The CDX1000 dry vacuum pump from BOC Edwards is ideal for high speed, high capacity process applications, and features third generation double-ended screw technology for reliable operation and low cost of ownership. With a nominal pumping speed of 900 m³/h, the CDX1000 is suitable for use in chemical, pharmaceutical, metallurgy and other industrial applications. Third generation screw technology employed in the CDX range features a pair of variable pitch rotors machined to exacting tolerances with no need for coatings or a compression plate at the exhaust. The double-ended design removes the issue of axial forces on bearings giving increased bearing life. This is a problem with traditional screw designs, particularly when handling liquid slugs or viscous oils and tars. Variable pitch geometry provides staged compression along the length of the screw resulting in lower running temperatures and lower process power consumption. CDX1000 has no lubricants under vacuum.
