Negative Pressure Diaphragm Vacuum Pump

The negative pressure diaphragm vacuum pump uses an electric motor to drive the elastic diaphragm in reciprocating motion, altering the pump chamber volume to create negative pressure for gas suction. It is used for extracting corrosive gases and gases containing particulate matter, avoiding oil contamination. It operates stably in laboratory applications such as sample filtration, solvent degassing, and printing ink transfer.
Selection
Select the pump's ultimate pressure based on the required vacuum level, and match the pumping speed according to the gas flow rate. For corrosive media, choose a PTFE or fluororubber diaphragm. Opt for an oil-free structure when low noise is required in the environment, and pay attention to heat dissipation performance and maintenance convenience for long-term operation.
