Atlas Copco Introduces New GVS A Oil-Sealed Rotary Vane Vacuum Pumps

Atlas Copco is replacing its GVS series of oil-sealed rotary vane vacuum pumps with the completely new series GVS A. These pumps are suitable for both industrial production and research applications. Flow rates range from 11 to 494  cfm. The old GVS pumps only had a flow range from 14 to 215 cfm. Right from the start, two units with significantly higher capacities than in the past have been added to the range (GVS 470 A and GVS 630 A). In addition, from the GVS 60 A upwards, oxygen variants are available.

With their comprehensive accessories, these rotary vane pumps are suitable for packaging, wood processing, rubber, plastics, paper and printing, material handling and other demanding applications. With motor ratings between 1.2 and 25 HP the pumps have an ultimate pressure to 29.9 in-HgV. 


The new GVS A Series have flow rates that range from 11 to 494 cfm, while the old GVS pumps only had a flow range from 14 to 215 cfm.


Cooler, Quieter and More Compact

The new vacuum pumps have been designed to minimize total operating expenses. Compared with the earlier generation, power demand at the same volume flow is about 15 percent lower. In general, the new units are more compact, making them easier to build in machines or install at the workplace. The vacuum pumps feature low vibrations and are about 3 to 5 dB(A) quieter than their predecessors. They operate at the lowest temperatures in the market, a feature protecting the oil consistency and extending its service life as well as maintenance intervals. All in all, wear is reduced by optimized shaft speeds, low operating temperatures and the special design of the new pump. The quantity of oil has been increased, offering clear benefits under arduous operating conditions if the oil gets contaminated by the process. This also increases the intervals between oil changes.

The GVS A pumps are all extremely reliable. Atlas Copco states this is mainly the result of the sturdy design and very good oil retention capacity at all operating pressures. The pumps operate with internal injection channels, reducing the number of gaskets and the amount of external piping required. In total, the number of components has been reduced by 20 percent and the risk of leakage has been further minimized. These design improvements also reduce the risk of failure. In addition, the new GVS A generation can handle higher inlet pressures than other pumps, including the previous GVS series. At coarse pressures, other pumps could be prone to overheating or oil spills. The new GVS A series is therefore suitable for a much wider range of applications than its predecessor.


Protection Against Oil Contamination

The inlet non-return valve protects the vacuum pump against counter-rotation in the event of stopping without venting. This device also protects the point-of-use against back-sucking of oil. The oil separation circuit of the GVS A has also been optimized to minimize oil vapours in the exhaust gas. Thanks to their compact, space-saving design, all the models can be installed quickly.

The larger models in the series, GVS 470 A and GVS 630 A, benefit from further design improvements. The ball bearings feature permanent lubrication and are isolated from the process. This prevents bearing contamination, extends service intervals and further improves reliability. A special lubrication system also ensures homogeneous temperatures of the rotors without local overheating. This ensures better conditions for the oil and protects the pump. The guided rotary vanes reduce noise level and also extend the service life of the pump. In addition, they allow higher intake flows at lower pressure, reducing cycle-times and improving productivity.
