The BD-04 brushed series offers:
- Flow:11–20 L/min
- Pressure type:5–3.5 bar
- Vacuum type:-75 to -80 kPa
- Voltage:6V / 12V / 24V
- Power:7–16 W
- Noise:50–65 dB
- Brushed motor life:1000 hours
Why This Small Brushed DC Diaphragm Pump Series Fits Compact OEM Equipment
The BD-04 brushed platform is designed for products where pump size, stable output, and practical integration matter more than simply chasing the highest catalog number.
For many OEM devices, the real requirement is not only pressure or vacuum. The system also needs:
- stable airflow or suction
- practical voltage matching
- compact mounting structure
- reliable output in real working conditions
- easier integration into embedded equipment
That is why the BD-04 brushed series works well as a shared compact platform for both pressure and vacuum versions in portable and built-in equipment.
Core Selling Points of This Brushed Mini DC Air Pump and Vacuum Pump

What Applications Is This Brushed DC Air Pump and Vacuum Pump Suitable For?
1. Beauty and Personal Care Devices
Compact beauty devices often require stable suction or airflow in a small installation space. The key concern is usually controllability, smooth operation, and integration flexibility rather than only peak output.
Key parameters: compact size, stable suction or airflow, smooth response, low-noise system integration
Recommended configuration:
- Vacuum type: BD-04V
- Pressure type: BD-04A
2. Portable Medical and Laboratory Devices
Portable instruments need compact pumps that support stable air transfer, vacuum generation, or pneumatic support in embedded systems.
Key parameters: compact size, stable output, voltage matching, media compatibility
Recommended configuration:
- Pressure requirement: BD-04A
- Vacuum requirement: BD-04V
3. Small Industrial and Analytical Equipment
Compact industrial systems often need moderate pressure or vacuum with limited space and easier wiring options.
Key parameters: flow stability, pressure or vacuum level, installation space, working mode
Recommended configuration:
- Pressure system: BD-04A
- Vacuum system: BD-04V
How Do I Choose the Right Version of This Custom DC Pump?
- If you need quieter and more stable operation, choose a brushless version.
For beauty devices used close to the face or skin, low noise and stable performance are very important. A brushless pump is usually the better choice because it offers smoother operation, longer life, and a better user experience.
- If you need adjustable suction or airflow, choose a PWM control version.
Many beauty devices require different working levels for different treatment modes. A PWM-controlled pump makes it easier to adjust suction or airflow and achieve more precise control.
- If the pump may contact moisture, mist, or chemical residue, choose suitable wetted materials.
For beauty applications involving humid air, skincare residue, or special media, selecting appropriate materials such as EPDM, FKM, or PTFE can improve durability and reduce the risk of early failure. - If your working media includes moisture or aggressive gas, upgrade sealing materials.
EPDMand FKMshould be selected according to the actual medium and environment. This follows the material-selection logic required by your page planning document. - If your system must run continuously, verify temperature rise and real load point.
Continuous operation should always be checked under final tubing, pressure, or vacuum load conditions.
Real Product Cases Using This Brushed DC Air Pump and Vacuum Pump
Case 1: Portable Pressure Therapy Device
Product background
This type of device needs a compact air pump to generate stable pressure in a limited internal space.
Core requirement
The pump must provide practical airflow, moderate pressure, and easier voltage matching for an embedded pneumatic system.
Application challenge
The product structure is compact, so the pump cannot be oversized. At the same time, the system still needs enough pressure output for stable air-path support.
Recommended pump solution
For this type of product, BD-04A is the more suitable brushed version because it can provide 2.5–3.5 bar pressure with 11–20 L/min flow in a relatively compact structure.
Application result
It is suitable for compact pressure-support products that need a balance of output capability, installation flexibility, and practical OEM integration.
Case 2: Beauty Suction Device
Product background
Beauty and personal care devices often need a compact vacuum source for suction, holding, or negative-pressure treatment functions.
Core requirement
The pump must fit into a small housing while still providing useful vacuum performance and stable suction response.
Application challenge
If the pump is too small, suction may be weak. If the pump is too large, the product structure, noise, and layout become harder to control.
Recommended pump solution
For this type of product, BD-04V is the more suitable brushed version because it provides -75 to -80 kPa vacuum with 11–20 L/min reference flow, which fits compact suction systems better than a larger pump platform.
Application result
It is suitable for personal care products that need compact vacuum generation, stable negative pressure, and easier integration into small equipment.
