The 2BE4 vacuum pump produced by ZHAOHAN PUMP was developed from the proven NASH 2BE3 pumps, whose reliable performance has been further improved.. We offer same outline dimensions for bolt-on replacement and equivalent performances.
The footprint and connections to the 2BE4 models are identical to its predecessors, the 2BE3 pump. Therefore, exchanging or upgrading to the more efficient 2BE3 requires no site modifications.
The 2BE4 model is available in cast iron, with stainless steel . The 2BE4 is perfect for use in mining, filter applications, paper mills, power plants, chemical plants, refineries and more
Our 2BE4 pump can serve application from 1500m3/h to 38100m3/h.
