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

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 an 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.

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 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
