Edwards GXS750 – dry screw vacuum pump

The GXS series combines its own screw technology with high-efficiency drives and advanced temperature control. The GXS750 reaches 740 m³/h and an ultimate pressure below 0.01 mbar; it can be operated continuously up to atmospheric pressure. The motor power is 22 kW pump.

Features

  • Shafts supported at both ends (no overhung bearings) for very low vibration and reliable starting even in harsh processes
  • High-efficiency motors with electronic drives for high torque in difficult processes
  • Good powder tolerance; extensive accessories such as inlet filters, automatic inlet isolation valves and silencers
  • Purge gas packages Light Duty, Medium Duty and Medium Duty+ depending on the process

Typical applications

Edwards names, among others, metallurgy (vacuum brazing, electron beam welding, nitriding, low-pressure carburising, sintering, metal injection moulding, investment casting), coating and chemical processes.

Versions of the Edwards GXS750

The 12 versions differ in the mains voltage (LV 200–230 V, HV 380–460 V), the purge gas package (LD, MD, MD+) and the installation (outlet at the side on skids or at the rear on castors); in addition there is an ATEX version (category 3, T2). The gas load and the purge gas quantities for each package are given in the Edwards operating instructions. According to Edwards, the MD and MD+ versions of this size need the optional Pump Display Terminal (PDT) for operation.
