Real application feedback helps buyers understand how BD-05T0617LB performs in compact gas transfer and vacuum systems.
Germany | Analytical Instrument Engineer
Application: Gas sampling module
Feedback: The higher airflow and stronger vacuum range helped us test different sampling paths without changing the pump platform.
Finland | Medical Device Developer
Application: Suction and sampling module
Feedback: The brushless motor and compact structure made the pump suitable for our long-cycle device testing.
South Korea | Gas Detection Equipment Manufacturer
Application: Portable gas detection system
Feedback: The G1/8 thread interface and stable gas flow helped simplify our prototype integration.
Proper installation helps maintain stable airflow, vacuum performance, and service life during OEM integration.
Air Path and Filtration
Install a ≤30 μm inlet filter when the gas path may contain particles, dust, or liquid mist. Keep tubing and fittings sealed to reduce air leakage, pressure loss, or unstable sampling performance.
Mounting and Fixation
Bottom mounting uses 4 × Ø2.5 mm holes with 4.5 mm depth, recommended with M3 self-tapping screws. Side mounting uses 2 × R1.6 mm through holes with M3 screws for through-board installation.
Material and Operating Conditions
The standard pump head is PA66, with EPDM diaphragm and valve. For corrosive or special gases, confirm compatibility before sample testing. Operating environment is 5°C to 40°C, and medium temperature is 10°C to 60°C.
[BD-05T0617LB Dual Head Mini Diaphragm Air Pump Datasheet (PDF)]
A dual-head diaphragm air pump uses two pump chambers to provide higher airflow or stronger vacuum performance from one compact platform. Compared with a single-head design, BD-05T0617LB allows parallel connection for 17 L/min airflow or series connection for -95 kPa vacuum, helping OEM engineers simplify pneumatic design and reduce the need for multiple pumps.
The connection method depends on the system requirement. Parallel connection is recommended when higher airflow is required for gas transfer or circulation, while series connection is suitable when deeper vacuum is needed for suction or sampling applications. The final selection should consider chamber volume, tubing resistance, and response time.
The datasheet performance is measured under specific test conditions. Actual system performance may be affected by tubing size, fittings, filters, leakage, chamber volume, and pneumatic resistance. Testing the complete system helps identify whether the limitation comes from the pump or the application design.
Yes. The BD-05T0617LB is designed for long-term OEM operation with a brushless DC motor and low-maintenance diaphragm structure. Proper ventilation, suitable operating conditions, and correct system design help maintain stable airflow and vacuum performance over extended operation.
If your equipment needs a dual head diaphragm air pump but does not require brushless motor operation or 3.8 bar positive pressure, BODENFLO can recommend BD-05T0511L for evaluation. This model provides 12 V / 24 V operation, 11 L/min flow in parallel connection, -93 kPa vacuum in series connection, 1.5 bar max positive pressure, 18 W max power, 330 g weight, and 3000 h lifetime.
If you are developing medical sampling equipment, gas detection devices, analytical instruments, or compact air vacuum modules, BODENFLO can support pump selection, customization, sample testing, and long-term OEM supply.
