12V/24V BD-04AB/BD-04VB Miniature Air Pumps

Pump Construction Principle:

Miniature diaphragm air pump is driven by a motor driven eccentric wheel to drive the diaphragm inside the pump to do reciprocating motion and the pump cavity one-way valve group open and close, circulating driven airflow, therefore generating negative and positive pressure.

Pumps Features:

BD-04 series is a miniature diaphragm gas pump, the largest feature is the small size, with mounting holes, a variety of pressure and flow options, mainly for inflatable, suction. More features of the air pump are as follows.

• Efficient and durable design
• Minimum size and lightest weight
• Oil-free and non-contaminating media
• Maintenance-free, easy to operate, easy to install
• Excellent air tightness

 

Model Composition:

We offer both brushed and brushless motors, up to 3000-5000 hours with premium DC brushless motors, and up to 800-1000 hours with  brush motors.

With optional brushless DC motors, we also offer Pulse Width Modulation (PWM) option. This unique feature is ideal for applications that require precise control of pump output

 

Typical Parameter:
