Atlas Copco to launch VSD vacuum pump range at ComVac 2015

The GHS 350-900 VSD+ range, generating nominal displacement of up to 900m3/h, incorporates state-of-the-art variable speed drive technology, which enables vacuum generation to adapt precisely to the user's requirements as part of a central supply system. Coupled with an innovative motor design, the new range sets new standards for energy efficiency of vacuum pumps, resulting in a dramatic reduction in the total cost of ownership.

Benchmarked against oil-sealed and dry vane vacuum pumps, the GHS VSD+ pumps offer improved performance and a 50 per cent reduction in noise levels.

Also on show at ComVac will be a prototype of the new GHS 1900 VSD+ vacuum pump, offering nominal displacement of 1900m3/h, which will soon be added to the vacuum range.

Based on the well-known and durable plug-and-play design principles of Atlas Copco compressors, these vacuum pumps have been designed by vacuum engineers to deliver peak performance at operating pressures commonly found in industrial applications. The new GHS-VSD+ vacuum pumps are visually based on Atlas Copco's well-known compressor design, with all of the components cleanly integrated into a single housing.

The efficiency credentials of the range are evidenced by conformance with ISO 50001 and 14001 standards, while environmental impact is reduced as a result of impeccable oil retention at all operating pressures.

Fully wired, complete systems

Christoph Angenendt, Communication Manager of the Atlas Copco Utility Vacuum Business Unit, says: "The level of efficiency achieved with this new range is a product of innovative design and variable speed control. From a technology and design viewpoint, the new vacuum pumps are based on Atlas Copco compressors, and therefore provide fully wired, complete systems in a single housing. Compared to oil-sealed and dry-valve vacuum pumps, the new range provides noticeably greater performance and these pumps are considerably quieter than comparable machines."

Atlas Copco's GHS VSD+ series is the latest addition to the company's state-of-the-art range of vacuum products for a wide array of industry sectors including cement and paper plants, mining and refineries, food processing and packaging, aviation and space travel, automotive manufacturing and wood processing.

The GVD 0.7-28 series of small two-stage oil-sealed rotary vane pumps delivers excellent ultimate vacuum pressure, high pumping efficiency and superior vapour-handling capabilities with quiet operation. These pumps offer a reliable and stable performance that set the industry standard for R&D and scientific pumping applications.

Atlas Copco's GVD 40-275 series of two-stage oil sealed rotary vane vacuum pumps are renowned for their high ultimate vacuum, rapid pumping speeds, quiet operation and the ability to handle water vapour. These direct drive rotary vane pumps are inherently compact and vibration free, and with their finger-proof fan and coupling housings they offer excellent operator protection.

The ZRS 250-4200 mechanical booster pumps, based on the simple rotary lobe principle, remain the favourite pump for applications where high pumping speeds are required for pressures in the region of 0.01 to 50mbar. This 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 mechanical booster pump is not exposed to the same concentrations of corrosive process media as is the backing pump, which makes it highly reliable.

Better dependability and productivity

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 industry's most efficient, space-saving design. The GLS has been improved, upgraded and fine-tuned to deliver even better dependability and productivity combined with minimal maintenance and process downtime. This is crucial in demanding applications such as the automotive industry, aerospace sector and their supply chains.

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 200-37,500 m ³/h and vacuum levels down to 30mbar (a).
