TEMPERATURE-RESISTANT AND HEATED DIAPHRAGM GAS SAMPLING PUMPS N 024 ST.11 E with thermostatic temperature control N 036 ST.26 E with electronic temperature control The temperature-resistant and heated 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. Uncontaminated flow of the media (oil-free operation) No maintenance required Diaphragm pumps have become the standard in many analytical applications. Based on their design, they work without any lubrication. No condensation in the pump head Even saturation of heat throughout the pump head Pumps for this new range are available in three different versions: ½ A resistant to temperature version up to 240 °C (.16) ½ A heated version (240 °C) with thermostatic temperature control (.11) ½ A heated version for temperatures up to 240 °C with electronic temperature control (.26) with PC software . Low heat loss to surroundings Easy access to the pump head Energy efficient heating Electronically controlled heating system PC software for controlling the pump via a PC and documentation of all operational data There is a choice of pump drives ranging from a selection of AC motors to explosion-proof models. Please contact us for further details. Often hot gases need to be analysed, and the gas must not be allowed to cool down when it is transferred from the source being checked, to the analyser as the constituent parts could condense out, leading to faulty results. To overcome these problems hot gases are pumped using diaphragm pumps with heated heads. All models are characterised by an even spread of temperature throughout the pump head and highly efficient insulation.

HINTS ON FUNCTION, INSTALLATION AND SERVICE FUNCTION OF KNF DIAPHRAGM VACUUM PUMPS AND COMPRESSORS HINTS ON INSTALLATION AND OPERATION 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. • Range of use: Transfering air and gases The .26...
