BD-03AB/BD-03VB Small Air Pumps Negative Pressure Vacuum Pumps

Pump Construction Principle:

Miniature diaphragm pumps use the technology of a DC motor driving a rubber diaphragm through an eccentric wheel.

Pumps Features:

BD-03 series is a miniature diaphragm pump for air and vacuum, the most important feature is the small size and high flow rate. It is mainly used for inflating and suction. More features of the air pump are as follows.

• Efficient and durable design
• Smallest size and lightest weight
• Oil-free and non-contaminating medium
• Maintenance-free, easy to operate and install
• Excellent air tightness
• Long lifetime

Model Composition:

We offer both brushed and brushless motors, with high quality DC brushless motors for 3000-5000 hours and brushed motors for 1000 hours.

With the optional brushless DC motor, we also offer a pulse width modulation (PWM) option. This unique feature is ideal for applications that require precise control of pump output.

Typical Parameter:

Model BD-03AB positive pressure pump and BD-03VB negative pressure pump products, consisting of long-life brush motor and POM material pump body, the following parameters are common in the market and the most shipped parameters, we also support other parameters customization, welcome to consult.
