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, 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 favorite 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).
