• Miniature Diaphragm Pump ASP-LP180, Max. Flow Rate 240mL/min,  Brushless or Brushed 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.   Brushless or brushed DC motor option is available.  Price break is available for large quantity of order.
