Nash - Two Stage Liquid Ring Vacuum Pump (AT706)

The AT706 is a two stage liquid ring vacuum pump engineered for demanding condenser exhaust applications in industries such as chemical processing, petrochemical, and power generation. Featuring an integral two stage rotor, this pump achieves deep vacuum levels down to 0.8 inHgA (28 mbar abs), approximately 40% lower than single stage alternatives. Its patented variable conical porting design minimizes bearing loads and optimizes performance across a wide operating range. Key features include high liquid carryover tolerance, side discharge to reduce flooded start risk, and a self-priming design that may eliminate the need for a booster pump. Constructed with a cast iron frame for durability, the AT706 is suitable for handling saturated process gases and vapor recovery or disposal.
