Atlas Copco vacuum pumps

Thursday, 12 February, 2015

Atlas Copco vacuum pumps support the needs of users across a range of markets, including mining, cement, paper, refineries and food, as well as industries as diverse as aerospace, automotive, refrigeration, glass, bottling, canning and woodworking.

The GHS VSD+ series is a range of efficient, intelligent vacuum pumps with a variable speed drive (VSD). Designed to deliver peak performance at operating pressures found in industrial applications, the series is claimed to offer: energy savings of around 50%; high efficiency to reduce life-cycle costs; better performance against oil-sealed and dry vane vacuum pumps; quiet operation; sustainable productivity; and reduced environmental impact due to ultrahigh oil retention.

The GVD 0.7-28 series small two-stage, oil-sealed rotary vane pumps deliver good ultimate vacuum pressure, high pumping efficiency and good vapour handling capabilities with quiet operation. All pumps/motors are approved to UL and CSA standards and many feature a patented mode selector switch, meaning one model is suitable for both high-vacuum or high-throughput applications.

The GVD 40-275 series two-stage, oil-sealed rotary vane vacuum pumps feature high ultimate vacuum, rapid pumping speeds, quiet operation and the ability to handle water vapour. The direct drive rotary vane pumps are inherently compact and vibration-free. With their finger-proof fan and coupling housings, they offer operator protection.

The ZRS 250-4200 mechanical booster pumps, based on the simple rotary lobe principle, are suitable for applications where high pumping speeds are required for pressures in the region of 0.01 to 50 mbar. The pump must always be backed by another pump, which can deliver against a high-pressure differential to atmospheric pressure. Operating at relatively low pressures, the booster pump is not exposed to the same concentrations of corrosive process media as is the backing pump.

The GLS 250-500 series features an efficient, space-saving design. It has been improved to deliver better dependability and productivity, combined with minimal maintenance and process downtime. This is important in demanding applications such as the automotive and aerospace industries, and their supply chains.

Liquid ring vacuum pumps are offered in a number of configurations, suitable for operation in once through, partial or total recirculation. The AW liquid ring vacuum pumps are available for both single- and two-stage pumps with capacities from 200-37,500 m3/h and vacuum levels down to 30 mbar.
