Diaphragm-Logo.pngair/gas Diaphragm Pumps

The air/gas diaphragm pump provides a pumping chamber which is totally sealed, therefore, does not require a sliding seal between moving parts. Vacuum and pressure are produced by the flexing of the diaphragm back and forth in the chamber. The reciprocating action is created by an eccentric driven connecting rod under the diaphragm. The air/gas diaphragm pumps can handle corrosive gases and vapours when the correct materials are specified and are completely oil free, making them ideal for use in applications where contamination cannot be tolerated.
