Electrical Input: amplitude of 250 Vpp and SRS-Signal with 100 Hz (for liquids) and 300 Hz (for gases)
Measurements with sensors:
volume flow
range: 0 - 10 ml/min
accuracy: +/- 1% FS (=0.1 ml/min)
pressure
range: 0 –1 bar
accuracy: +/- 0.35% (= 3.5 mbar)
Other application specific outgoing inspections can be offered for all pumps upon customer demand.
In order to guarantee proper function of the delivered goods and exclude transportation damages please check the
incoming devices according to specifications after receipt.
Based on these results a replacement can be carried out within 14 days after delivery free of costs.
Operating the micropump
In this chapter the operation of the micropump during the evaluation is described. This chapter provides information
on the proper connection of the pump with tubing and electrical cables and typical driving parameters to start the
evaluation.
Please connect suitable tubes to the inlet and outlet. The tubing should have an inner diameter of ~1.3 mm for the
mp6, mp6-AIR, mp6-AIR-HP and mp6-pi and ~1.2 mm for the mp6-pp. The micropump has to be connected to a
suitable controller as described in the next sections.
The electrical connection of the micropumps flexible connector is described in the corresponding chapter. The flexible
connector will be attached to the desired controller.
On both type pumps, traces of surface corrosion may appear on the electrical connector. This corrosion only causes
a visual influence, negative effects on the pump performance could not be detected based on performance tests

carried out by Bartels Mikrotechnik. Because of the mechanical fixation inside the electrical connector and due to
the use of elevated driving voltages it is ensured that the pump performance is not affected by the surface corrosion.
In a long term, we will work on improving the production process. Until then, referring to the unrestricted pump
performance we ask our customers to excuse visible defects on the electrical connector.
In general, the micropump can be driven with positive alternating voltages with maximum amplitude of 250 V
at a frequency between 0 and 300 Hz. A rectangular signal results in best fluidic performance while a sine wave
minimizes the audible noise. The actuators must be driven with a 180° phase shift in the signal.
If a pump will be damaged while using a customer’s controller, we do not provide any warranty. We recommend
using our dedicated controllers.
DANGER
THE MP6-SERIES MICROPUMPS ARE OPERATED AT HIGH VOLTAGES. BEFORE
OPERATION, MAKE SURE THAT ALL SPECIFIC REGULATIONS FOR ELECTICAL SAFETY
ARE FULLFILLED.
Connecting the mp6-series to the cable
The pumps can be connected via a FCC connector. The layout of the connector and pin assignment of the pumps is
as shown below. Each piezo (P1 / P2) has a single lead for the negative (-P1/-P2) and the positive (+P1/+P2) supply
voltage.
The recommended connector is a 4-pin 1.25 mm pitch FCC connector manufactured by Molex. The straight
version part number 39 53 2045. An alternative is the angulated version with the part number 39 53 2044.
The connector is available in different versions to fit various applications. Reference drawings and further
specifications are available under www.molex.com .
The recommended maximum wire length between controller and the pump is 1 m. The customer has to assure that
the assembly of pump, controller and electrical connection complies with the EMC regulations and electrical safety
in the specific field of application.
To connect the pumps and Molex, refer to following three figures. Orientate both components as indicated on the
first picture, the pumps facing downwards with its serial number marking (!) and the Molex connector with the four
small openings visible from above. Then insert the mp6/mp6-pp flex into the Molex connector (Step1). Close the
Molex connector to complete the interconnection between both components (Step 2).

Rev. 3.1 (08.2020)
1 Änderungen vorbehalten
If the pump should be removed again, the Molex connector needs to be opened before removal!
In order to prevent damage to the flexible cable, the following points should be considered for the final pump
assembly:
-the flexible connector must not be bent around sharp edges or kinked
-the flexible connector must not be bend on top or bottom of the pump
-the Molex connector is not water tight, additional sealing with e.g. silicone will be necessary
-fixation of the Molex connector in the final assembly is recommended
The Molex flex cable has contacts only on one side, so it can be connected to the Molex connector only in one way.
If connected in the other way, the pump will not function.
Cleaning the system
The pump can be washed with water, alcohol (isopropanol) or if necessary with weak acid by pumping or by flushing
with the help of a syringe. Flushing is only possible in pump direction!

Rev. 3.1 (08.2020)
Typical operation parameters
mp6-hyb and mp6-pi
The description here applies to the medium water. For the delivery of gases, please read the section to mp6-gas.
Please note that the regular mp6-hyb, as well as the mp6-liq can also pump gases, but has not been specially
measured for this purpose.
To achieve individual flow rates and optimal flow conditions, the driving parameters need to be tested, optimized and
confirmed by testing under full application conditions. The typical flow rates given by us have been determined using
an mp-x controller with SRS wave form. Please refer to the corresponding manual for operation of the mp-x
controller.
If lower flow rates are required, it is advisable to use a restrictor for throttling and to operate the pump at the
recommended parameters.
As a general experimental approach, we recommend a high amplitude at varying frequencies. The performance
depends on the environmental conditions.
mp6-gas
Driving the micropump with the controller mp-x at 300 Hz with 250 V, flow rates of typ. min. 20 ml/min and
backpressures of typ. min. 100 mbar can be achieved.
In general, for driving the pump with air the following points should be taken into account:
-Higher frequencies should be used (compared to pumping water).
-Large amplitudes respectively driving voltages should be used.
With low frequencies and amplitudes, the volume flow and pressure generation is rather weak due to the passive
character of the valves inside the micropump. These valves are more effective with fast and high pressure changes
induced by the actuator.
If the desired flow rates should be small, the application of a restrictor is recommended. Please contact us about the
right choice of the restrictor!
Please note the different frequency ranges of the control units.
To minimize audible noise, using the sine signal is recommended.
The signal has influence on volume flow and back pressure, thereby applies rectangular > SRS > sine.
mp6-pp
Again the following applies to the media water. Note that the mp6-pp can pump gases too, but is not specifically
measured for it.
To achieve individual flow rates and optimal flow conditions, the driving parameters need to be tested, optimized and
confirmed by testing under full application conditions. The typical flow rates given by us have been determined using
an mp-x controller with SRS wave form. Please refer to the corresponding manual for operation of the mp-x
controller.

Rev. 3.1 (08.2020)
If lower flow rates are required, it is advisable to use a restrictor for throttling and to operate the pump at the
recommended parameters.
As a general experimental approach, we recommend a high amplitude at varying frequencies. The performance
depends on the environmental conditions.
Combination of micropumps
The micropumps can be combined to achieve higher flow rates or pressure than the single unit can generate.
With series connection, the pressures add up.
With parallel connection, the volume flows add up.
All values are approximate and no guarantee of specific technical properties.
Changes in the course of technical progress are possible without notice.
