Edwards EXT75DX Compound Turbo Vacuum Pump - NEW
This model is pinked-out on our site since we may not be able to get NEW from the OEM any longer.
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 a DN 40 NW, ISO-63, DN 63 CF or an ISO-100 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.
