NP Series Single Stage Dual Cone Liquid Ring Vacuum Pumps
A higher ratio value indicates that a given pump yields more CFM per unit HP.
Our 80-1160 HP NP Series vacuum pumps are designed to be drop-in replacements for Nash Classic Premier Series liquid ring vacuum pumps. These pumps boast split vacuum capability, made possible only by the center shroud design that creates vacuum operation with significant vacuum pressure differentials. The Premier Series allows for efficient operation across its entire capacity and vacuum scale. This, in addition to its rugged exterior, yields the perfect design for operation in harsh environments that require high capacity such as paper, power generation, mining, chemical, and petrochemical processes. NES offers models 2160, 2200, 2280, 2370, 2480, and 2620. Vacuum levels range from 4-24.5” Hg.
