1 DIAPHRAGM VACUUM PUMPS ROUGHING PUMPS N ANDCB (with brushless dc motor) N AN.22 E (with dynamic mass balancing ) Concept The Diaphragm 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. The pumps are equipped with the patented 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 condensation. Several different drive motors are available. Please contact us for more information. ATEX versions available upon request. Features Uncontaminated flow No contamination of the media due to oil-free operation 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 condensation Starts against vacuum May be used as roughing pumps for turbomolecular pumps Can operate in any installed position Areas of use The Diaphragm 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, production technology or be used as roughing pump for turbomolecular pumps. The pumps are used for sucking gases, taking samples (even liquids in a vacuum) and evacuating vessels and systems. THE DYNAMIC MASS BALANCING For applications that demand especially smooth running throughout the whole working range of the pump, KNF has developed, and applied for patent protection on, a dynamic mass balancing. It automatically damps out the out-of- balance resulting from gas forces. Type* Delivery atm. Pressure Weight (l/min) (mbar absolute) Press.

5 HINTS ON FUNCTION, INSTALLATION AND SERVICE FUNCTION OF KNF DIAPHRAGM VACUUM PUMPS AND COMPRESSORS 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 쐍 Range of use: Transferring air and gases at temperatures between +5 C and +40 C. 쐍 Permissible ambient temperature: between +5 C and +40 C. 쐍 Please check the compatibility of the materials of the pump head, diaphragm and valves with the medium. 쐍 The KNF product line contains pumps suitable for pumping aggressive gases and vapors - please contact us. 쐍 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. 쐍 The pumps are designed to start against vacuum. Pumps that start against pressure are available on request. 쐍 To prevent the maximum operating pressure being exceeded, restriction or regulation of the gas flow should only be carried out in the suction line. 쐍 Components connected to the pump must be designed to withstand the pneumatic performance of the pump 쐍 Install the pump so that the fan can draw in sufficient cooling air. 쐍 Fit the pump at the highest point in the system, so that condensate cannot collect in the head of the pump. 쐍 For pumps with dynamic mass balancing: the pump must be supported on rubber mounts or springs so that the natural frequency of the system is fei >1.7 Hz. For lower values of fei correct operation of the dynamic mass balancing cannot be guaranteed. 쐍 For pumps with dynamical mass balancing: if the pump is mounted on a platform that is itself a vibrating system, or contains one, care must be taken to ensure that the two systems do not interfere with each other. HINTS ON SERVICE The diaphragm and valve plates 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). KNF - the competent partner for vacuum and compressor technology.
