This micro diaphragm pump (SX-5) 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.  This pump is designed for applications requiring miniaturized size, low power consumption and light weight.
