We offer high quality High Vacuum Refrigerator Pumps which are oil sealed and are made as per rotary vane design. These pumps are provided with an eccentrically mounted rotor, which is fitted with two radically sliding vanes that sweeps the stator volume twice per revolution. A volume of gas is compressed and ejected through the exhaust, as the vanes pass the intake port. In this ways, the pressure at the fore stage is reduced and vacuum is created.
- Ultimate vacuum is produced as high tolerances and oil film lubrication maintain exceptionally high clearances
- Our double stage pumps have a cascade system
- Gas ejected from the first stage passes to the intake port of second stage, thus achieving higher ultimate vacuum
- Superior flow rates are achieved at lower pressure
