2BE4 Liquid Ring Vacuum Pumps and Compressors An upgrade of Nash's 2BE3 vacuum pump series, the 2BE4 series offers capacities ranging from 1,500 to 19,000 CFM (2,500 to 33,000 m³/hr). This is achieved by modifications to the shaft bearings and through optimization of the port plates and the impeller. Improvements to internal flow channeling reduce the energy requirements by 6 to 8%. Optimization of the shaft bearings increases pump flexibility in the event of operational malfunctions and, ensures better lubrication, which extends the service life. An optional connection for rinsing the housing is also available. This feature improves cleaning and the service life.
