Nash industrial vacuum technologies support critical processing operations around the world. From established industrial sites to new decarbonization and process optimization projects, Nash helps customers create and maintain the vacuum conditions needed for reliable, efficient production.
Vacuum plays a vital role in applications such as drying, filtration, evaporation, distillation, degassing, deaeration, vapor recovery, condenser exhausting, and gas removal.
The right vacuum approach depends on process conditions, operating goals, utilities, gas composition, environmental requirements, and lifecycle expectations.
NASH liquid ring vacuum pumps are a reliable and durable solution for challenging process applications. Our liquid ring vacuum pump design was the first-of-its-kind at the turn of the 20th century and has been an industry leader ever since.
Hybrid Ejector with liquid ring vacuum pumps
Selecting the right vacuum technology starts with the process. Gas composition, vapor load, moisture, contaminants, target pressure, operating temperature, utility availability, and maintenance expectations all influence the best solution.
Nash helps customers evaluate these variables and determine whether a liquid ring, dry, ejector, hybrid, oil-sealed, or engineered vacuum system is the right fit for the application.
