DESCRIPTION
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)

TECHNICAL DATA
Chemistry diaphragm pumps, chemistry vacuum systems and chemistry pumping units
Our chemistry diaphragm pumps are available in a full range of volume flow rates and ultimate vacuum options. Single-stage models reach as much as 70 mbar (absolute) vacuum. Connecting pump heads in series as two-, three- or four-stage pumps improves the ultimate vacuum to as much as 0.6 mbar. Connecting heads in parallel provides higher flow rates. Our line offers combinations that satisfy virtually any laboratory need.
Nomenclature for VACUUBRAND pumps is built from the following codes designating specific features or components:
M = diaphragm (membrane) pump
E, Z, D, V = number of pump stages E = single stage, up to 70 mbar Z = two stages, up to 7 mbar D = three stages, up to 1.5 mbar V = four stage, up to 0.6 mbar
C = chemistry design, with fluoropolymer flowpath
NT = labels the new series of pumps comprising the New Technology
AK = separator catchpot for inlet or outlet condensates, collects particles and droplets, keeps condensate in vacuum line from flowing into the pump, protecting pump performance and providing additional noise reduction on the pressure side EK = exhaust vapor (emission) condenser for nearly 100% solvent recovery in compact design, protecting environment and lab air
TE = dry ice or water ice cooled emission condenser for solvent recovery
PC = "Pumping Unit, Chemistry" - a chemistry pump with vacuum control and solvent recovery
Chemistry vacuum system = a chemistry pump with accessories like inlet catchpot and/or solvent recovery
Chemistry pumping unit = a chemistry vacuum system with vacuum control and solvent recovery
SYNCHRO = pumping unit for simultaneous operation of two independent vacuum applications by a single pump
