Vacuubrand Diaphagm pumps
Chemistry diaphragm pumps and -pumping systems
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 feature uncompromising chemistry designs. Their construction with fluoropolymers makes them very resistant to chemical vapors from inlet to exhaust and very tolerant to condensates. Our two-, three- and four-stage pumps also have a gas ballast valve that provides continuous purge with minimal impact on ultimate vacuum when working with condensable vapors. Pumping chambers are hermetically separated from the drive system 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 cost of water and its contamination well-known from water-jet aspirators, and the waste-oil disposal of rotary vane pumps.
- PTFE sandwich diaphragms and valves made of perfluoro elastomer or PTFE
- internal tubing and fittings made of PTFE/ETFE/ECTFE compounds
- exceptional diaphragm lifetimes with ultra-durable PTFE sandwich design
- head cover and clamping disc made of fluoro compounds with stability core for unsurpassed long-term performance
- very long service intervals for low lifetime cost-of-ownership
- patented new drive system for extra quiet, ultra-low-vibration operation (NT)
- patented new valve mounting system to simplify service access (NT)
- smooth surfaces for easy cleaning (NT)
- new sealing system provides reduced leakage rates for improved ultimate vacuum (NT)
