Chemistry Diaphragm Pumps
Due to fluorocompounds they are very resistant to chemical vapours from inlet to exhaust and are very tolerant of condensate. The 2-, 3- and 4-stage pumps also have a gas ballast valve that helps to preserve pump performance when working with condensable vapours. Pumping chambers are hermetically separated from the drive space, ensuring long lifetimes of mechanical parts. Diaphragm pumps are oil-free, they eliminate the water waste of water-jet aspirators and the contaminated 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
- High diaphragm lifetimes with ultradurable 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
NT models:
- Patented drive system for extra quiet, ultra-low-vibration operation
- Patented valve mounting system to simplify service access
- Smooth surfaces for easy cleaning
- Sealing system provides reduced leakage rates for improved ultimate vacuum
Typical applications for chemistry diaphragm pumps incl. evacuating chemically aggressive gases and vapours from such equipment as rotary evaporators, vacuum drying cabinets and centrifugal concentrators.
