NASH 2BE1 Announcement

As with every Nash innovation, the upgraded 2BE1-7 started as a solution to a real-world customer challenge. When a chemical customer required more efficient performance for chemical processing with higher discharge pressures, Nash R&D went to work. We expanded the existing 2BE1-7, developing a product that not only met the customer's spec and price requirements - it delivered efficiency gains over comparable liquid ring compressors.

The 2BE1-7 is available in stainless steel and cast iron, with optional mechanical seals and an inlet/outlet manifold. With a differential pressure capability of up to 35 psig (3.5 bar abs), the 2BE1-7 covers a wide range of operating conditions and process applications, including: VCM recovery, explosive gas compression, filtration, solvent recovery and vapor recovery.

Time-tested and proven reliability, now with the capacity to tackle your toughest chemical and petrochemical operations. Smarter Works Harder.
