diaphragm pump is a perfect match for many applications in the laboratory and procedures since it is oil-free and whisper noiseless, and because it requires so small service. Diaphragms have especially brass worm gear set lengthy lives and hermetically seal the drive space from the pumping chamber to protect mechanical parts from corrosion. The pumps achieve their distinctively high performance from high pumping chamber volume relative to the minimal lifeless space. Highly flexible dual diaphragms with fabric reinforcement ensure 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 contributing to the long assistance intervals having less abrasion also eliminates the majority of the particulate impurities frequently generated inside of scroll or piston pumps. This makes diaphragm pumps the right choice for clean applications.
