Next Turbo pumps

Pumping speed from 85 to 900 l/s.

The nEXT pumps offer superior performance, reliability and end user serviceablity, setting the benchmark for scientific turbomolecular pumps. Performance is assured with the nEXT family of turbomolecular pumps which now includes the new 730 l/s and 930 l/s variants, providing fast pump down and improved cycle times with reduced operational pressures. When looking for a turbomolecular pump with outstanding compression ratios look no further than the Edwards nEXT, the cost-efficient pumping package enables low ultimate pressure to be achieved making them suitable for a range of coating and light industrial applications. For scientific OEM customers who are already benefitting from the range of bespoke and tailored nEXT solutions, similar solutions based on these larger pumps are now available. These include multi inlet splitflow pumps and cartridge pumps. Now larger instruments can benefit from higher pumping speeds, and existing configurations could run on a reduced pump count.

Superior performance

Exceptional pumping speeds and compression ratios

Superior reliability

Built on decades of experience and based on our tried and trusted EXT and STP ranges

4-year maintenance

Up to 4 years between pump service

100% User-serviceable

Quick and low-cost oil lubrication cartridge and full bearing change

Hybrid Bearing Technology

Ceramic lower bearing and dry permanent magnet upper bearing

Edwards nEXT sizes

nEXT turbomolecular pumps are hybrid bearing pumps with a compound drag stage and integrated controllers for pumping speeds from 47 to 400 l/s. They all feature a permanent magnetic upper bearing, which eliminates hydrocarbons at the top of the rotor and an oil lubricated lower bearing for reliable high speed operation.

The on-board controller interfaces directly with our TIC and TAG controllers to provide low cost system integration. The nEXT models also allow user serviceability by way of a user changeable bearing cartridge for low cost of ownership.

Product Features

MULTIPLE DRAG STAGES

for higher compression ratios and geater backing pressure tolerance

PERMANENT MAGNET UPPER BEARING

for a hydrocarbon free vacuum, reduced vibration and minimum wear

SENSORLESS DRIVE

for high efficiency and compactness with reduced stray magnetic fields

VENTING

Manual vent port with automatic valve accessories for rapid venting and quick cycle times

PATENTED BEARING SUSPENSION

system that minimises noise and vibration transmitted to the vacuum system

FLEXIBLE CONTROL

simple parallel operation, sophisticated serial control, wide operating voltage range from 24V to 48V d.c.

Edwards nEXT730 and nEXT930 turbomolecular pumps are the latest addition to the Edwards nEXT family, offering class leading performance along with high reliability and low cost of ownership. With over 80,000 tried and trusted nEXT pumps produced we are now bringing higher pumping speeds and increased flexibility to new, more demanding sectors and applications. These new models extend nEXT’s capability with inlet flange options of ISO / CF 160 and ISO / CF 200, giving pumping speeds of over 900 l/s.

    Features and benefits

  • Class leading pumping speeds over 900 l/s
  • Broad range of applications including new applications for nEXT
  • End user service capability including end user bearing change
  • Ease of installation and integration
