Liquid Ring Vacuum Pump Medium Capacity, 2BE1

Capacity 60 to 13,000 ACFM (100 to 22,500 m³/h)

Vacuum to 1 inHgA (to 33 mbar abs.)

The NASH 2BE1 liquid ring vacuum pump and compressor series covers a broad range of suction volume from 60 to 13,000 ACFM (100 to 22,500 m³/h), vacuum range to 1 inHgA (33 mbar abs.) and pressure of 50 psia (3.5 bar abs.). Based on the proven reliable flat sided liquid ring vacuum pump design the 2BE1 is available in 23 models, has a large differential pressure capability, and is ATEX Certified. For these reasons, the 2BE1 is one of the most popular liquid ring pumps worldwide and can be found in almost all industrial vacuum applications including the chemical, pulp & paper, and power generation industries.

Key Characteristics:
  • 2in1: Pump & Compressor
  • Versatile Performance and Broad Range
  • Robust and Low Maintenance Design
  • NASH Classic Pump Model


Backed by decades of reliable performance the 2BE1 liquid ring vacuum pump and compressor series continues to offer a cost-effective, reliable vacuum solution for almost all industrial vacuum applications. Available in 23 models, the 2BE1 product line covers a wide range of capacity sizes and is available in cast iron, stainless steel, and a combination of both materials.  

Robust and low maintenance based on proven flat sided 2BE design
Patented 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, NASH's 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

Operates as a vacuum pump and compressor with a discharge pressure range of 50 psia (3.5 bar abs)
Some applications require vacuum and compression in one process. Instead of handling the gas with two separate machines, our liquid ring vacuum pump and compressor models can do the job with only one pump - reducing cost and simplifying installation.

NASH Classic Pump Model
With more than 110 years of experience engineering liquid ring vacuum pumps and compressors, we know how to design products that last. As a result, our Classic liquid ring vacuum pumps and compressors, like the 2BE1, are still manufactured and are running in plants around the world today. Only true Classics manufactured by Nash are 100% performance tested and carry our factory warranty.
