3.3 Typical flow characteristics mp6 and mp6-pp

3.4 Final inspection

After production the micropumps have to pass a final inspection. They are tested concerning the maximum
flow and back pressure and the self-priming characteristic (conditions: suction pressure < 10 mbar; DI
water; settings mp-x: 100 Hz, 250 V, SRS, the max. flow rate will be reached after a few minutes of
operation time).

Measurement conditions

Pump media: DI-Water

Increase in amplitude linearly increases the flow rate to the

maximum.
The amplitude defines the stroke of the actuator and therefore the
displacement of the pumping media per pump cycles.

The flow rate of the pumps shows a linear dependency on the back
pressure.

At 0 mbar back pressure the maximum pump rate can be achieved
and at the maximum back pressure the flow rate is de

creased to

0 ml/min.

Rising frequencies result in a maximum flow rate at resonance
frequency. At frequencies above the resonant point the flow rate
decreases again.

The resonance frequency and the

maximum flow rate strongly depend on
the viscosity of the media.
The lower the viscosity, the higher the
maximum flow rate and the resonance
frequency.

4. Operating the micropump

In this chapter 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.

4.1 Connecting the micropump

Please connect suitable tubes to the inlet and outlet. The tubing should have an inner diameter of ~1.3 mm
for the mp6 and ~1 mm for the mp6-pp. The micropump has to be connected to a suitable controller as
described in the next sections.

On both the mp6 and mp6-pp 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 a 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 gets 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.

4.1.1 Connecting the mp6/mp6-pp to the cable

The mp6/mp6-pp pump can be connected via a standard electrical connector manufactured by Molex. The
layout of the connector and pin assignment of the mp6/mp6-pp is as shown below. Each piezo (P1 / P2) has
a single lead for the negative (-P1/-P2) and the positive (+P1/+P2) supply voltage.

Subject to change without further notice

The recommended connector is a 4 pin 1.25 mm pitch FCC connector manufactured by Molex, part number
39 53 2045. 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 mp6/mp6-pp and Molex, refer to following three figures. Orientate both components as
indicated on the first picture, the mp6/mp6-pp 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).

Step 1 Step 2 Step 3

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 of both pump and connector

with e.g. silicone might be necessary

- fixation of the Molex connector in the final assembly is recommended

4.2 Cleaning the system

The pump can be washed with water, alcohol (iso-propanol) or if necessary with weak acid by pumping or
by flushing with the help of a syringe.

!! Only use the syringe pulling from the outlet in pumping direction!!

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. As an example, typical driving
parameters are listed below to give a general orientation for testing. The parameters have been obtained
using the mp-x controller with the SRS signal preset. Please refer to chapter 5 for operation of the mp-x
controller.

Target flow rate Amplitude Frequency Target flow rate Amplitude Frequency

7 ml/min 250 V 100-110 Hz

2 ml/min 220-240 V 20 Hz

6 ml/min 250 V 80-9 0Hz 1 ml/min 125-135 V 20 Hz

5 ml/min 250 V 55-65 Hz 0,5 ml/min 90-100 V 15 Hz

4 ml/min 250 V 40-50 Hz 0,25 ml/min 85-95 V 8 Hz

3 ml/min 250 V 30-35 Hz 0,1 ml/min 80-90 V 3 Hz

As a general guideline the amplitude should be kept as high as possible while varying the frequency.

4.3.1.2 Medium: air

Driving the micropump with the controller mp-x at 300 Hz with 250 V, flow rates of 18 ml/min and
backpressures of up to 100 mbar have been achieved.

In general, for driving the pump with air, higher frequencies should be used than for water. To minimize
audible noise, using the sine signal is recommended. As this is preliminary data, please contact us for more
information when you intend to use the pump with air.

5.5 Installation of the drivers “USB Micropump Control” and “USB Serial Port”

In order to control the mp-x with a computer, a driver needs to be installed. The installation is done in two
steps. First, the USB driver is installed. Second, the driver for the mp-x itself is installed which can be used
as a serial interface from different software packages.

5.5.1 For older operating systems including “Windows XP”

Step 1: Connect the control unit with the USB port and turn it on. A message appears that new

hardware was found and the hardware assistant starts automatically. Please click “next” to
continue.

Step 2: Choose “find a suitable driver for the device” and click “next” to continue.

Step 3: Activate the box “search for new driver” and insert the accompanying CD.

Step 4: After you have found the driver “USB Micropump Control”, click “next” to start the installation.

Maybe a message appears that the windows-logo-test has failed. This warning can be ignored.
After installation click “complete” to finish the installation.

Step 5: After finishing the installation the assistant will start again to install the corresponding USB

serial port by repeating the description.

