Micro Vacuum Pump and Micro Air Pump Selection Guide | BODENFLO

Table of Contents

With the development of industry, compact, oil-free and environmentally friendly miniature vacuum pumps, miniature air pumps and miniature water pumps are becoming more and more widely used.
How can you choose the most suitable product among the wide range of miniature pumps?

This article will provide you with professional selection guidance from several aspects.

micro air pump selection guide

Depending on the usage of the miniature pumps, they can be divided into 3 categories.

1. A miniature air pump is used to output compressed air.

In simple terms, this means that it is used only for pumping and inflating, and the pump’s suction port is basically not used.

This is a relatively simple case, according to the output pressure from high to low optional: BD-01A, BD-02AB, BD-02A, BD-03AB, BD-03A, BD-04AB, BD-04A, BD-07AB, BD-07A, BD-08AB-S, BD-08AB-D, BD-08A-S, BD-08A-D.

Of course, also refer to the flow indicators and other related technical parameters.

2. Suction with a micro vacuum pump.

In simple terms, this means that it is simply used to extract and suction air, the pump outlet is basically not used.

According to the output vacuum value in descending order, you can choose: BD-01V, BD-02VB, BD-02V, BD-03VB, BD-03V, BD-04VB, BD-04V, BD-07VB, BD-07V, BD-08VB-S, BD-08VB-D,BD-08V-S, BD-08V-D.

Of course, reference is also made to flow indicators and other relevant technical parameters.

According to different working conditions, miniature pumps can also be divided into those with a small load (the resistance of the pump must not be too large) and those with a large load (the suction port allows a large resistance).

In brief, for miniature vacuum pumps with small loads you can choose from the BD-01V, BD-02VB, BD-02V, BD-03VB, BD-03V, BD-04VB. for miniature vacuum pumps with large loads you can choose from the BD-04VB, BD-04V, BD-07VB, BD-07V BD-08VB-S, BD-08VB-D.

According to different working conditions, miniature pumps can also be divided into those with a small load (the resistance of the pump must not be too large) and those with a large load (the suction port allows a large resistance).

In brief, for miniature vacuum pumps with small loads you can choose from the BD-01V, BD-02VB, BD-02V, BD-03VB, BD-03V, BD-04VB. for miniature vacuum pumps with large loads you can choose from the BD-04VB, BD-04V, BD-07VB, BD-07V BD-08VB-S, BD-08VB-D.

The size of the resistance of a miniature pump can be determined empirically using simple methods, for example the following are all cases where the load is large (i.e. the pump has a large resistance at the suction port).

  • There are filters, mufflers, solenoid valves, check valves, air switches and other components on the pipeline.
  • The suction end of the mini pump has to be connected to a very long pipe, or a large pipe to a small pipe, many bending points in the pipe, etc.
  • The pump’s suction port is connected to a suction cup for adsorbing objects.
  • etc.

3. Pumping water or liquids with a miniature water liquid pump.

Simply put, miniature water pumps are self-priming and do not need to be primed. This is a relatively simple case and is available in the following options from largest to smallest pumping volumes. BD-01W, BD-02WB, BD-02W, BD-03WB, BD-03W, BD-04WB, BD-04W BD-07WB, BD-07W.

Of course the self-priming height and other relevant technical parameters.

Please consider, depending on the use case.

1. The temperature of the medium of the miniature pump

Depending on the temperature of the medium gas passing through the pump, choose whether you want a normal or a high temperature type.
For high temperature miniature pumps, we recommend the BD-08 series made of aluminium alloy.

2. Electromagnetic interference of the miniature pump

If there is a precision circuit to control the mini-pump, depending on the circuit’s ability to resist interference, you can choose a version of the mini-pump with low electromagnetic interference.

Export to Europe and the United States, need CE certification, it is recommended that customers in Europe and the United States can choose a brushless motor micro pump, electromagnetic interference is low.

3. The life of the miniature pump

Depending on the working time of the miniature pump, choose the normal type (brush motor) or the long life type (brushless motor).

The BODENFLO Model Explanation

  • Distinguished by series, divided into 01-08 series.
  • By application, divided into miniature air pumps (only using the air outlet, not the suction port), miniature vacuum pumps (only using the suction port and not the exhaust port), miniature water pumps (only using the suction port)
  • Distinguished by the type of motor, divided into brushed and brushless models.
  • Distinguished by the number of pump heads, divided into single and double heads (only 08 series).
