Screw Vacuum Pumps Require Low Maintenance

Edwards has launched  a new range of dry pumps that are designed to deliver high vacuum performance and enable full process integration. The compact GXS pump features screw technology that can help users optimize their processes, resulting in a low cost of ownership and a reduced footprint.

The GXS has a pump service life of up to five years and requires low maintenance, even in harsh applications. The pump mechanism can be cleaned using the high-flow purge and solvent flush accessory, which removes the need to partially strip the pump. This also can decrease downtime associated with using alternative products that require manual cleaning.

The pump provides vacuum down to 1x10-3 mbar (7.5x10-4 Torr). This is ideal for a variety of applications from light duty 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 GXS pump has reduced gas and power consumption. The motor is matched to the inverter to give up to 15 percent efficiency improvement. All pumps are fitted with a controller as standard, providing users with reduced installation cost and enhanced control features, including standby 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.
