DIAPHRAGM GAS SAMPLING PUMPS IN ATEX Diaphragm pump N 0150 ST.9E Ex - for use in potentially explosive atmospheres The Diaphragm Vacuum Pumps from KNF 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. Pure transfer, evacuation and compression of air, gases and vapours No contamination of the media due to oil-free operation The Diaphragm Vacuum Pumps offer a high level of performance despite their compact size, as well as an excellent price performance ratio. They are required especially in the potentially explosive fields of chemical, analysis, energy and production technology. The KNF modular system permits selection of materials with various levels of gas resistance for parts in contact with gas; the pump drive is available in a variety of voltages and frequencies. Please contact us! High level of gas tightness: approx. 6 x 10-3 mbar x l/s Pumps and pump drives in this product series are explosion proof according to 94/9/EC (ATEX). Cool running motor even when in constant use Explosion protected to ATEX Corrosion resistant models The pumps are used for transferring, compressing and sucking air, gases and vapours, taking samples (even transferring liquids using a vacuum) and evacuating and compressing vessels etc. Long product life Very quiet and little vibration Can operate in any installed position PERFORMANCE DATA Type Delivery (l/min)* Vacuum (mbar absolute)

TECHNICAL INFORMATIONS DIAPHRAGM PUMPS CONFORMING TO 94/9/EC (ATEX): FOR USE IN POTENTIALLY EXPLOSIVE ATMOSPHERES. ATEX - The new standard for explosion protection As part of the new single market, the regulations on explosion prevention and protection have now been unified throughout Europe. The legal requirements are set out in the directive 94/9/EC (also known as ATEX). In Germany, the directive was passed into national law on March 1st,1996. Compared to the previous legal requirement, the scope of the regulations have now been extended: whereas the old regulations were concerned with...

HINTS ON FUNCTION, INSTALLATION AND SERVICE FUNCTION OF KNF DIAPHRAGM VACUUM PUMPS AND COMPRESSORS HINTS ON INSTALLATION AND OPERATION MODEL CODE FOR EASY ORDERING An elastic diaphragm is moved up and down by an eccentric (see illustration). On the down-stroke it draws the air or gas being handled through the inlet valve. On the up-stroke the diaphragm forces the medium through the exhaust valve and out of the head. The compression chamber is hermetically separated from the drive mechanism by the diaphragm. The pumps transfer, evacuate and compress completely oil-free. gases at temperatures...
