Our direct coupled double stage high High Vacuum Pumps (FTDC 50) are sealed rotary vane design. An eccentrically mounted rotor fitted with two radically sliding vanes sweeps the stator volume twice per revolution. As the vanes pass the intake port, a volume of gas is compressed and ejected through the exhaust, thus reducing the pressure at the fore stage and creating vacuum. High tolerances and oil film lubrication maintain exceptionally high clearances and produce high ultimate vacuum.
Our double stage High Vacuum Pumps (FTDC 50)have a cascade system. Gas ejected from the first stage passes to the intake port of second stage. As a result, they achieve higher ultimate vacuum and superior flow rates at lower pressure. Our High Vacuum Pumps (FTDC 50) are approved by Kirlokar Copeland & other OEMs.
