diaphragm pump is a perfect match for many applications in the laboratory and functions since it is oil-free and whisper quiet, and because it requires so little service. Diaphragms have especially long lives and hermetically seal the drive space from the pumping chamber to protect mechanical parts from corrosion. The pumps obtain their distinctively high performance from high pumping chamber quantity in accordance with the minimal lifeless space. Highly flexible double diaphragms with fabric reinforcement make sure an extremely long diaphragm lifetime. The pumps operate definitely oil free , nor have any sliding elements in the gas path. In normal operation they are completely free of abrasion. Besides adding to the long Diaphragm Vacuum Pump service intervals the lack of abrasion also eliminates most of the particulate impurities regularly generated inside of scroll or piston pumps. This makes diaphragm pumps the right choice for clean applications.
