1 min read

The pump from Edwards provides faster pump down compared to similar products and gives an ultimate vacuum down to 1x10-3 mbar (7.5x10-4 Torr).  This can improve the performance in a variety of applications from light duty through to load-lock and harsh process.  

The shafts on the GXS are supported at both ends for increased rigidity, resulting in improved dust handling, reduced vibration and noise levels below 64 dB(A).

The pump  motor is matched to the inverter to give up to 15% efficiency improvement compared to current designs.  All pumps are fitted with a controller as standard with control features including stand-by for reduced utility consumption, pressure control and start-up and shutdown routines.  GXS pumps may be linked to customers dedicated process controllers for full system integration.

The efficient GXS pumps are available in four variants, stand-alone GXS160 and GXS250 or as booster combinations GXS160/1750 and GXS250/2600. The pump and booster combinations can be configured for a wide variety of applications including crystal pulling, lamination, coating, metallurgy, pharmaceutical and food process freeze drying, packaging, plasma sterilization, vacuum chamber evacuation and high purity gas cylinder filling.
