NES is proud to offer the NCC Series, a complete line of close-coupled liquid ring vacuum pumps to serve the industrial market. These pumps provide twice the efficiency per horsepower when compared to water jet pumps, and can easily digest debris, condensables, and other contaminents that are not appropriate for rotory vane pumps. Liquid ring technology utilizes a liquid seal to perform compression and produce a vacuum. Because liquid is used to perform mechanical compression these pumps have no internal contacting parts reducing internal mechanical wear. These pumps are available in cast iron/bronze fitted and stainless steel.
