Bartels - Model mp6-liq -Micropumps
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.
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.
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.
The mp6 micropump is robust and reliable. Quality is our top priority. We test every single pump before we send it to you, so you can start building your own microfluidic system right away.
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!
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.
Our micropumps can be used in many different ways in medical and analytical technology, mechanical engineering, space research and many other applications.
