Piston Vacuum Pumps

These are improved versions of the old Stokes Model 412 and 612 for industrial roughing vacuum applications. Capacities of 300 CFM and 500 cfm. Our oil-sealed rotary piston vacuum pump are self-contained, unit that can be paired with vacuum boosters for added capacity or vacuum level. The piston is driven by an eccentric mounted on the drive shaft and the piston slide is guided by two floating hinge bars that are free to oscillate in the pump housing.
