2Special Features
2.1 Speed Control Function
The flow rate of the pump can be changed by adjusting the motor
speed. There are three types of speed control functions available for
this series of pumps: knob speed control type, PWM speed control
type and frequency speed control type. Please refer to Chapter 5
Electrical Connection for specific usage of different speed
adjustment methods.
2.2 Warning Function
Feed back the working status through working status indicator light.
1. When the light remains green, it means that the power supply is
normal and the pump is not working;
2. When the green light flashes, it means the pump is working
normally; the faster the green light flashes, the higher the pump
speed, the greater the output flow;
3. When the light remains red, it means the pump is working
abnormally;
4. When the positive and negative poles are reversed, the indicator
light is off, the pump does not work, but it will not damage the
pump.

2.This series of air pumps all have the characteristics of low operating vibration.
3.The noise data of the simplified version and the standard version are not
specified. For the noise data of the premium version, please refer to the latest
information.
3.3 Life-time Test Conditions
1. Lifetime test conditions: In a clean, non-corrosive laboratory, the
inlet and outlet are directly connected to the atmosphere, and they
operate continuously around the clock. Unless otherwise specified,
the technical parameters are all measured values at 25°C and
standard atmospheric pressure.
2. Laboratory conditions: The ambient temperature 5℃ ~33℃,
fluctuates with the climate; the relative humidity 50%-85%,
fluctuates with the climate.
Note: When the pump is running, the connecting pipeline should be kept as
unobstructed as possible. The inlet can carry a large load, but only short-term
blockage is allowed. Long-term blockage may damage the pump. The outlet

C09 Flow Control Vacuum Pump Series User Guide

6
of the pump must be unobstructed, and there must be no components in the
outlet hose that hinder the discharge of gas!
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.
3.5 Materials
1. The materials of the wetted parts: the medium will be in contact
with EPDM rubber and SPS, both of which have certain corrosion
resistance. Please check the chemical resistance and compatibility of
the medium according to the wetted material.
2. The material of the pump body is fiber reinforced nylon, and the
material of the shock absorb foot is PVC.
3.6 Filtration
When the pump works for a period of time, the dust contained in the
medium will accumulate in the pump chamber, impair the air
tightness of the pump, and reduce the flow rate and vacuum degree.
A filter must be equipped at the inlet. Practice indicates that
generally clean gas we regard clean still contains dust and impurities,
and it also needs to be filtered to ensure the normal operation of the
internal sophisticated air-tight components.

3.7 Parameter Curve
Vacuum degree-flow curve, there are individual differences between
different micro pumps, this curve is a statistical value, only used as
a technical reference for users to confirm the working point. The
"flow" mentioned in this section refers to the "average flow".
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.

3.8 Starting Current
The starting current curve is measured under the working condition
that the inlet and outlet are directly connected to the atmosphere,
and there are certain individual differences between different micro
pumps. This curve is a statistical value, which is only used as a
technical reference when users determine the power supply system,
and is not as acceptance data.

5Electrical Connection
5.1 Brief Description of Types
1. Knob speed control type: A digital rotary encoder is used for
input control to realize digital control of start and stop, acceleration
and deceleration of the pump. Adjust the knob clockwise or
counterclockwise to control the speed increase or decrease, and
press the button to control the start and stop of the micro pump.
2. PWM speed control type: external PWM signal, realize speed
control by changing the duty cycle of the signal, and built-in
closed-loop control function to ensure stable speed and output.
3. Frequency speed control type: external square wave signal,
realize speed control by changing the frequency of the signal, and
built-in closed-loop control function to ensure stable speed and
output.

Note: The wire color in the above figure may be different from the actual wire
color,please connect according to the above figure.
The red wire of the power connector is connected to the positive
pole of the DC power supply, the black wire is connected to the
negative pole of the power supply, and the speed regulation
connector is connected to the knob circuit board through a wire
harness. This type of pump is equipped with a speed control knob
switch (rotary encoder) as standard. Rotate the knob clockwise to
increase the motor speed. When it reaches the maximum speed, if
continue to rotate clockwise, the motor will maintain the maximum
speed. Rotate the knob counterclockwise to decrease the speed.
When it decreases to the minimum speed, if continue to rotate
counterclockwise, the motor will maintain the minimum speed.
Press down the knob to start or stop the pump. The pump also has a
state memory function, when the pump is started, it will run at the
speed before the last stop.
Attachment: Installation instructions for speed control knob switch
(1) Nut installation: first make a hole with a diameter of about 7mm
on the mounting plate, then unscrew the nut on the encoder and
remove the gasket, insert the knob of the encoder into the opened
hole on the mounting plate, and finally install the washer and screw
back the nut.

(2) Screw installation: Use two M3 screws to pass through the screw
holes and washers of the speed control knob switch, and then fix
them to the mounting plate.
Figure 5-3 Screw Installation
Note: In order to avoid welding protrusions on the back of the speed control knob
switch to affect the installation, we have attached two Φ3*Φ7*3 insulating
washers in the installation accessories. Two M3 screws are usually used for the
screws, which need to be prepared by the user.

runs at the maximum speed, and
when the PWM input continues to be
high, the micro pump stops;
b.When the duty cycle changes from
low to high in the range of 0% to
90%, the speed changes from the
highest speed to the lowest speed;
c.When 95%<duty cycle≤100%, the
micro pump will stop;
