Edwards nEXT Turbo Molecular Pumps 

Overview

A turbo molecular pump is a multistage axial-flow turbine in which high speed rotating blades provide compression by increasing the probability of gas moving in the pumping direction. The turbo molecular pump is optimized for molecular flow conditions and requires a suitably sized backing pump to exhaust to atmosphere. The Edwards nEXT series of turbo pumps have been designed to combine all the latest technological advances in turbo molecular pumps providing end-user serviceability and delivering a truly class leading product. Pump sizes available offering true 85, 240, 300, 400 and we have now added 700 and 900 liters per second pumping speed performance to our nEXT family(N2).

The pump has been totally re-designed to optimize performance and achieve both greater speeds and higher compressions, while maintaining increased levels of reliability in a small package.  

 • Class leading performance in a reduced footprint
•  Enhanced customer choice with standard and compression focused variants
•  Increased operating envelope maximized by Edwards’ patented direct impeller temperature measurement technology
•  Additional flexibility from customized interstage and backing port position selection
•  4 year service with full end-user field serviceability
•  CMSD enabled low vibration levels
•  Intelligent pumps with included micro USB port and Edwards nST software allowing pump monitoring, control and configuration

nEXT 85 Turbo Molecular Pump

nXDS10i cq5dam.web.600.600The nEXT 85 pumps consist of the turbo molecular pump with a permanently attached controller containing drive electronics and comes configured with two different variants, the "D" and "H". The "D" variant incorporates both turbo molecular and drag stages for improved tolerance to higher backing line pressures.The High Compression -"H" variant employs the same technology as the 'D' variant, but is tuned to deliver higher compression. The controller controls the electrical supply to the pump with the exception of standby speed control. It has no manual controls and can only be operated through the logic interface. To operate the nEXT-85  pump you must connect it to your own control equipment and power supply or alternatively use the Edwards TIC Turbo Instrument Controller or TIC Turbo Controller. nEXT 85 pumps are supplied with an inlet-screen fitted into the centering O-ring for ISO version pumps and into envelope for CF version pumps. nEXT85 pumps with an NW 25 interstage-port are supplied with an inlet-strainer that fits into the interstage-port. The inlet-screen and inlet-strainer protect the pump against damage that would be caused by debris entering the pump. The nEXT 85 pumps have a vent-port for venting the pump and vacuum system to atmospheric pressure. The pump is supplied with a manual vent-valve fitted; this can be replaced with a TAV5 or TAV6 solenoid-operated vent-valve.   Edwards nEXT Brochure

nEXT 240 Turbo Molecular Pump

nXDS10i cq5dam.web.600.600

The Edwards  nEXT240D and nEXT240T  turbo molecular pumps  consist of a turbo molecular pump with a permanently attached controller containing drive electronics. The controller controls the electrical supply to the pump with the exception of standby speed control. The Edwards nEXT 240 is a hybrid bearing compound turbo molecular pump. They feature 24 V to 48 V d.c. sensor less motors with a built-in drive that is fully compatible with Edwards range of TAG and TIC controllers. They are available preset for either 80 W or 160 W maximum power, the former enabling use with our 100 W TIC controllers are also recommended for pumping Argon, but with a longer ramp time to full operating speed. The duplex “D” variants have both turbo molecular and drag stages for improved tolerance to higher backing line pressures. The triplex “T” variants feature turbo molecular, drag and Edwards unique fluid dynamic stages for the ultimate in compression ratio and boost technology for maximum vacuum system rationalization. A basic pump system would require a Edwards nEXT240D pump, a TAG or TIC controller, either an air or water cooling accessory and a suitable backing roughing pump. The  “Accessories” for the nEXT 240 are listed below

nEXT 300 Turbo Molecular Pump

nXDS10i cq5dam.web.600.600The Edwards  nEXT300D and nEXT300T  turbo molecular pumps  consist of a turbo molecular pump with a permanently attached controller containing drive electronics. The controller controls the electrical supply to the pump with the exception of standby speed control. It has no manual controls and can only be operated through the logic interface. To operate the nEXT 300 pump you must connect it to your own control equipment and power supply or alternatively use the Edwards TIC Turbo Instrument Controller or TIC Turbo Controller. The 'D' or 'Duplex' variant  has turbo molecular blades and a drag mechanism that allows operation at higher backing pressures than the pure turbo molecular pumps. The 'T' or 'Triplex' variant has turbo molecular blades, a drag mechanism and a regenerative mechanism. The regenerative stage gives the option to utilize 'boost' mode The New Edwards nEXT300 pumps are supplied with an inlet-screen fitted into the centering O-ring for ISO version pumps and into envelope for CF version pumps. nEXT300D pumps with an NW 25 interstage-port are supplied with an inlet-strainer that fits into the interstage-port. The inlet-screen and inlet-strainer protect the pump against damage that would be caused by debris entering the pump. Not included with refurbished pump.The Edwards Turbo pump is supplied with a manual vent-vavle fitted; this can be replaced with a TAV5 or TAV6 solenoid-operated vent-valve. The TAV valve can be directly controlled by the on-board controller. The nEXT pumps have a purge-port: an inert purge gas can be introduced to protect the bearing and motor from corrosion. An optional vent-port adapter and purge restrictor can be fitted to the purge-port to control the flow rate of the purge gas and to filter the gas supply. Air cooling and a water-cooling block are available.
