Hanbell PD2602, the pump forvacuum oil-free screw with a busterny step of Ruts and the inverter

 Modern hi-tech appendices impose increased requirements to purity and speed of receiving vacuum in the pumped-out volume. Now the tendency of disposal of use of oil vacuum pumps was outlined. Well-tried and modern remedies for ensuring oil-free forvacuum pumping are screw vacuum pumps. The contactless principle of action together with lack of greasings and working liquids in a vacuum chamber of the pump allow to provide high purity of the gas environment and excellent reliability even during the work with the aggressive, active or containing firm particles gases. The company RUBBED delivers the universal oil-free screw vacuum pumps Hanbell ^{(Taiwan) with a productivity of 80 - 800 m3/h} (limit vacuum to ^10-3 Torr) and otkachny posts on the basis of screw pumps and busterny two-rotor ^{pumps with a productivity of 600 - 3600 m3/h} of Ruts (limit vacuum to ^10-4 Torr). Despite high efficiency of the offered pumps their design allows to lower costs of the consumed electric power significantly. Scopes of oil-free screw vacuum pumps:

• Oil-free pumping of systems of modeling of a space
• Chemical and pharmaceutical industry
• Semiconductor and optical production
• Vacuum decontamination and drying
• Vacuum metallurgy

The best replacement to outdated pumps and units of the NVZ and APZ series!

Characteristics

In video given below it is shown how the vacuum screw pump Hanbell copes with pumping, despite a large number of firm particles. At the same time, this procedure did not become the reason of a stop of the screw pump or its exit out of operation.
