EVR-7000

The EVR-series are robust Vacuum Roots Booster Pumps

These Roots pumps are excelent tools to boost up your pumping speed and the reach a much better ultimate vacuum. These EVR-series Roots pump are useally combined with the pre-vacuum pumps of the following series: EV-series, EVD-series, EVSW-series and EVSL-series. The pumps can be supplied with two options: the bypass system and valve, this bypass system allows the Roots pump to be started already at atmosphere at the same time as the pre-vacuum pump. Teh second option is the magnetic drive, this magnetic drive eliminates allows the pump to run without a shaft seal, so it reduces downtime and service costs. Due to the lower ultimate vacuum the pump is oftenly used in applications like:

  • Vacuum packaging
  • Vacuum metallurgy
  • Thin film coating
  • Spae simulation
  • Freeze drying
  • Vacuum impregnation
  • Low density wind tunnels
  • Vacuum distillation
  • Drying and de-gassing
