Edwards Turbomolecular pump model: Next240 II T Horizontal**This unit looks like a new pump.Has slight cosmetic blemishes from normal use. See photos for further details.The nEXT is a hybrid bearing compound turbomolecular pump. nEXT pumps combine our proven bearing technology (oil lubricated ceramic lower bearing with dry permanent magnetic upper bearing), an improved rotor design with a new molecular drag stage to deliver improved pumping speed and compression ratios, and user serviceability. They feature 24 V to 48 V DC sensor less motors with a built-in drive that is fully compatible with our range of TAG and TIC controllers.nEXT turbomolecular pumps are hybrid bearing pumps with integrated controllers for pumping speeds from 47 to 1250 ls-1.FeaturesUpper magnetic bearing - ensures clean vacuum, low power and low vibration.Optimized rotor designs - deliver high speeds and high compression.Range of variants suitable for many applications - D = standard nEXT pump variant, H = optimized rotor design for high light gas compression and T = additional regenerative stage for increased compression and higher backing pressure capabilityIntegrated controller / electronics - offers direct I/O or serial control or can be connected to one of our TAG or TIC controllers for easy systemization.Fully user serviceable - oil cartridge and bearings can be changed in the field with minimal tooling.Inlet screen - supplied as standardSpecificationsParameter ValuePower Total Rated 160.00 WPumping Speed Nominal 1439.99 l/minPressure Ultimate 3.750 10 TorrPressure Backing Max. 15.00 TorrRotational Speed Nominal 1000.00 HzRamp Up Time 150.00 sCompression Ratio N 21.000 10Compression Ratio He 1.000 10Compression Ratio H 215000.00Pumping Speed Helium Nominal 1379.99 l/minPumping Speed H2 Nominal 989.99 l/minflow Volume Gas Ballast Purge 0.045 Pam/sAdditional Prep Fees May Apply
