diaphragm pump is an ideal match for many applications in the laboratory and procedures since it is oil-free and whisper quiet, and since it requires so little service. Diaphragms have especially lengthy lives and hermetically seal the drive space from the pumping chamber to protect mechanical parts from corrosion. The pumps attain their distinctively high performance from high pumping chamber volume in accordance with the minimal dead space. Highly flexible dual diaphragms with fabric reinforcement guarantee an exceptionally long diaphragm life time. The pumps operate completely oil free , nor have any sliding components in the gas route. In normal procedure they are completely free of abrasion. Besides contributing to the long program intervals the lack of abrasion also eliminates the majority of the brass worm gear set particulate impurities frequently generated within scroll or piston pumps. This makes diaphragm pumps the right choice for clean applications.
