Product Overview
The BD-04 series is a compact brushed DC diaphragm pump platform designed for OEM equipment that needs stable air pressure, vacuum suction, or clean gas transfer in limited installation space.
This brushed series includes:
- BD-04A→ pressure type mini DC air pump
- BD-04V→ vacuum type mini DC vacuum pump
Both versions are designed for compact systems that need balanced flow performance, easier integration, and practical pressure or vacuum capability without moving to a much larger pump structure.
Core Selling Points of This Brushed Mini DC Air Pump and Vacuum Pump
1. One Brushed Platform for Pressure and Vacuum
2. Balanced Flow Output for Small Devices
3. Reliable Pressure Option for Air Pump Applications
4. Stable Vacuum Option for Suction Applications
5. Multiple Voltage Options for Easier System Matching
6. Compact Structure for Embedded Installation

Which Media and Materials Is This Mini Brushed Diaphragm Pump Compatible With?
The BD-04 series is intended mainly for air and clean gas transfer. Material selection should be based on actual media, humidity level, corrosion risk, and durability target.
Standard EPDM
| Media Type | Notes |
| Clean air | Standard application |
| Inert gas | Final compatibility should be confirmed by project |
| Mild moisture air | Cost-effective and suitable for general humid air conditions |
Enhanced FKM
| Media Type | Notes |
| Inert gas | Recommended when better chemical resistance is needed |
| Corrosive gas | Better chemical resistance and higher temperature resistance |
What Applications Is This Brushed DC Air Pump and Vacuum Pump Suitable For?
As a brushed DC diaphragm pump platform, the BD-04 series is suitable for compact equipment that needs either positive air pressure or negative vacuum suction.
1. Beauty and Personal Care Devices
Compact beauty devices need stable suction or airflow in limited space, prioritizing controllability, smooth operation, and integration. Recommended: BD-04V vacuum (15 L/min, -80 kPa) for suction/negative pressure, BD-04A pressure (11–15 L/min, 2.5–3 bar) for gentle or faster airflow.
2. Portable Medical and Laboratory Devices
Portable instruments require compact pumps for stable air transfer, vacuum, or pneumatic support. Recommended: BD-04A pressure 15–20 L/min, 3–3.5 bar for airflow/pressure, BD-04V vacuum 11–15 L/min, -75 to -80 kPa for suction.
How Do I Choose the Right Version of This Custom DC Pump?
1. If you need quieter and more stable operation, choose a brushless version.
2. If you need adjustable suction or airflow, choose a PWM control version.
3. If the pump may contact moisture, mist, or chemical residue, choose suitable wetted materials.
4. If your working media includes moisture or aggressive gas, upgrade sealing materials.
5. If your system must run continuously, verify temperature rise and real load point.
Real Product Cases Using This Brushed DC Air Pump and Vacuum Pump
Case 1: Portable Pressure Therapy Device
For compact devices needing stable pressure in limited space, BD-04A brushed pump delivers 15 L/min flow at 3 bar, offering practical airflow, moderate pressure, and easy voltage matching—ideal for pressure-support products with flexible OEM integration.
Case 2: Beauty Suction Device
Beauty and personal care devices often require a compact vacuum source that delivers stable suction without compromising product size or noise. The BD-04V brushed pump meets this need, providing 80 kPa vacuum and 20 L/min reference flow, making it ideal for small suction systems and easy integration into personal care equipment.