5.5.2 For operating system Windows 7

Dependent on the individual system settings, different steps for installation might be necessary. The
procedure applies in general also for Windows Vista.

Step 1: Log in with administrator rights

Step 2: Connect the control unit with the USB port and turn it on. A message appears that new

hardware was found. This dialog does NOT allow to install the software.

Step 3: Open the device manager and double click the item "USB Micropump control" filed under

"additional hardware" (or similar). In the pop up window click on "update driver" and select the
directory including the driver files (e.g. the cd rom drive). It needs to be confirmed that the
driver should really be installed as it has no digital signature.

Step 4: Second the serial port needs to be installed. Starting with step 2) again, a device named "USB

serial port" will be listed. The drivers need to be installed as described above.

Step5: Finally in the device manager the number of the serial port (e.g. COM 4) is listed, for further use

of the device with application programs, the port number should be noted.

5.6 Operation via USB port (after installation of the drivers)

The driving parameters can be set via your PC. For this purpose you can use any software (or programming
language) capable of sending commands to a COM-Port, like the Hyperterminal as shown below.
As the Hyperterminal is not available in Windows 7 anymore, other free terminal programs are
recommended like PuTTY for example http://www.putty.org/

Step 1: Connect the control unit to your computer and turn it on.

Step 2: Start Windows Hyperterminal. Every new session has to be titled.

Step 3: Choose the com-port specified in the device manager.

Step 4: The connection-settings have to be (9600, 8, n,1).

Possible commands (followed by the enter key)

bon turns the micropump on

boff turns the micropump off

F(1-300)

F100

sets the required frequency between 1 and 300 Hertz:

…for example 100 Hertz.

A(0-250)

A100,5

sets the required amplitude between 5 and 250 Volt:

…for example 100,5 Volt. (in increments of 0.5 Volt)

MS sets signal form modus (S)ine

MR sets signal form modus (R)ectangle

MC sets signal form modus SRS

(enter key) displays present settings of the control unit

The unit can also be used via LabView, Matlab or other programs. Using the unit with LabView, please
ensure that the “NI-Serial” package is installed. Normally the package is installed on yoursystem together
with LabView, but sometimes this option is skipped during install.
It can be downloaded on the National Instruments website:
http://joule.ni.com/nidu/cds/view/p/id/2316/lang/en

Afterwards it is possible to select the right COM-port for your mp-x in the VISA resource name.

On request we can send a package of LabView-Routines as an example of implementation. We do however
not offer a complete software environment for the use of the mp-x controller. Development of specific
software routines can be offered on request.

6. The mp6-OEM controller

The mp6-OEM is a small, easy to use low cost driving circuit developed for the mp6 or mp6-pp micropump.
It generates up to 235 V peak to peak voltage from a 3-5 V supply.
Its low power consumption makes it ideal for battery powered handheld devices or even solar powered
devices. The module can be integrated into a PCB design like a 14 pin DIL package.
Build in interface allows the user to adapt frequency and/or amplitude to its application by the use of a
few additional components or a microcontroller.
In order to locate Pin 1, please refer to the following figure. Looking onto the mp6-OEM from the top with
the black encapsulation on the left side, Pin 1 is in the lower left. The pin is as well marked by a small white
spot.

6.3 Connecting the mp6 to the mp6-OEM controller

The mp6/mp6-pp pump can be connected to the mp6-OEM via a standard electrical connector
manufactured by Molex, see chapter 4.1.1

6.4 Typical schematics

6.4.1 Fixed pump rate

The mp6-OEM can drive the mp6/mp6-pp without the need of external components. In this case the pumps
frequency and amplitude is fixed determined by internal components to 235 V and 100 Hz.

Schematic 1: Fixed amplitude of 235 V and fixed frequency of 100 Hz ±10 % with internal components.

6.4.2 Pump rate set by external components

In this example the frequency and the amplitude is set by external components. The amplitude can be
varied from approximately 85 V to 235 V peak to peak. The frequency can be changed from 25 Hz to 120
Hz. For higher frequencies the amplitude will decrease. Lower frequencies are also possible but stability of
the output signal needs to be checked.

To set the amplitude, either a potentiometer with 10 kOhms, or a voltage divider of two resistors R1 and R2
as shown in the schematic 2 can be used. The voltage at the amplitude pin can be calculated with the
following formula (voltage divider)

The relation between the voltage at the amplitude pin and the output voltage is shown in table 7.1

Schematic 2: Frequency and amplitude set with external components

Table 6.1 : Behavior of output voltage according to external circuitry

To set the frequency, a capacitor C1 between in the nF range can be used as shown in the schematic 2
above. Typical capacitor values are shown in the following table 6.1.

