DIAPHRAGM VACUUM PUMPS AND COMPRESSORS DATASHEET N 2400 N 2400.15 ST.9 E Concept The diaphragm pumps from KNF arebased on a simple principle an elastic diaphragm, ixed 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. Thanks 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 models. Please contact us for further details. Features Pure transfer No contamination of the media due to oil-free operation Maintenance-free Corrosion resistant models High level of gas tightness Following leakage rates are available:.9 corresponds to < 6 x 10-3 mbar l/s SP.13 corresponds to < 6 x 10-6 mbar l/s ST.13 corresponds to < 6 x 10-5 mbar l/s Long product life Cool running motor even when in constant use Areas of use These pumps are required especially in the fields of analytical technology, chemistry industry and production technology as well as research. The pumps transfer, compress or draw highly aggressive gases and vapors, take samples as sample gas pumps (or liquid samples using vacuum), evacuate vessels or transfer aggressive gases as process gas pumps in chemical facilities.

HINTS ON FUNCTION AND INSTALLATION Function of KNF diaphragm gas sampling pumps 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. Hints on installation and operation Range of use: Transferring air and gases at temperatures between +5 C and +40 C. Permissible ambient temperature: between +5 C and +40 C. Please check the compatibility of the materials of the pump head, diaphragm and valves with the medium. The KNF product line contains pumps suitable for pumping aggressive gases and vapors please contact us. The standard pumps are not suitable for use in areas where there is a risk of explosion. In these cases there are other products in the KNF program please ask us for details. The pumps are not designed to start against or vacuum; when a pump is switched on the in the suction and lines must be atmospheric. Pumps that start against or vacuum are available on request. To prevent the maximum operating being exceeded, restriction or regulation of the air low should only be carried out in the suction line. Components connected to the pump must be designed to withstand the pneumatic performance of the pump. Install the pump so that suficient supply of cooling air is ensured. Fit the pump at the highest point in the system, so that condensate cannot collect in the head of the pump that prolongs working-life. KNF reserves the right to make technical changes.
