2Special Features
2.1 Speed Control Feature
The flow can be changed by adjusting the motor speed of the pump
(by adjusting the PWM duty cycle).
Or by ordering our company's special speed controller for micro
pump (model: TS-G12) to regulate the speed.
2.2 Warning Feature
The color of the indicator light displayed on the transparent bottom
case (as shown in Figure 2-1 and Figure 2-2) can feedback the
working status of the pump:
1. It is normal when the blue light flashes regularly;
2. When the light remains red, it is abnormal, i.e. the motor runs too
low;
3. When the red and blue lights alternately flash, it is abnormal , and
at this time,the motor speed is low and unstable;
4. The indicator light is off when the positive and negative
connections are reversed;
5. When the voltage is out of the working voltage range (3.2V～6V),
the indicator light is off.

Note:
1.Working voltage is 3.2V～6V, input voltage change will affect the load current;
2.Unless otherwise specified, the technical parameters are measured under the
conditions of temperature 25℃ and standard atmospheric pressure of 101kPa. For
products with other parameters and specifications, you can contact us to customize.
3.The parameters in the table are measured at the maximum speed of the motor
under rated voltage. When the motor speed changes, the pressure/vacuum level is
basically unchanged.
4.The peak flow rate in the table refers to the flow value measured with a rotameter,
and the average flow rate is measured with a soap film flow-meter.

latest information.
3.3 Life-time Test Conditions
In a clean, non-corrosive laboratory, the pump carries a full load(the
inlet is blocked and the outlet directly connected to the atmosphere),
and operates continuously around the clock. The ambient temperature
is 5℃ ～33℃, fluctuates with the climate; the relative humidity is
30%～90%, which fluctuates with the climate.
3.4 Working Conditions
1. Environment: Permissible ambient temperature range of the pump
is 0 ℃ ～ 50 ℃, permissible relative humidity is ≤90%, no
condensation. The pump should not be exposed to the sun, and
should work in a clean and ventilated environment.
2.Medium: Permissible gaseous media temperature range is 0 ℃ ～
50℃. The medium is allowed to be rich in water vapor, but cannot
contain particles or oil mist.
3. Load:
1) When used as a compressor: the outlet can run at full load ( i.e.
the inlet is completely blocked), but the applied load cannot exceed
the maximum discharge pressure of the pump; the inlet must keep
unobstructed.
2) When used as a vacuum pump: the inlet can operate at full load
( i.e. the inlet is completely blocked), but the applied load cannot

exceed the maximum vacuum of the pump; the outlet must be
unobstructed.
3.5 Materials
1. The materials of the wetted parts: reinforced nylon and EPDM
rubber, which have certain corrosion resistance. Please check the
chemical resistance and compatibility of the medium according to
the wetted material.
2. The pump body is made of reinforced nylon for plastic parts,
EPDM for elastomer parts and light-transmitting ABS for bottom
case.
3.6 Parameter Curve
Vacuum degree-flow curve, there are individual differences between
different micro pumps, this curve is a statistical value, only as a
technical reference for users to confirm the working point. The
"flow" mentioned in this section refers to the "average flow".
（to be updated……）
Note: 1. The maximum average flow rate of the curve will be slightly lower than the
nominal value, which is due to the resistance of the test pipeline components,
which leads to the attenuation of the flow;
2. The value of this curve is for reference only, not as a basis for product
acceptance.

4Product Model Description
4.1 Brief Description of Model Naming
Only basic type type available for this series of pumps.
Note: If the remarks starts with a letter, it means a special custom function. For
example, letter"GJ" means customized high-temperature medium function,
and "GH", means customized high-temperature environment function. If it
starts with a number, it means other information.

Note: More wiring will be added with more functions to be added into the
product,and this table will also be updated.
5.2 Logical Wiring Diagram
When the speed control function is not needed, the white connection
wire PWM input signal and the black connection wire can be
grounded together, the yellow wire must be insulated and wrapped,
and the micro pump will work at the rated speed.
Note: The speed feedback function is unavailable with the simplified version so
there is no yellow FG signal line.
When you need to use the PWM speed control function, you need to
use a signal source that supports PWM signal output (function
signal generator, MCU, PLC, etc.), connect the signal source output
to the white PWM input cable, and connect the PWM signal source
ground to the DC power ground. If you do not need to monitor the
speed feedback signal, the FG signal line must be insulated and
wrapped. The speed feedback function is unavailable with the
simplified version so there is no yellow FG signal line.

When you need to use the PWM speed control function and obtain
the FG feedback, you need to use a signal source that supports
PWM signal output (function signal generator, MCU, PLC and
other controllers) and an oscilloscope or host computer, and connect
the signal source output to the white PWM input. Connect the PWM
signal source ground to the DC power ground, connect the yellow
FG feedback signal line to the oscilloscope probe or the host
computer input, and connect the oscilloscope or host computer
ground wire to the black ground wire. If the FG signal wire is not
used, it must be insulated and wrapped. The speed feedback
function is unavailable with the simplified version so there is no
yellow FG signal line.
