Atlas Copco Adds VSD+ Technology to Vacuum Solutions Portfolio

March 24, 2015

  Atlas Copco has extended its vacuum solutions product line for rough and medium vacuum applications to include a new range of highly efficient vacuum pumps with variable speed drive (VSD) technology. The new range reduces energy usage by up to 50 percent with significantly better performance benchmarked against traditional oil-sealed and dry vane vacuum pumps. The GHS VSD+ features low noise levels and reduced environmental impact due to ultra-high oil retention at all operating pressures.

  “The new GHS VSD+ series’ performance is the latest in pioneering technology advancements in the vacuum industry,” said Jerry Geenen, regional business line manager, vacuum solutions North America, Atlas Copco Compressors. “Our vacuum engineers designed the new series based on well known and durable plug-and-play design principals of our compressors to deliver peak performance at operating vacuum levels commonly found in industrial vacuum applications.”

  The GHS VSD+ range complements Atlas Copco’s full vacuum solutions line, which includes single-stage oil-sealed rotary vane vacuum pumps and systems, fixed-speed oil-injected rotary screw vacuum systems, and new ranges of two-stage oil-sealed rotary vane vacuum pumps, vacuum booster pumps, piston pumps, liquid ring pumps and steam ejectors.

  · The GVS 20-300 series operates according to the proven oil-sealed rotary vane principal that has been successfully used for many years in all general vacuum applications of industry. The GVS 20-300 series ensures the highest possible performance at the lowest possible lifecycle cost. A built-in gas ballast valve is a standard fitting to assist in water handling capability.

  · The GHS 630-4800 series combines a technologically advanced fixed speed screw design with robust oil-sealed rotary technology. All GHS 630-4800 vacuum packages are fitted with a vacuum control valve at the pump inlet; the control valve matches delivered capacity to actual demand, provides minimal fluctuations in vacuum level and reduces wear and maintenance as a result of fewer stop/starts.

  · The GVD 0.7-28 series of small, two-stage oil-sealed rotary vane pumps deliver ultimate vacuum pressure, high pumping efficiency and superior vapor-handling capabilities with quiet operation. These pumps offer reliable performance that set the industry standard for research and development and scientific pumping applications. All pumps and motors in this series are also approved to UL and CSA standards; the patented mode selector switch makes the GVD 0.7-28 suitable for both high vacuum or high throughput applications.

  · The GVD 40-275 series of two-stage oil-sealed rotary vane vacuum pumps offer high ultimate vacuum, rapid pumping speeds, quiet operation and the ability to handle water vapor. These direct drive rotary vane pumps are compact and vibration-free. Finger-proof fans and coupling housings offer excellent operator protection. A comprehensive range of accessories enables use of the GVD 40-275 in a wide variety of vacuum applications.

  · The ZRS 250-4200 mechanical booster pump is based on a simple rotary lobe principle and is ideal for applications requiring high pumping speeds for pressures from 0.01 to 50 mbar. The booster pump must always be backed by another pump to deliver against a high-pressure differential to atmospheric pressure. Because it operates at relatively low pressure and is not exposed to a high amount of corrosive process media, the booster pump is also highly reliable.

  · With over 10,000 units sold, the Atlas Copco GLS 250-500 series of rotary piston pumps sets the standard for performance and reliability as the vacuum industry’s most efficient and space-saving design. The GLS series has been upgraded to deliver even better reliability and productivity with minimal maintenance and process downtime—crucial for demanding applications that serve the automotive or aerospace industry.

  · Atlas Copco liquid ring vacuum pumps are offered as standard packages 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- (AWS) and two-stage pumps (AWD) with capacities from 200-37500 m³/h and vacuum levels down to 30 mbar (a).
