Product Overview
BD-02AB/VB is a compact brushless diaphragm gas pump platform developed for small medical equipment that needs controlled gas delivery, light pressure output, or negative-pressure support inside a limited structure.
This brushless series includes two working directions:
BD-02AB → pressure type micro diaphragm gas pump
BD-02VB → vacuum type micro diaphragm vacuum pump
BD-02AB supports pressure airflow, while BD-02VB supports suction, evacuation, and vacuum testing.With a compact square pump head, small brushless motor, top air ports, and 53 × 40 × 24.3 mm body, both versions are easy to integrate into portable or desktop nebulizer equipment.
Core Selling Points of This Mini Diaphragm Gas Pump
- Square Pump Head Structure for Compact Nebulizer Layouts
- Top Dual-Port Design for Cleaner Gas Tube Routing
- Low-Flow Pressure Output for Nebulizer Air Supply
- Vacuum Version for Auxiliary Suction and Gas-Path Testing
- Accessory-Friendly Design for Medical OEM Integration

How Does This Diaphragm Gas Pump Perform Under Real Load?
This diaphragm gas pump should be selected according to the complete nebulizer gas path, not only according to open-flow data. A pump that looks sufficient in open-air testing may show lower working flow after the tube, filter, medication cup, and atomizing structure are connected.

What Are the Dimensions and Installation Details
The pump has a square pump head and top air-port layout. During installation, engineers should reserve space for the pump head, motor, wire outlet, tube bending radius, and optional accessories. The tube should not press against the pump shell or bend sharply near the inlet and outlet ports.

Which Media and Materials Is This Mini Diaphragm Gas Pump Compatible With?
BD-02AB/VB is mainly designed for air and clean gas. It should not transfer liquid directly.
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 Diaphragm Gas Pump Suitable For?
BD-02AB/VB is a compact brushless diaphragm gas pump platform for small equipment that needs controlled airflow, light pressure output, vacuum suction, or clean gas-path control in limited space.
1. Medical and Healthcare Equipment
In medical and healthcare equipment, this diaphragm gas pump can support compact airflow supply, light pressure assistance, auxiliary suction, and small chamber evacuation. BD-02AB provides 1–3 L/min flow and 50–150 kPa pressure, while BD-02VB offers -30 to -65 kPa vacuum. Its compact body, brushless motor, EPDM sealing, and optional accessories suit embedded medical gas-path modules.
2. Testing and Detection Equipment
In testing and detection equipment, BD-02AB/VB can provide a compact air or vacuum source for sensor response testing, leakage inspection, gas-path control, and small sealed-chamber evaluation. BD-02AB supports low-flow pressure input, while BD-02VB supports vacuum decay testing or negative-pressure inspection. Optional check valves, air filters, and silicone shock brackets help improve module stability and installation flexibility.
How Do I Choose the Right Air Pump or Vacuum Pump Version?
- Choose the air pump version when the gas path needs positive output.
- Choose the vacuum pump version when the system needs suction or air removal.
- Check the top-port direction before confirming the tubing layout.
- Match accessories according to the real gas-path risk.
- Confirm wire routing and mounting space before sample approval.
Real Product Cases Using This Diaphragm Gas Pump
Case 1: Portable Nebulizer Air Supply Module
A customer developed a portable nebulizer device that needed a compact air source in a limited internal space. We recommended BD-02AB 3L, 12V DC, with 3 L/min flow, 150 kPa max pressure, and ≤0.3A no-load current. The nylon pump head/body, EPDM diaphragm and valve, and inlet air filter supported stable air-path protection. This configuration maintained enough pressure reserve after engineers connected the tube, filter, and atomizing structure.The compact square pump head and brushless motor also made internal integration easier.
Case 2: Nebulizer Component Vacuum Leakage Test Fixture
A medical equipment manufacturer needed a compact vacuum source for testing nebulizer gas-path components before final assembly. We recommended BD-02VB 1.5L, 12V DC, with 1.5 L/min flow, -50 kPa vacuum, ≤0.2A no-load current, EPDM sealing, and a check valve. This setup supported repeatable leakage inspection and compact integration of the pump, sensor, tubing, and anti-backflow structure.
