diaphragm pump is an ideal match for many applications in the laboratory and functions since it is oil-totally free and whisper calm, and because it requires so little service. Diaphragms have specifically long lives and hermetically seal the drive space from the pumping chamber to protect mechanical parts from brass worm gear set corrosion. The pumps achieve their distinctively powerful from high pumping chamber quantity relative to the minimal lifeless space. Highly flexible dual diaphragms with fabric reinforcement assure an extremely long diaphragm life time. The pumps operate totally oil free and do not have any sliding components in the gas path. In normal operation they are free of abrasion. Besides adding to the long provider intervals the lack of abrasion 
also eliminates most of the particulate impurities regularly generated inside of scroll or piston pumps. This makes diaphragm pumps a good choice for clean applications.
