These miniature diaphragm pumps work on the technology using a DC motor driving a rubber diaphragm through an eccentric. The life of these small air pumps depends mainly on the type of motor used. Use of high quality DC brushless motor can provide life up to 3,000 hours. Due to their compact size & light weight, these small vacuum pumps are highly desirable for portable equipment such as medical device/ diagnostic, analytical & gas analyzers.
Pulse Width Modulation (PWM) option is available on certain DC volt version pumps. This unique feature is highly desirable for applications requiring precise control of the pump output.