For frequencies that are lower than 20 Hz, an external frequency signal needs to be applied as described in
chapter 6.4.3.

Table 6.2 : Typical capacitor values for different pump frequency values

6.4.3 Pump rate control via microcontroller

To control the mp6-OEM with a microcontroller, an external clock with four times the desired frequency
connected to the CLOCK pin can directly set the output frequency. In this case the pump frequency can be
decreased down to the single Hz range. Working at pump frequencies below 25 Hz, the duty cycle of the
frequency signal needs to be high (95% on time) to result in an appropriate output signal.

The amplitude can either be adjusted by an analog voltage according to table 6.2, or by an equivalent PWM
signal with a frequency between 0.2 and1 MHz connected to the AMPLITUDE pin (see table 6.2 for details).
The PWM signal should be higher than 1.3 V to make the output solely dependent on the duty cycle of the
PWM signal.

For a minimum of power consumption the electronics can be switched off by applying zero volts to the
AMPLITUDE input and the SHUTDOWN port, but the most efficient way is to cut the power supply.

6.7 Noise reduction

If the noise generated by the pump is critical a series resistor of 2-10 kΩ in the P1+ and the P2+ line
between the mp6-OEM and the pump will help. There is no limit for the resistor value but it will decrease

the maximum pump performance.

7. The mp6-EVA evaluation board

The evaluation board enables the simple use of the mp6 based on the mp6-OEM controller. Next to preset
standard parameter (235 Vpp, 100 Hz) the mp6-EVA also allows to adjust the pump parameters, partly by
external tuning. As the supply voltage of the module can be provided via USB (no data interface), just
attach it to a USB power supply and start the evaluation. Alternatively it can also be supplied by a 2.5 – 5 V
voltage source.

7.1 Safety notice

The mp6-OEM generates voltages of up to 250 V peak to peak. All parts of the mp6-EVA evaluation board
can carry voltages in this range. Therefore the board should only be used by qualified personal. Although
the output power of the module is very low, proper insulation according to the application conditions needs
to be considered by the customer. This especially applies to the lower side of the PCB. Contact with water
or other liquids needs to be prevented. The pump must not be changed while a driving voltage is applied to
the board.

7.2 Electrical specifications mp6-EVA evaluation board

As the evaluation board is based on the mp6-OEM module, all electrical characteristics and specifications
of this product must be considered. Please see chapter 6 of this manual for more details.

7.3 Functional elements

Elements are listed with their names according to the printed description on the PCB

8. Passive check valve mp-cv

When the micropump is switched off, a back flow of the pumping medium, depending on a differential
pressure between in- and outlet is possible. In order to impede a back flow Bartels Mikrotechnik offers a
passive check valve integrated in stainless steel.
The connection of the valves with the micropump can be done easily with suitable tubing. The valve should
be placed between the micropump and the outlet reservoir.

Dimensions:

The valves are individually marked regarding the free flow direction.

Technical specifications:

Please note that the volume flow of the micropump will be influenced by the check valve.

9. Trouble shooting

Observation

Trouble shooting

Maximum flow rate

cannot be achieved

- Gas bubbles within the system, the compressible gas volume
in the pump can result in decrease of pump rate = system
should be primed with a syringe.
Manual priming should be carried out by flushing the pump
with the help of syringe. Only pull the fluid from the outlet in
pumping direction. Do not exceed 1 bar of internal pressure.

- Tubing is too long = shorten tubing

- Tubing diameter is too small = use appropriate tubing with

an inner diameter of 1.3 mm for the mp6 and 1 mm for the
mp6-pp

- Back pressure is too high = reduce pressure or lower outlet
reservoir

- Check signal form used to drive pump = highest flow rate is
achieved by SRS signal and at resonance frequency (100 Hz
for water)

- The flow rate is viscosity dependent as described in 3.2

Non-linear flow behavior

- The linear range of the pump characteristic is described for
selected media in 3.2

- Gas bubbles in the pump act as compressible volume and
when they are digested through the pump this can lead to
non-linear flow behavior = system should be primed with a
syringe as mentioned above

Fluid is flowing through the system

although pump is switched off

- The valves inside the pump are opening and closing by
differential pressure of in- and outlet = lower in- or outlet
reservoir to avoid hydrodynamic behavior or add check valve
as described in chapter 9.

No buzzing sound =

pump is not working

- Please check if the mains adaptor is correctly connected

- Please check if the connection between pump and the Molex

connector is correct according to chapter 4.1.1

- Defect piezo actuator = contact Bartels Mikrotechnik for
support
