    Miniature Diaphragm Pump Compressor, Max. Flow Rate 12 L/min & 22InHg,  Brushless DC Motor Miniature Diaphragm Pump Compressor, Max. Flow Rate 12 L/min & 22InHg,  Brushless DC Motor Miniature Diaphragm Pump Compressor, Max. Flow Rate 12 L/min & 22InHg,  Brushless DC Motor

This miniature diaphragm pump is based on a DC motor that drives a connecting rod to oscillate an elastic membrane, resulting in pumping action. During the downward stroke, the diaphragm draws the medium in via the inlet valve while pushing the medium out via the outlet valve. The diaphragm hermetically seals the compressible chamber during the pumping process.   Both DC brush or brushless motor options are available.  Single head or double heads options are available to meet high pressure or flow requirements.
