2AL Series Two/Double Stage Liquid Ring Vacuum Pumps are designed and manufactured for use in the most critical applications. Their main feature is that they can suck contaminated gas mixtures, aggressive gases and vapors, and explosive gases and vapors of any nature down to a conventional end vacuum of 33mbar(abs).

Produced according to highest quality standards, Two/Double Stage Liquid Ring Vacuum Pumps belongings to 2AL-series which are “In-Between Bearings’ version and it is more robust during operation when cavitation and vibration occurs.

2AL Series Two/Double Stage Liquid Ring Vacuum Pumps are available in different material to withstand variable process condition.

Advantages of Two/Double Stage Liquid Ring Vacuum Pumps

 2AL Series Two/Double Stage Liquid Ring Vacuum Pumps are two-stage type for deep vacuum enabled by optimising the compression ratio between two impellers operating in series. Designed to provide maximum efficiency at deep vacuum, the 2AL series liquid ring vacuum pumps have in addition the below advantages:

• Complete line from 3 to 55 kW (11 models)
• Wide range of applications
• High reliability and low maintenance 
• Possibility to handle almost any gas and vapour with associated liquid carry over
