Edwards EXT75DX Compound Turbomolecular Vacuum Pump - NEW

The EXT75DX is a hybrid bearing compound turbo pump that combines the proven technology of a ceramic mechanical lower bearing, a dry permanent magnetic upper bearing and Holweck drag stage with the added convenience of an on-board 24V controller allowing parallel and serial communication compatible with our TAG and TIC controllers. It is available with either aDN40NW, ISO63, DN63CF or an ISO100 inlet flange with an N2 pumping speed of up to 66ls-1. A basic pump system would require an EXT75DX pump, a TAG or TIC controller, either an air or water cooling accessory and a suitable backing pump.

  • Compatible with TIC turbo and instrument controller
  • Multiple communication modes available including parallel mode, which allows traditional control signal interface and serial mode, which allows RS232 interface
  • Numerous user configurable parameters via RS232 interface including vent valve control settings, normal speed indication, stand-by running speed, programmable power settings, power consumption and pump temperature.
  • Enhanced monitoring capability including pump speed, power and temperature.
