Chemical Vacuum Pump Applications

NASH chemical vacuum pumps are the industry's preferred choice because they safely and reliably handle explosive gases and corrosive vapors. Click on the links below to learn more about how Nash chemical vacuum pump and compressor technology can best serve your application needs.

Versatile Product Technology

Our range of products can be individually applied or combined into packaged systems with additional components to serve a variety of process demands. From hermetically sealed pumps that eliminate leakage to engineered hybrid vacuum systems that optimize efficiency, we deliver smarter solutions custom-tailored to your specific requirements.

Liquid Ring Technology

Nash knows the technology behind liquid ring vacuum pumps because we invented the liquid ring principle of operation. These pumps operate at low temperatures and are suitable for handling liquids, steam, and condensate. Developed for the toughest applications, liquid ring vacuum pumps can safely and reliably handle explosive gases and corrosive vapors. In demanding processes such as distillation, solvent recovery, and vapor recovery, they are often paired with vacuum boosters, condensers or ejectors to overcome pressure limitations and achieve deeper vacuum levels. Requiring minimal care and known for extremely low maintenance, NASH liquid ring vacuum pumps—especially when integrated with booster systems—provide years of dependable service thanks to their robust design, rigorous quality, and simple operation. With low operating costs and an extensive performance range, our vacuum solutions excel across a wide spectrum of chemical and industrial applications.
