ROOTS PUMPS

For all low and medium vacuum applications The OktaLine series Roots pumps can be perfectly tailored to customer-specific requirements by different pumping speeds and versions. This type of pump needs a backing pump both suited to the application and designed for the gas stream. The high-precision production technology makes it possible to achieve very high compression values, which in turn allows for maximum pumping speed at very low gas exit temperatures. Pfeiffer Vacuum Roots pumps offer low operating costs at high uptime, since electrical power and (depending on the process) a gaseous...

Convection-cooled – OktaLine Gas-circulation-cooled – OktaLine G Explosion-protected – OktaLine ATEX (in accordance with Directive 94/9/EC) Magnetic coupling as an option of all models The integrated overflow valve is standard in all convectioncooled pumps. This makes it possible to switch the pump on at atmospheric pressure. The pump is thus automatically protected from thermal overload. The gain in additional pumping speed allow for shorter cycle times in load lock applications and time-critical processes. Monitoring with fault-prone pressure switches and slow start up with cost-intensive...

Convection-cooled OktaLine Roots pumps for all low and medium vacuum applications Customer benefits The pumping speeds of convection-cooled Roots pumps range from 145 to 27,400 m3/ h . They can easily be combined and used in low and medium vacuum applications . Typical uses include industrial applications, coating, the semiconductor industry and research and development, or in chemical and process technology applications . The gear box and bearings in our Roots pumps are separated from the gas pumping chamber. The contactless operating principle of the Roots pistons allows for technically...

High differential pressures with lower power consumption High pressure ranges and maximum differential pressures, in continuous operation up to 870 hPa, are ideal operating conditions for gas-circulation-cooled Roots pumps in the OktaLine G series. At various power ratings from 5.5 kW up to a nominal rating of 200 kW, a pumping speed of 210 to 12,000 m3/h can be achieved. Gas-circulation-cooled Roots pumps can be operated without backing pumps. Thanks to the frequency converter, energy use can be significantly reduced. Pumping speeds can be precisely adjusted. Gascirculation-cooled Roots...
