Company Announcement - Atlas Copco Compressor Technique is proud to introduce a new portfolio of vacuum products that can support the specific vacuum needs of customers for many common vacuum applications across a range of market sectors. This pioneering vacuum technology follows hot on the heels of the extended vacuum solutions portfolio for rough and medium vacuum introduced by Atlas Copco in Q2 2014.

In addition to the new range of 2-stage oil-sealed rotary vane vacuum pumps, Atlas Copco also unveiled a new range of mechanical vacuum booster pumps, rotary piston pumps, liquid ring vacuum pumps as well as steam ejectors. This new portfolio can support the mining, cement, paper, refineries and food sectors as well as industries as diverse as aerospace, automotive, refrigeration, glass, bottling, canning and woodworking.

Atlas Copco’s new GHS VSD+ Series is a highly efficient vacuum pump with Variable Speed Drive. 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. “This innovative, intelligent vacuum pump represents a real leap forward in the vacuum industry,” says Charl Ackerman, Business Line Manager for Atlas Copco Compressor Technique’s Industrial Air Division. “Our heavy investment in R&D has resulted in unparalleled world-class vacuum technology designed and engineered with features that deliver significantly higher efficiency and better performance against benchmarked oil-sealed and dry vane vacuum pumps.”

Feature and benefits of the GHS VSD+ Series include:
• Energy savings of around 50%.
The state-of-the-art technology VSD and innovative motor design combination sets a new standard in efficiency and dramatically reduces lifecycle costs.
• Quiet operation – Noise levels are approximately half compared to similar technologies.
• Sustainable productivity due to built-in efficiency. Conforms to energy management and environmental commitments according to ISO 50001/14001.
• Reduced environmental impact due to ultra-high oil retention at all operating pressures – from ultimate pressure to atmospheric pressure.

The GVD 0.7-28 Series of small 2-stage oil-sealed rotary vane vacuum pumps deliver excellent ultimate vacuum pressure, high pumping efficiency and superior vapour handling capabilities with quiet operation. These pumps offer a reliable and stable proven performance that set the industry standard for R&D and scientific pumping applications. All pumps/motors are approved to UL and CSA standards by an external test house and features a patented mode selector switch. “This means that one model is suitable for both high vacuum or high throughput applications,” explains Ackerman.

The GVD 40-275 Series of 2-stage oil sealed rotary vane vacuum pumps are renowned for their high ultimate vacuum, rapid pumping speeds, quiet operation and ability to handle water vapor. These direct drive rotary vane pumps are inherently compact and vibration free; the finger-proof fan and coupling housings offer excellent operator protection. A comprehensive range of accessories further expand the pump’s suitability across a variety of vacuum applications.

The ZRS 250-4200 mechanical booster pumps are based on the simple rotary lobe principle. “It remains the preferred pump for applications where high pumping speeds are required for pressures in the region of 0.01 to 50 mbar,” states Ackerman. 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. With over 10 000 units sold, the Atlas Copco GLS 250-500 Series of rotary piston pumps set 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 or aerospace industry as well as their supply chains.

Atlas Copco liquid ring vacuum pumps are offered as standard packages in a number of configurations and are 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 ranging from 200 – 37 500 m³/h and vacuum levels down to 30 mbar.
