Edwards, a global manufacturer of vacuum and abatement equipment and services, has extended its range of GXS dry pumps to meet the demands of high volume industrial OEMs and end-users.

The new GXS450 and GXS750 pumps and combinations feature innovative screw technology and a high efficiency drive to deliver vacuum performance.

“We are delighted to introduce the new larger versions to our range of GXS dry pumps,” says Owain Charles, Edwards product manager – GV dry pumps. “At Edwards we have extensive experience of designing pumps for harsh process vacuum applications and now customers requiring higher pumping capacity can realise the full benefits of our intelligent screw technology.”

The units offer pumping speeds of up to 740m3h-1, and when combined with a booster pump can offer even higher speeds of up to 3360m3h-1, while achieving vacuum typically down to 5x10-4 mbar without purge.

According to Edwards, the pumps are suited to many applications which require rapid pumping of large gas volumes. For example, steel degassing and metallurgy processes, glass coating, solar coating, LED manufacture and load-lock applications for vacuum chamber evacuation.

The pumps are an extension of the existing GXS range, which promises reliable operation in harsh applications, and the new variants feature all the same benefits as the smaller versions.

The GXS has a five year service life while the pump mechanism can be cleaned easily using the high flow purge and solvent flush accessory, which removes the need to partially strip the pump.

In addition, the device enables users to minimise their environmental impact as it reduces gas and power consumption. The motor is matched to the inverter to give up to 15% efficiency improvement compared to current designs, which further reduces the cost of ownership.
