STP Series

The STP magnetically levitated turbomolecular pumps are the first choice for high-up time, hydrocarbon free pumping. The multi-axis magnetic bearing system is used to suspend the rotor during operation, ensuring there is no risk of contamination while minimizing vibration, noise and maintenance requirements. The STP pumps can be fully interfaced with advanced controllers to operate on a wide range of applications and processes. The first STP pumps were sold in 1983 and there are now over 70000 installations worldwide.

EXT Series

Capacity: 42 l/s - 540 l/s

Edwards EXT Turbo pumps use a hybrid bearing arrangement with a permanent magnet upper bearing and an oil lubricated ceramic lower bearing. The EXT range uses two basic technologies: (i) conventional full stack turbomolecular and (ii) compound molecular. EXT pumps use monobloc rotors machined from solid bar by computer controlled high speed milling machines. This technology produces stable, rigid rotors and allows virtually unlimited design flexibility for optimum vacuum performance.

nEXT Series

Capacity: 240 l/s - 400 l/s

Built on over two decades of experience based on Edwards tried and trusted EXT and STP ranges, nEXT sets the new benchmark for scientific turbopumps. nEXT combines all the latest technological advances in turbomolecular pumps with end-user serviceability. Conventional turbopump rotors deliver either high speed or high compression. The nEXT delivers both. The Edwards nEXT pumps are truly end user serviceable in just minutes…you can do it.
