The NASH 2BE4 liquid ring vacuum pump and compressor series have been optimized to deliver a 6-8% efficiency improvement over previous 2BE models. Based on the proven reliable flat sided liquid ring vacuum pump design the 2BE4 has a polyisoprene lined body, flexible inlet and discharge connections, and a large inspection port for improved performance and reliability. With capacity ranging from 1,200 to 19,000 ACFM (2,000 to 32,300 m³/h) the 2BE4 is well matched to demanding environments like the paper, power, mining, and chemical process industries.
Reliable and Efficient with Proven Performance
The 2BE4 liquid ring vacuum pump and compressor series is an upgrade to the proven 2BE3 model and has been engineered to deliver improved performance, reliability, and efficiency over the previous models. Compared to previous models the 2BE4 offers efficiency improvements up to 8% and has reduced maintenance requirements.
Split Vacuum Capability
The 2BE4 pumps 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 inHg (400 millibar) differential can be achieved. The advantage of this is significant because it allows the use of fewer vacuum pumps–which saves space and installation costs.
