Typical applications for chemistry diaphragm pumps include evacuating chemically aggressive gases and vapors from such equipment as rotary evaporators, vacuum drying cabinets and centrifugal concentrators. Chemistry diaphragm pumps from VACUUBRAND have uncompromising chemistry designs: Due to fluorocompounds they are very resistant to chemical vapors from inlet to exhaust, and are very tolerant of condensate. Our two-, three- and four-stage pumps also have a gas ballast valve that helps to preserve pump performance when working with condensable vapors. Pumping chambers are hermetically separated from the drive space, ensuring long lifetimes of mechanical parts. Most importantly, diaphragm pumps are oil-free, for vastly reduced service demands compared with oil-sealed pumps. They eliminate the water waste of water-jet aspirators, and the contaminated waste-oil disposal of rotary vane pumps.
