Dry vacuum pumps do not use water or any other liquid for sealing or lubrication. Therefore, eliminating the risk of process contamination, effluent generation and corrosion due to always pumping in the vapor phase. These vacuum systems represent the best cost of ownership in their operating range due to lower installation expenses, easier maintenance, and the lowest running cost as well as reduced environmental impact. Furthermore, modular dry vacuum systems provide a clean, flexible vacuum and easily adapt to changed processes and operating pressures.
NASH modular dry vacuum systems for chemical and pharmaceutical applications uphold strict environmental standards by recovering and recycling valuable solvents without any need for further purification. Moreover, dry vacuum systems are energy-efficient because they require less burning of fossil fuels and reduces greenhouse gas that contributes to global warming.
