VACUUBRAND diaphragm pumps have an aluminium design that is ideal for a number of laboratory applications and operations.
The pumps achieve their distinctively high performance from high pumping chamber volume relative to the minimal dead space. Highly flexible FPM double diaphragms with fabric reinforcement guarantee an extremely long diaphragm lifetime.
The diaphragms hermetically seal the drive space from the pumping chamber to protect mechanical parts from corrosion.
The pumps operate absolutely oil free and do not have any sliding components on the vapor side; in normal operation they are completely free of abrasion. Besides contributing to the long service intervals, the lack of abrasion also eliminates most of the particulate impurities frequently generated on the vacuum side of scroll or piston pumps.
