Atlas Copco expands its vacuum solutions

Atlas Copco has recently introduced a new portfolio of vacuum products which can support the specific vacuum needs of customers across a range of markets, and many common vacuum applications.

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

In early 2015 an innovative, intelligent vacuum pump will be introduced – the GHS VSD+ – representing a real leap forward in the vacuum industry.

The GHS VSD+ Series is a new range of highly efficient, intelligent vacuum pumps with Variable Speed Drive (VSD) from Atlas Copco. 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 GHS VSD+ series offer:

· Energy savings of around 50%
A state-of-the-art technology, variable speed drive (VSD) and innovative motor design combine to produce a leap forward in efficiency to dramatically reduce lifecycle costs

· Significantly better performance against benchmarked oil-sealed and dry vane vacuum pump

· Quiet operation – noise levels are around half that of comparable 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.

Atlas Copco currently offers a range of vacuum solutions:
The GVD 0.7-28 series of small 2-stage oil-sealed rotary vane 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 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 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 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. A comprehensive range of accessories is available to allow use on the widest variety of vacuum applications.

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 50 mbar. 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 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 200-37500 m³/h and vacuum levels down to 30 mbar (a).
