Concept Features Areas of use

The Mini Diaphragm VacuumPumps from KNF are based on a simple principal - an elastic dia- phragm, 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.The pumps are equipped with thepatented stress-optimized struc- tured diaphragm, resulting in a high pneumatic performance, a durable product and compact size. Special valves ensure that the product can cope easily with vapour and con- densation.Thanks to the KNF modularsystem, the parts used to transfer the gases can be made from mate- rials with varying degrees of durabi- lity. The pumps can be driven by either AC or DC motors. Uncontaminated flow No contamination of the media due to oil-free operation The Mini Diaphragm Pumps offer a high level of performance despite their small size, as well as an excel- lent price performance ratio. They are required especially in the fields of analysis, medicine, production technology or be used as roughing pump for turbomolecular pumps.The pumps are used for suckinggases, taking samples (even liquids in a vacuum) and evacuating ves- sels and systems.The AC models are suited for use inmachinery which is permanent or mains-operated. Mini Diaphragm Pumps for portable and stand-alone equipment require DC power sup- plies. Maintenance-free Compact size due to structured diaphragm High performance because of structured diaphragm High level of gas tightness Long product life thanks to structured diaphragm Very quiet and little vibration Copes well with vapour and con-densationReady for assembly Can operate in any installed posi-tion
