Diaphragm Pumps and Compressors for Air, Gases, Liquids and Vapors

The KNF diaphragm pumps are based on a simple principal - an elastic diaphragm, fixed on its edge, moves up and down its central point by means of an eccentric. In this way the medium is transferred using automatic valves.

Due to the KNF modular system, the parts used to transfer the gases can be made from materials with varying degrees of durability. The customer has a choice of pump drives ranging from a selection of motors to explosion-proof models.

These diaphragm pumps offer a high level of performance despite their small size. They are required especially in the fields of analysis, medicine and production technology.

The pumps are used for transferring and drawing gases, taking samples (even liquids in a vacuum, aspiration), evacuating vessels and compressing gases in process systems and vessels.
