Liquid Ring Vacuum Pump Large Capacity, 2BE4The 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 1,150 to 18,900 ACFM (1,950 to 32,100 m³/h), the 2BE4 is well matched to demanding environments like the paper, power, mining, and chemical process industries.
Reliable and Efficient with Proven PerformanceThe 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 CapabilityThe 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.
Robust and low maintenance based on proven flat sided 2BE designPatented in Germany in the early 1900’s, Nash’s flat sided liquid ring vacuum pump / compressor design has been providing thousands of facilities across the globe with proven performance, reliability, and peace of mind. With constant innovation, our patented design features:
- Port plates with variable porting so pump performance is optimized across the entire operating range.
- Large differential pressure capability
- High liquid carryover tolerance
- Large inspection ports allow for easy internal inspections
- Orifice to drain pump completely when shut down
