12V Air Pump 3–6 L/min High Pressure 2–3 Bar Micro Diaphragm Pump BD-03AB BODENFLO

Designed for compact air pressure and transfer applications, the BD-03AB Series combines a 12V brushless motor, 3–6 L/min airflow, and 2–3 bar pressure performance in a compact micro diaphragm pump platform. Three versions are available with different flow, current, and pressure levels while sharing the same installation dimensions.

BD-03AB3L Technical Specifications:

• Name: 12V Air Pump
• Model: BD-03AB3L
• Rated Voltage: 12V DC

BD-03AB4L Technical Specifications:

• Name: Micro Diaphragm Pump
• Model: BD-03AB4L
• Rated Voltage: 12V DC
• Current: ≤0.4 A
• Max Pressure: ≥2.5 bar (250 kPa / 0.25 MPa)
• Max Flow: ≥4 L/min (4 LPM / 240 L/H)
• Noise: ★★

BD-03AB6L Technical Specifications:

• Name: DC Air Pump
• Model: BD-03AB6L
• Rated Voltage: 12V DC

Key Features of Micro Diaphragm Pump:

• Brushless DC Motor: Reduces motor wear and provides a service life of 3,000–5,000 hours.
• High Pressure Performance: Three models provide maximum pressure from 2 to 3 bar for different pressure requirements.
• 3–6 L/min Airflow: Available in 3 L/min, 4 L/min, and 6 L/min versions for different airflow demands.
• Flexible Silicone Mount: Each pump includes one silicone mounting bracket, allowing flexible mounting positions and orientations while helping reduce vibration and structure-borne noise.
• Vibration & Noise Reduction: The silicone mount helps isolate pump vibration and reduce noise transferred to the equipment.
• Oil-Free Operation: The diaphragm structure provides clean air transfer without lubricating oil in the airflow path.
  

Common Applications:

• Compact Pneumatic Equipment: Provides pressurized airflow for small pneumatic devices and systems.
• Air Transfer Equipment: Suitable for equipment requiring continuous or intermittent air delivery.
• Pressure Supply Systems: Provides 2–3 bar positive pressure for compact air pressure applications.
• Testing & Measuring Devices: Supplies airflow for instruments and compact testing equipment.
• Portable Equipment: The 12V DC supply and compact dimensions support integration into portable devices.

Package & Shipping

• Package Includes: 1 × Micro Diaphragm Pump + 1 × Silicone Mounting Bracket
• Lead Time: Typically 3–5 working days for standard orders.
• Shipping: DHL or FedEx express shipping available.
