VACUUBRAND' s aluminum design diaphragm pump is a perfect match for many applications in the laboratory and operations because it is oil-free and whisper quiet, and because it requires so little service. Diaphragms have especially long 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 dead space. Highly flexible FPM double diaphragms with fabric reinforcement guarantee an extremely long diaphragm lifetime. 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.

* innovative connections in the new NT models ensure very low leak rates for excellent flow rates under vacuum and long-term performance stability, even after thousands of hours of service.
* no abrasion, making it dust- and contamination-free
* long diaphragm and valve lifetimes: Made of highly flexible FPM, with fabric-reinforced double diaphragms for improved long term stability
* new patented drive support system in NT pump models provide for uniquely quiet, low-vibration operation.
