1 DIAPHRAGM VACUUM PUMPS AND COMPRESSORS N26.1, N26.2, N26.3 N 26.1 ANE Concept 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. 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 to explosion-proof models. Please contact us for further details Features Pure transfer, evacuation and compression of air, gases and vapours No contamination of the media due to oil-free operation Maintenance-free Corrosion resistant models High level of gas tightness: approx. 6 x 1-3 x l/s (not tested in serial production) Long product life Very quiet and little vibration Cool running motor even when in constant use Ready for assembly Can operate in any installed position Areas of use The Diaphragm Vacuum Pumps offer a high level of performance despite their small size, as well as an excellent price performance ratio. They are required especially in the fields of analysis, medicine and production technology. The pumps are used for transfering, compressing and sucking air, gases and vapours, taking samples (even liquids in a vacuum) and evacuating and compressing vessels. Type Delivery Vacuum atm.

4 HINTS ON FUNCTION, INSTALLATION AND SERVICE FUNCTION OF KNF DIAPHRAGM VACUUM PUMPS AND COM- PRESSORS 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. Diaphragm pump HINTS ON INSTALLATION AND OPERATION Range of use: Transferring air and gases at temperatures between +5 C and +4 C Permissible ambient temperature: between +5 C and +4 C 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 pressure or vacuum; when a pump is switched on the pressure in the suction and pressure lines must be atmospheric. Pumps that start against pressure or vacuum are available on request To prevent the maximum operating pressure being exceeded, restriction or regulation of the air flow 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 the fan can draw in sufficient cooling air 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. MODEL CODE FOR EASY ORDERING The model code is identical to the order number. It is made up as follows: N 26.1 AN E Base model Head connections Head materials OEM version with ac motor Other motor data eg.: In addition the motor data must be given in the purchase order (voltage, frequency, and protection class). In our extensive program you are sure to find the pump you need for your particular application. TECHNICAL DETAILS 23 V/5 Hz, IP Maximum permissible gas and ambient temperature: between +5 C and +4 C. Option N 26.9 Pump head guaranteed gas-tight: leakage rate less than 6 x 1-3 x l/s in the material combinations AN, AV, SN, SV, ST. Head connections Heads with suction side in parallel Heads with pressure side in parallel Heads in series HINTS ON SERVICE The diaphragm and valves are the only parts of the KNF diaphragm pumps subject to wear. They are easy to change, as no special tools are needed. If you have any questions, please call our application engineers (see below for contact telephone number).
