A turbomolecular pump is a multistage arial flow turbine in which high speed rotating blades provide compression by increasing the probability of gas moving in the pumping direction. The turbomolecular pump is optimised for molecular flow conditions and requires a suitably sized backing pump to exhaust to atmosphere. Edwards nEXT is the ultimate experience in turbomolecular pumps nEXT turbomolecular pumps are built on decades of experience and are drawing from our tried and trusted EXT and STP ranges. nEXT pumps offer superior performance, reliability and end user serviceablity, setting the benchmark for scientific turbomolecular pumps. Exceptional pumping speeds and compression ratios, huge install base of turbo pumps, be spoke design service available, integrated intelligent controls, fully end user serviceable, enhanced customer choice.
