2BE3 & 2BE4 Liquid Ring Vacuum Pumps & Compressors

2BE4 Liquid Ring Vacuum Pump and Compressor

1500 - 19000 CFM / 2,500 to 33,000 m³/hr

The NASH 2BE3 & 2BE4 vacuum pump & compressor series offers capacities ranging from 1,500 to 19,000 CFM (2,500 to 33,000 m³/hr).

Designed to operate in demanding environments like the paper, power, mining and chemical process industries, these pumps offer durability and reliability at a low cost of operation. Each model is equipped with an application-proven polyisoprene-lined body for added corrosion & erosion resistance.

The unique inlet configuration allows for both top and side inlet arrangements to accommodate low headroom installations. In installations where space is limited, the top discharge capability of the 2BE4 allows the use of a top mounted discharge separator that saves floor space and eliminates the need for a trench.

The 2BE3 & 2BE4 models allow efficient operation over the entire vacuum range without the need to change the pump's internals. When equipped with a center shroud, split vacuum operation up to 12 in. Hg (400 millibar) differential can be achieved. Large inspection ports allow easy access to pump internals for inspection and maintenance.

For more aggressive applications, stainless steel, stainless steel clad and epoxy coated components are available.
