Miniature diaphragm pumps use DC motor technology to drive a rubber diaphragm through an eccentric wheel.
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
The life span of these small air pumps depends mainly on the type of motor used. 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:
Model BD-04A positive pressure pump and BD-04V 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.
