recent smoker trend and at the same time a booming industry between the production of the e-cigarette itself and the countless liquids.


To transport these from the tank to the evaporator, micro-pumps can transport the fluids. In some systems, the filling of the reservoir of the e-cigarette is done by means of the micro-pump.


Basically, many types of fragrance are used in e-cigarettes which - chemically speaking - can be quite aggressive and require the material properties of the e-cigarette.


Since our micro-pumps are made of a material-resistant plastic and, moreover, work with special films, they cannot be harmed even through aggressive fluids which also include the liquids.

Microdosing: coffee machine

In ever smaller automatic coffee machines the micro-dosage of complementary flavours with the help of our micro-pumps can create first-class coffee specialities.


Vanilla, Caramel, Amarena ... as always: The dose determines the quality.


So the flavour additives must be put in a nutshell so that a first-class coffee becomes an outstanding speciality.
