Dry screw vacuum pumps are environmentally friendly as there is less oil to dispose of and maintain within their design. These pumps are more efficient than a liquid sealed model and are well suited for industrial and process applications. There is no oil or water in contact with process gases.

NES Company, Inc. offers the NSP series dry running twin screw vacuum pumps achieving up to 7.5x10^-3 Torr deep vacuum levels and 77 to 1766 CFM flow capacity making them suitable for various applications such as degassing, distillation, drying, evaporation, filtration, lyophilization, impregnation, membrane pervaporation, vacuum refrigeration, vacuum furnaces, and vapor recovery units in the Chemical, Petrochemical, Pharmaceutical, Plastics, Beverage, Food, Building Materials, Defense industries, and more. The variable pitch design enhances energy efficiency by compressing the gas throughout the pump body and allows for effective cooling and energy reduction compared to constant pitch screw designs. The NSP Series comes side or bottom-discharge configurations with various other accessories and variations available depending on the appropriate system for the given application.
