Presentation

The EXT556H incorporates our hybrid bearing and enhanced molecular drag pumping technologies with turbopump stages on a single rotor. It is an 80V pump and therefore must be used with an EXC300 controller.

The EXC300 is a fully featured controller with a user panel, backing pump relay and bake-out band control. It is rack mountable and can power an air cooler and control a vent valve as well as the turbopump.

A basic pump system would require an EXT556H pump, an EXC300 controller, a pump to controller cable, either an air or water cooler accessory, and a suitable backing pump.

Latest requests

I have a broken Edwards EXT556H DN160CF turbo pump that I would like to repair. In addition, I would like to buy one of the same model, or perhaps a turbo which is compatible with the EXC250E turbo controller, so that it interfaces with my vacuum control system properly. Can you help me with this?
