1 DIAPHRAGM VACUUM PUMPS AND COMPRESSORS DATA SHEET N 816 N 816 KNE (w/ AC motor) N 816 KN.29DC-B-M (w/ standard-life BLDC motor) N 816 KN.29DC-B (w/ long-life, multi-function BLDC motor) Concept The diaphragm pumps from KNF are based on a simple principle 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 structured diaphragm, resulting in a high pneumatic performance, a durable product and compact size. Special valves ensure that the product can cope easily with vapor and condensation. Thanks to the KNF modular system, the parts used to transfer the gases can be made from materials with varying degrees of resistance. The pumps can be driven by either AC or DC motors. Features Uncontaminated flow No contamination of the media due to oil-free operation Maintenance-free Compact size High performance High level of gas tightness Long product life Very quiet and little vibration Copes well with vapor and condensation Cool running motor even when in constant use Ready for assembly/integration into OEM devices 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 and production technology. The pumps are used for drawing gases, taking samples (even liquids in a ) and evacuating vessels. The AC models are suited for use in mains operated machinery or stationary applications. The DC models are suited for both stationary, as well as portable, battery-operated devices.

6 HINTS ON FUNCTION AND INSTALLATION Function of KNF diaphragm 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. Hints on installation and operation Range of use: Transferring air and gases at temperatures between +5 C and +40 C. Please check the compatibility of the materials of the pump head, diaphragm and valves with the medium. Permissible ambient temperature: between +5 C and +40 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 or ; when a pump is switched on the in the suction and lines must be atmospheric. Pumps that start against or are available on request. To prevent the maximum operating 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. KNF Neuberger Inc. 2 Black Forest Road Trenton, NJ Tel.
