Italian pharmaceutical company Phamacia has installed six BOC Edwards dry vacuum pumps equipped with flame arrestors, explosion-proof instruments and local control cabinets
With a nominal pumping speed of 900m3/h, the CDX1000 is designed for use in pharmaceutical and industrial applications.
It is ideal for processes that require high pumping speeds, and in many applications can be used in place of two or more dry pumps for a highly cost-effective solution.
BOC Edwards innovative third-generation screw technology employed in the new 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.
Designed as a "dry" system, the CDX1000 has no lubricants under vacuum.
This means there is no possibility of process contamination and a reduced environmental impact, as regular replacement of contaminated oil is not required.
The bearing and gearbox lubrication system is cooled and filtered with easily accessible "spin-on" filters, further reducing the cost of ownership.
