24V Vacuum Pump 3–6LPM Low Vibration -70kPa Miniature Diaphragm Air Pump BD-03VB BODENFLO

Designed for compact suction, air sampling, and negative-pressure applications, the BD-03VB Series combines a 24V brushless motor, 3–6 L/min airflow, and up to –70 kPa vacuum in a compact diaphragm pump platform. Three performance options are available for different vacuum and airflow requirements.

Key Features of 24V Brushless Vacuum Pump

• Longer Service Life: Brushless DC motor reduces motor wear and provides a service life of 3,000–5,000 hours.
• Up to –70 kPa Vacuum: Provides strong suction for compact vacuum, sampling, and air-extraction systems.
• 3–6 L/min Flow Options: Choose from 3, 4, or 6 L/min models to match different vacuum and airflow requirements.
• Easy Installation: Includes a silicone mounting bracket for flexible mounting positions and orientations.
• Reduced Vibration & Noise: Silicone mount helps isolate pump vibration and reduce noise transmitted to the equipment.
• Oil-Free Air Path: No lubricating oil is required in the pumping chamber, helping maintain a clean air path.
  

Common Applications:

• Air & Gas Sampling: Provides vacuum and airflow for environmental monitoring, gas analysis, and sampling equipment.
• Compact Vacuum Systems: Generates negative pressure for small vacuum and air-extraction systems.
• Vacuum Holding: Provides suction for lightweight holding and handling applications within the pump's operating range.
• Testing & Analytical Equipment: Supplies vacuum and controlled airflow for instruments and measurement systems.
• Portable Equipment: Compact size and 24V DC power simplify integration into space-limited devices.
  

Package & Shipping

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