Better vacuum pump system performance

Edited by the Processingtalk editorial team Dec 7, 2007

Delivering higher levels of performance but with lower operating costs is always a tough 'double' to pull off, but Busch (UK) claims that its new Combi Series vacuum pump does just that

Conventionally, the only way to increase vacuum performance is to install more primary vacuum pumps - a solution that works but also means higher operating costs.

Busch (UK) says its new Combi puts an end to that.

The Combi Series overcomes that problem by providing a multitude of possible combinations that use a mix of roots-type pump and 'backing' vacuum pump to reduce evacuation times and improve ultimate pressures and pump capacity.

The result is improved performance and a solution that is more cost effective than a conventional increase in the number of primary vacuum pumps.

Allied to the wide range of Busch vacuum pumps, the Combi Series provides the end user with an array of adaptable options to handle a variety of working pressures and capacities.

Each vacuum unit can be individually configured to the process conditions and the gas/media to be handled.

2 Busch Combi vacuum units can be used in a wide range of industries and in all vacuum ranges from atmospheric pressure down to less than 3 x 10-3 hPa.

Standard pump configuration capacities up to 4,000 m3/hr can also be achieved, while greater capacities and ultimate pressures can be catered for through bespoke designs.

The Combi units come in two configurations: the booster pump directly flanged to the inlet of the 'backing' pump or both booster and 'backing' vacuum pump mounted on a common base frame.

Both designs are said to offer an extremely compact footprint compared to large capacity stand-alone pumps.

The choice of 'backing' vacuum pump can be either the popular and successful R5 Series oil-lubricated rotary vane pump or the acclaimed COBRA rotary-screw vacuum pump which provides a totally dry-running solution.

Busch says that its new Combi units can be used in a wide range of applications and industries including metallising and PET coatings, glass and foil coatings, optical coatings, heat treatment furnaces and chemical and pharmaceutical applications.
