diaphragm pump is an ideal match for many applications in the laboratory and operations because it is oil-totally free and whisper quiet, and because it requires so little service. Diaphragms have especially long lives and hermetically seal the drive space from the Diaphragm Vacuum Pump pumping chamber to protect mechanical parts from corrosion. The pumps obtain their distinctively powerful from high pumping chamber volume relative to the minimal lifeless space. Highly flexible double diaphragms with fabric reinforcement assure an extremely long diaphragm life time. The pumps operate absolutely oil free and don’t have any sliding components in the gas path. In normal operation they are completely free of abrasion. Besides contributing to the long assistance intervals the lack of abrasion also eliminates most of the particulate impurities regularly generated within scroll or piston pumps. This makes diaphragm pumps a good choice for clean applications.
