diaphragm pump is an ideal match for many applications in the laboratory and operations because it is oil-free and whisper noiseless, and because it requires so little service. Diaphragms have especially long lives and hermetically seal the drive space from the pumping chamber to safeguard mechanical parts from Diaphragm Vacuum Pump corrosion. The pumps obtain their distinctively high performance from high pumping chamber volume in accordance with the minimal dead space. Highly flexible double diaphragms with fabric reinforcement assure an extremely long diaphragm lifetime. The pumps operate completely oil free and do not have any sliding components in the gas path. In normal procedure they are free of abrasion. Besides contributing to the long assistance intervals having less abrasion also eliminates the majority of the particulate impurities frequently 
generated inside of scroll or piston pumps. This makes diaphragm pumps the right choice for clean applications.
