Characteristic
Available Models

VACUUBRAND aluminum diaphragm pumps are ideal for many laboratory applications because they are oil-free and very quiet, and because they require so little maintenance. The diaphragms have a particularly long service life and hermetically seal the drive space from the pumping chamber to protect mechanical parts from corrosion. The pumps achieve their distinctly high performance due to the large volume of the pumping chamber relative to the minimal dead space. Highly flexible FKM double diaphragms with fabric reinforcement ensure extremely long diaphragm life. The pumps operate completely oil-free. In normal operation, they are completely free of abrasion. This makes VACUUBRAND diaphragm pumps the right choice for clean applications.
