diaphragm pump is an ideal match for many applications in the laboratory and procedures since it is oil-free and whisper calm, and because it requires so small service. Diaphragms have specifically lengthy lives and hermetically seal the drive space from the pumping chamber to safeguard mechanical parts from corrosion. The pumps achieve their distinctively powerful from high pumping chamber volume relative to the minimal lifeless space. Highly flexible dual diaphragms with fabric reinforcement ensure an brass worm gear set exceptionally long diaphragm life time. The pumps operate absolutely oil free and do not have any sliding elements in the gas route. In normal operation they are completely free of abrasion. Besides adding to the long service intervals the lack of abrasion also eliminates the majority of the particulate impurities frequently generated within scroll or piston pumps. This makes diaphragm pumps the right choice for clean applications.
