Variable Pitch Two Screw Vacuum Pump

Our Dry-Running Variable Pitch Two-Screw Vacuum Pump.  We are proud to present our NSP Series variable pitch dry twin screw vacuum pumps.   Dry Screw Vacuum Pumps are known to be the most efficient vacuum pumps, bringing some of the best CFM/HP ratios in the industry. The defining physical principles that makes the pump advantageous are the isolation of the process material and deep vacuum capabilities.

The pump uses a pair of helical screw rotors with variable pitch to displace and compress process material, resulting in up to Torr of ultimate vacuum for a vast array of research, analytical, and chemical applications that require 77 to 1766 CFM and high vacuum levels.  The unit comes in side- or bottom-discharge configurations with various other accessories and variations available depending on the appropriate system for the given application.

This is perfect for 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 Dry Screw Vacuum Pump offers the following:   Robust Construction: Standard construction is cast iron with PFA internal coating for resistance against adherent process substances, providing for a secure pump outside and inside.  

Versatility: We are able to reach up to 7.5×10^(-3) Torr and 77 to 1766 CFM for deep vacuum applications across industries with very different pumping needs and reliability in the harshest pumping loads.  

Low Maintenance: It simply requires regular oil changes on lengthy intervals. In the case of inspection or maintenance within the pump, the chamber is easily accessible.

Clean Process: The dry screw vacuum pump operates so that no grease or other lubrication is allowed to come into contact with the process material, allowing for a clean process with clean in, clean out through the isolated chamber.  

Wide Selection: We offer various configuration, variations, and accessories to include with the dry screw vacuum pumps.  

One-Year Warranty: We provide a one-year warranty against manufacturing defects for peace of mind during selection, installation, operation, and beyond.
