Rotary Piston Vacuum Pumps are quiet running and designed for minimal vibration. These rugged, oil-sealed vacuum pumps are capable of ultimate pressures as low as 0.2 microns.
Flow range: 5 - 780 CFM (8 - 1320 m³/h).
Ultimate pressures: to 10 microns (1.33 Pa) single stage to 0.2 microns (0.13 Pa) two-stage
Liquid Ring Vacuum Pumps are ideally suited for pumping wet mixtures and even slugs of liquid. They are available in standard, all iron construction and stainless steel.
Flow range: 10 - 990 CFM (17 - 1680 m³/h).
Ultimate pressures (also dependent on vapor pressure of sealing liquid): to 25 Torr (1.33 Pa) single stage to 4 Torr (0.13 Pa) two-stage
Rotary Vane Vacuum Pumps provide an economical vacuum source for those applications where the process is relatively clean or filtered. Gas ballast valves for vapor handling applications are included as standard equipment.
Dry Screw Vacuum Pumps operate without any sealing liquid in the pumping chamber. Without metal-to-metal contact inside the pumping chamber, wear is greatly reduced.
Flows: 71 - 750 CFM (120 - 440 m³/h).
Full pumping speed to 1 Torr (1.3 mbar abs); ultimate pressures to 0.02 Torr (2.7 Pa)s.
