Edwards nEXT930D Hybrid Bearing Compound Turbomolecular Vacuum Pump, 925 l/s, 200 ISO-K (NW 200) Inlet, 500 Watts. PN: B8K200D00.

This listing is for the Edwards nEXT-930D hybrid bearing compound turbomolecular vacuum pump, requires nominal 500W power supply at 48 VDC (Edwards EPS 500 power supply-part number P1012352), compatible with TIC or TAG controllers, reduced start up time to full speed (2.5 min.), pumping speed of 925 liters per second (l/s) of nitrogen, ISO-200 inlet flange, ISO KF-25 foreline flange, pump to controller cable (part number P1012349). A basic pump system would require an Edwards nEXT930D pump, a TAG or TIC controller, either an air or water cooling accessory, an EPS 500 power supply, and a suitable backing pump. Ultimate pressure with a 2-stage oil-sealed rotary vane pump is 3×10-8 mbar. The complete specifications and application brochure can be downloaded below.

The Edwards nEXT930D is a hybrid bearing compound turbo pump and is available with either 200 ISO-K or Conflat 10 inch (200 CF) inlet flanges and has a pumping speed of 925 l/s of nitrogen. The nEXT pumps combine Edward’s proven bearing technology (oil lubricated ceramic lower bearing with dry permanent magnetic upper bearing), with improved rotor design and a new molecular drag stage to deliver improved pumping speeds, compression ratios, and true user serviceability. The 930D pumps feature 48 VDC sensor less motors with a built in drive that is fully compatible with the range of TAG and 100W and 200W TIC controllers. They are available pre-set for 500W power consumption (190W minimum, 600W maximum). When set to lower power consumption, the pump will require a longer ramp time to full operating speed.

User Friendly Maintenance Technology
The new Edwards nEXT technology have enabled the pumps to be serviced in the field. An interim oil lubrication change can be performed, where access allows, in-situ, typically in less than 5 minutes with the minimum of specialist tooling. A bearing and oil lubrication service, with minimum disassembly can be performed in less than 10 minutes using basic workshop tools and an Edwards tool kit. The nEXT pumps will advise the user when a service is due and what level of intervention is required. The request for service is by a simple flashing LED sequence on the pumps, and by serial communication notification.
