N904 / N905 Series Pulp & Paper Vacuum Pumps & Compressors
Typically Ships From Stock
Our 30-900 HP pulp and paper vacuum pumps are designed as drop-in replacements for Nash 904 vacuum pumps. This high efficiency 20-vane rotor design rotates at relatively slow speeds for higher reliability, less wear, and lower power consumption with functionality as both a vacuum pump as well as a compressor operated at wide ranges of rotations per minute. The N904 is ideal for pulp & paper, geothermal power generation, and other high reliability high capacity applications. We offer the L through U models with capacities ranging from 2,200 to 17,200 CFM. Vacuum levels range from 5-27.5” Hg when used as a vacuum pump and reach up to 14.7 psia when used as a compressor.
